Chapter 4 Enlightenment in the Iron Field

The impetuous traverser finally put his feet on the ground and set his sights on the animal power machine.

The animal power engine was not eliminated in the steam age, and there was a boom in the fifties and sixties in my hometown.

For example, an animal-powered root-washing and seedling transplanter, a combined animal-powered harvester with 30 horses, and an animal-powered water well with 10 catties of grass per ton of water.

There are also animal-powered trenchers, animal-powered supporting grain precision seeders, animal-powered reciprocating saws and so on.

As an engineering dog at Tongliao University of Technology, it is also very reasonable to have seen the drawings.

Vondolph plans to design an animal-powered air hammer.

Similar to a large treadmill, it has a sloping crawler design with a shaft under the wooden tracks, and a large flywheel is mounted on the shaft to adjust the rotational speed.

A cow or horse runs on it, changing into a slewing force, and then this force is driven by a pulley to the wheel, lifting a hammer and forging a workpiece.

Although the operation efficiency is very limited, the lack of firepower can increase the scale!

There are more than a dozen cows in the family, and they are made bigger, and if one is not enough, there are two.

Two cows work at the same time, which can already ensure a stable output power of more than 1 horsepower.

It's not enough to have three heads, how can it be enough to forge a farm tool or something, but it really can't be done, and there are two horses at home.

Name: Happy Cow and Horse Machine!

Vondolph had already planned the family's livestock.

But he never thought that the livestock in the family would not want to be the lord's cattle and horses!

Although the ox has a gentle personality and great strength, its work efficiency is low, and it is not in a hurry to do any work.

And the cow is just gentle, not really temperless, you are in a hurry and want to whip it, Brother Niu is not used to you, and sits directly on the ground.

Big Brother Niu strikes!

Horses work efficiently and have a strong memory, but they will strike after a long time of hard work.

And the horse is easily frightened, and it is necessary to reassure it all the time, otherwise it will feel insecure.

Then strike.

If you don't serve them well or let them be in a bad mood for a long time, they will lose weight and grind foreign workers, or they will get sick and lose their ability to work.

They are still very emotional, and if you don't take them out for a walk for a long time, they will be depressed.

Moreover, depression will also spread among the group, once you have depression, your appetite will drop significantly, and you will lose weight and grind foreign workers.

Then strike.

Master Feng Daofu looked carefully for half the night, and only then did he see the words in the cracks, and there were two words written all over the book: strike!

It's okay for engineering dogs to design machinery, but how to make animals obedient...... There are no old professors at Tongliao University of Technology in Jienyima!

"There is the adaptability of a donkey, but there is no stubbornness of a donkey; There are horses with efficiency and strong memory, but not as bad as horses' stamina; It has the docility and persistence of a cow, but it is not as pretentious as a cow...... Why doesn't there be such a perfect animal in nature? ”

Master Vondolph was very sad.

The animal power machine plan was put on hold.

Wait until there are enough people to train the animals before proceeding.

The old man was ruthless: "Today I must use the machine to strike iron!" ”

"Why can't I exploit you cattle and horses, and I can't exploit myself?"

Vondolph picked a log, and the knife cut it into a wheel shape little by little.

"Use a knife, +1 with one hand"

"Use a knife, +1 with one hand"

......

"One-handed upgrade!"

"Gain the Specialty - Dialing Skill (+20 for One-Hand Control)"

[One-Handed Lv1: Specialty - Diagling Skill (+20 One-Handed Control)"

The knife suddenly became a big bit more flexible.

Feng Daofu waved a few times, like an arm command, but the accuracy was indeed higher.

"Not bad."

With his new expertise and the fact that he has become more skilled in carpentry, Vondolph has greatly improved his efficiency.

In a few moments, a few wooden wheels with grooves around the perimeter were cut and a pedal was made.

Skill upgrades, coupled with control +20, the machining accuracy is already a skilled worker, which is enough to meet Feng Dolph's vision.

Feng Dolph took out wrought iron and a small hammer, added fixings to the wheel, and stood on the ladder and fixed it on the top of the stake anvil.

After looking back and forth several times to make sure that the position was not wrong, Feng Daofu first chiseled the hole, and then used the wooden wedge as an expansion screw, and slammed a few hammers to fix the small wheel.

"You built a pulley set, Project +4"

"Project Lv0 (67%)"

With a little bit of effort, it's very firm.

A little more effort...... Forget it, it's not to lift heavy objects, or to hang a large forging hammer of more than ten kilograms, and the strength test is not necessary.

Vondolph got the pulley set in order, the sledgehammer was hoisted, and the pedals were placed at his feet.

Looking up and down, there is a slight deviation in the landing point.

Feng Daofu half-squatted down, adjusted the wooden stake and anvil with a pull, and took a piece of iron to practice.

"First test run."

Feng Daofu holds the small hammer in his right hand, and clamps the iron with his left hand to adjust the position.

Lean forward when the hammer is lowered, exert force on the sole of the left foot, and press the pedal to the end.

Zizi!

With a slight grinding sound, the pulley group pulled up the sledgehammer.

Feng Dolph observed it for a while, and was not very satisfied: "The shaking is a bit strong." ”

"There is a problem with the balance of the pulleys."

The machining accuracy of the skilled worker level is enough, but after all, there is no experience, and the details still need to be adjusted.

"You improved the pulley set, engineering +1"

The balance is solved.

Feng Dolph lifted the hammer, leaned back, and released the pedal with the sole of his left foot.

Zizi!

The sledgehammer fell with gravity, making a heavy sound of gold and iron!

Clang!

"Forge Practice, Forge +8"

"Forging Lv. 1 (45%)"

Vondolph's concentration was so focused that he didn't notice the news.

He felt that the angle didn't seem to be very right, and adjusted it again.

"You improved the pulley set, engineering +1"

There was no major problem this time.

"Just call the boss happy machine!"

"I'm happy!"

A small hammer, a big sledgehammer.

The movements are silky smooth, and the process is very much like a pedal sewing machine.

Vondolph also calculated the kinetic energy by the way, and knocked about 200 joules at a time.

Because it is not vertical, there is a certain angle, and the vertical axis becomes shorter, and the actual momentum of the iron material will decrease, which is equivalent to a decrease in the efficiency of forging.

Feng Daofu suddenly noticed something: "If I use the long rod forging hammer myself, according to the increase of the lever of the long rod, plus my own strength, the strength of the forging by myself is far greater than this simple manpower air hammer...... My invention is useless? ”

Feng Dolph was stunned for a second.

Then I decided I didn't want to think about this complex issue anymore.

He paused the work of the improvised manpower air hammer and carefully inspected the furnace to see if there were any leaks, leaks, or residues in the lining.

The stove is in good condition, relatively new overall.

"The blacksmith seems to have said that he only did maintenance after the peak season passed last month......."

Feng Dolph took a look, a little dissatisfied.

He really wanted to replace it with refractory bricks immediately, and then go to the small blast furnace of the soil method, and then iterate himself to start industrial ironmaking.

But the failure of the generator and the animal power machine taught Vondolph too much of a lesson.

"There's no kaolin right now, and I'll wait until next year to do free trade on the island of England."

"Let's keep our feet on the ground now."

After checking the stove, Vondolph prepares to burn charcoal.

In modern times, some people can't light charcoal for barbecue, which shows that charcoal burning is a technical job.

Forging Lv1 gives the specialty - High Efficiency Charcoal Burner, the panel text description is Charcoal Burning Efficiency +50%.

As a scholarly engineering dog, he felt that this expertise could be used in wood distillation, and when the stables were ready, he would build a dry distillation kiln.

At the same time, the text is transformed into reality, and there is also a one-handed operation +20 given by the one-handed specialty, and Feng Dolph can feel that his fingers have become very flexible, or is it that the ability to recruit nerves in the muscles of the forearm is stronger?

In short, +20 for one-handed control of the Dialing Skill is not only only suitable for one-handed weapons and tools, but can also be of great use in life.

"There's more value to be developed in expertise."

Thinking of this, Feng Dolph picked up his two-handed axe and placed the coarse log on the wood-splitting artifact he had invented.

The overall image resembles a round trash can.

In the middle is a pointed beam, and the wood is fixed to the pointed head by tapping it first, and the log will be firmly fixed and will not move.

The large wooden pier at home also has a similar fixed design, and a hole is buckled in the center of the circle, and the wood can be inserted into it to split, which is very efficient.

But the height is not suitable for Feng Daofu, and the chopping force is a bit wasteful, so he invented a wood-chopping artifact whose height is more suitable for his height.

——The stake anvil also has the problem of not fitting the height, picking up the sledgehammer and scrapping the waist, for the sake of a happy life in the future, Feng Daofu is obsessed with developing mechanical power.

While his body was still warm, Vondolph stretched briefly, maintaining a boxing stance, keeping a good distance, holding the bottom with one short grip and the other.

Kick the ground, the calves and thighs tense, and the bent knees become straight knees.

The gluteus maximus muscle is tense, the hips are twisted and the waist is twisted, the whole body is coordinated, the waist and abdomen are tensed in the rotation, and the shoulders are sent out, and the explosive power and enthusiasm of the human body's rotating chain are all smashed to the log!

"My invention is useful!"

Bang!

Click!

The coarse log is split in half!

"Kinetic chain training is underway, +2 for both hands"

"Both hands Lv0 (63%)"

Chopping firewood is a technical job, and it is difficult for beginners to chop even the finest firewood.

Master the power skills, 1 and a half pounds of one-handed axe can easily split fine wood.

If you are proficient, you can chop coarse wood, use a 10-pound axe, follow a line of wood, first smash a small gap, and then continue to smash into this gap, and you can smash it open to a certain extent.

If you are a little more fierce, you can use a two-handed axe of more than 20 catties, and an axe is a coarse firewood.

Feng Dolph's strength is as high as 11 points, and he uses a two-handed axe!

Click!

Feng Dolph replaced the new coarse logs, raised the axe again, and his whole body was synchronously exerted, which was both a chopping wood and a training power chain.

"Kinetic chain training is underway, +2 for both hands"

"Kinetic chain training is underway, +2 for both hands"

......

Feng Daofu didn't even gasp for a few dozen splits.

Throwing aside a garbage log with a wooden knot and chaff, Feng Daofu adjusted while chopping, and also felt the force of his own muscles.

The measure of real-world strength is mostly quantified by the weight of pushing, pulling, and squatting.

Take the deadlift, a symbol of human strength, for example, which is the best test of Vondolph's current conditions - the deadlift only requires lifting the weight from the height of the calf to the height of the waist.

For a standard body type, the deadlift weight of an ordinary social animal that does not exercise regularly is 50kg.

The panel is 11 points of strength, if you press the data, it is 110kg, theoretically not as good as the iron slave.

The status of the iron slave is low, but the strength is stronger than that of an adult Norse warrior, and when he acts as a porter, he can carry two or three hundred pounds of heavy loads.

And his strength performance is much stronger than that of fighting iron slaves.

It stands to reason that strength comes from such a composite unit of nerve + muscle, also known as the resistance ability of neuromuscular synergy.

But the power on the panel, Vondolph feels that it is strength = muscle.

The weight remains the same, the strength is faster, the muscles are more resilient, the heart's pumping ability and the lungs' ability to absorb oxygen are stronger, resulting in improved endurance...... Changes across the board.

It is not so much strength, but the basic athletic ability of the human body, which includes strength, speed, endurance, coordination, flexibility, agility and other sports qualities.

As for whether it is a speed type or a strong man type, it is estimated that it depends on weight and body type.

"110kg may be normal power, but ...... extreme power"

Feng Dolph turned up the Eppley formula popularized by his roommate who is fond of powerlifting: "My deadlift limit is 180kg. ”

"Outrageous."

Strength is calculated based on one's own weight.

Vondolph weighs only 60 kilograms, and his deadlift limit is three times his own weight.

Many excellent professional powerlifters have extreme deadlifts that are three times their body weight.

Vondolph is now under age punishment, so that he can reach the professional level.

"Weight is the cornerstone, and strength is the amplifier."

"The average adult strength 5 can lift a weight equal to their own weight."

"Through training, you can become an amateur veteran who can pull twice your body weight, and your strength attribute will also improve...... Pretty reasonable. ”

Click!

"Hands up!"

"Gain Specialty - Powerful Grip (+20 with Two Hands)"

"Two Hands Lv 1: Specialty - Powerful Mastery (Two Hands +20)"

Feng Dolph felt that the control accuracy of the two-handed axe was much higher.

He replaced the new logs and drew a line in the middle along the grain of the wood.

Vondolph raised his two-handed axe.

Click!

"Kinetic chain training is underway, +2 for both hands"

The axe slashes the center line with precision!

Feng Daofu exhaled turbidity: "Don't worry about not being able to control the two-handed forging hammer now." ”

Grunt~

I've been busy for so long, and I'm a little hungry.

Vondolph went back to the house and ate a little bit.

As the food entered his stomach, Feng Dolph felt the soreness in his muscles gradually subside.

It's not normal to be fast.

Vondolph clapped his hands, knowing that it was the gluttonous trait at work.

The gluttonous trait makes him naturally have a very high metabolic rate, the same height and weight, eat more, get hungry faster, and become a dog without eating.

In ancient times, when productivity was backward, this meant that survivability was reduced, and famine was the first to be eliminated, so gluttony was a negative trait.

But on the other hand, if you can eat a full stomach, the body's metabolic rate is extremely high, but it can become a positive BUFF.

Because this means that the muscles are more energetic, the training can withstand several times the intensity of ordinary people, and at the same time, the recovery from fatigue is faster, and the wound heals faster, which is equivalent to a great improvement in the training effect.

Equivalent to a bonus of '+50% for Muscle Endurance, +100% for Training Feedback, +200% for Recovery Speed'.

And reflected in the panel, there is also a bonus of strength +1 and vitality +10 when staying full for a week.

Vondolf's satiety has long been resident.

As long as he is fed, relying on his extremely high metabolism talent, even if he has the same strength level, he can use three alone!

When you are tired, you will rest for a while, blink and squint, and then wipe your eyes and face with a wet towel dipped in cold water, as if you have shaken off all the fatigue of the previous half of the day, like a clockwork that has tightened its clockwork one turn at a time.

Vondolph continued to work energetically, getting the tools, materials, and quenching buckets ready.

Considering the difficulty and the need for farm tools, he was ready to quench with oil.

The oil quenching temperature drops slowly, and it will be much milder.

Water can only be boiled to about 100 degrees, so it is equivalent to a very cold thing for a high temperature of seven or eight hundred degrees.

If the thermal expansion and contraction are too intense, it is easy to have an accident if it exceeds the upper limit of tolerance.

Just like when Niu Niu was hot and rising, Niu Niu Ma suddenly pushed the door open, the stimulation was too strong, the cold contraction was violent, and it exploded on the spot beyond the upper limit.

Water quenching is a test of operation.

The operation is good, toughness and strength, and the ice will be broken if the operation is not good, and the transition point will not be grasped.

Although it is possible to reduce the boiling point of water and adjust the specific heat of water by adding salt, the required technology and experience are too high.

In some cases, it is just a farm tool, and Feng Daofu chooses oil quenching, which can also prevent metal oxidation, after all, there is also a small amount of oxygen in the water.

Putting on hard leather boots and a protective animal skin suit shaped like an apron, Vondolph began to heat the stove after doing his protective work.

Call!

Leather blowers blow oxygen in.

As the furnace temperature rose, Vondolph stepped on the blower with his feet and disassembled Surrey's long-handled sickle with his hands.

The long handle was set aside, the surface of the sickle part was cleaned, and Vondolph observed that the material was wrought iron.

"I thought it would be decarburized with cast iron, but wrought iron was to be expected."

After all, it's just a block of ironmaking process.

The difference between pig iron, wrought iron, and steel is the difference in carbon content.

Iron with a carbon content of more than 2% is called pig iron, iron with a carbon content of less than 0.05% is called wrought iron, and iron with a carbon content of 0.05%~2% is called steel.

To play with steel is to play with carbon.

A slight difference of one thousandth can make a huge difference in the metal properties of steel.

Feng Daofu thought of improving the long-handled sickle into a samarium knife, which could be six or seven times more efficient than a small sickle, and wrought iron could be forged, extended and quenched, but pig iron could not, and it was easy to strengthen and become fragmented.

"But there are also advantages to pig iron smelting technology."

Feng Daofu looked at the open low furnace, how to look at it and dislike it.

If the furnace is five or six meters or seven or eight meters high, one or two tons of pig iron can be produced in a day, the output advantage is obvious, the efficiency is relatively high, the residual iron in the slag is about 3% ~ 6%, compared with the iron content of the slag of the block ironmaking method is as high as 70% ~ 80%.

It is written in the history of metallurgy in the world that block ironmaking is suitable for direct and commonly used wrought iron, which saves fuel, has a low threshold and saves money, and is suitable for small-scale operations carried out by several people such as blacksmith shops.

The output of pig iron smelting technology is high, but it takes more than a dozen people to operate a furnace well, plus the manpower for smelting and processing, etc., the operation of a furnace requires dozens of people, and the consumption of manpower and material resources is relatively large, which is more suitable for large-scale industrialization and industrial production.

Feng Dolph didn't have so many people, so he had to make do with it first.

Anyway, it is all high-quality iron ore here, with high quality and few impurities.

The raw materials are good, and the tools are almost not a big problem.

The iron ore grade is more than 50%, and the original clay furnace can make iron in one piece.

But then again, if the iron ore is of high quality, it is actually more conducive to blast furnace technology, which can reduce the coke ratio of the blast furnace and increase the production, on average, the grade is increased by 1%, the coke ratio is reduced by 2%, and the output is increased by 3%.

Feng Dolph forcibly stopped the thought of tossing, waited for the furnace temperature to be about the same, and put the sickle in to heat up.

His eyes were staring at the color change on the surface of the sickle, and he was talking about the knowledge points: "material selection, cutting, forging, shaping, cutting, quenching, annealing, grinding, initial forging temperature, final forging temperature, ......

"The initial forging temperature of mild steel is ...... It's not steel! ”

Feng Dolph didn't know much about wrought iron, so he decided to use mild steel as a reference.

The initial forging temperature of low carbon steel is generally 1100°C~ 1200°C

The temperature of this medieval iron-making furnace cannot exceed 1300°C, but there is no need to worry too much about overheating.

"Barely made up the merits."

"When you have time in the future, you must redesign the air duct."

The core reason for the temperature of the furnace in the Middle Ages is that there is only 1 air inlet, only 1~2 air vents, and there is not enough oxygen.

The hometown has long been upgraded to four blast bags in the Qin Dynasty, which can not only make the oxygen in the furnace more uniform and burn more fully, but also increase the temperature.

The first step in updating the technology was to develop two channels for this low furnace, which could blow air in four threads, and then build a regenerator.

Now the furnace temperature is at most 1200 °C, barely enough, it is more than enough to play a sword, and a little diligent can also forge a hundred steels, at most the efficiency is lower.

For the first time since the crossing, it was really forged, and wrought iron was used, which was different from mild steel.

Feng Dolph plans to be on the safe side, lower the starting forging temperature, and start forging at 1100°C.

The final forging temperature of carbon steel is about 800°C, and at 850°C, it is put into the furnace for reheating.

At room temperature, the time consumed by natural cooling of 250°C will definitely be much less than that of 400°C, and the time left for Feng Dolph to forge is reduced by a single heating, and the production efficiency is reduced.

Limited experience, technology and conditions, can only suffer first.

It's better to be slow than to fail to strengthen, and it's cute to be short.

Feng Daofu judged the color of the fire, and watched as the color gradually changed from dark red to red, and the brightness gradually increased.

Different temperatures and colors of fire are different, and if you don't have instruments, you have to rely on your eyesight and experience.

"I now understand why blacksmiths like to strike iron in the dark."

Feng Daofu said: "The color is accurate at night, and it can also rely on the furnace temperature to heat at night." ”

His Spotlight Specialty, Nightcrawler, also improves his night vision by 30%, making it even more accurate.

When the color of the sickle reached a pale yellow color symbolizing 1100°C, Vondolph clamped the sickle to the stake anvil with iron tongs.

Hold the hammer in your right hand, hold the tongs in your left hand, step on the pedal with your left foot to control the sledgehammer, and keep your eyes on the iron to prevent it from stumbling.

Clang!

Clang!

Clang!

Flying up and down, there is only one right leg left in the busy limbs, and the scene looks like Tom's cat.

If it weren't for the fact that the control of one hand and one hand had been greatly increased, there would be no conditions for difficult operation.

It is not without benefit for Vendauf to toss himself like this.

Clang!

"10 minutes of hard forging, +10 forge"

Clang!

"10 minutes of hard forging, +10 forge"

......

Feng Dolph himself has a very high talent for engineering, and the panel gives a 300% forging learning rate bonus.

Superimposed, Feng Daofu's iron-striking talent is directly full.

It didn't take long for the experience gauge to be filled.

"Forge Upgrades!"

"Gain Expertise - Steelmaker (Steelmaking Efficiency +50%)"

[Forging Lv2: Specialty - Steelmaker (Steelmaking Efficiency +50%)"

Vondolph was highly concentrated, completely unaware of the news, but the bonus was already on his body.

Clang!

Each time the sparks were like elves, laughing and dancing around Vondolph.

The red-hot scythe seemed to be breathing, and with each touch with the forging hammer, it was telling Feng Dolph how to better train himself.

Vondolph was completely oblivious.

Start with the edge of the anvil and smooth the part that is close to the end of the handle but not sharpened.

Tap it, and the blade surface bulges into a piece.

Flip it over to the other side and level it down again against the edge of the anvil.

Strike this repeatedly, using a right-angled line to create a symmetrical cutting edge.

Then, using this symmetrical cutting surface as a reference, start from the tip of the knife and hammer the cutting edge all the way to the shank......

Feng Dolph suddenly thought: Can you start from the handle of the blade and knock it from the bottom to the top?

His instinctive feeling didn't work.

The central symmetrical cutting edge is at the shank, and it is easy to knock the freshly made symmetrical line crooked.

The tip of the knife is far away and is not easily affected, so it is best to start from the tip of the knife.

Vondolph, enlightened!

"Iron Field Enlightenment, Forge +50!"

Cool, put in the furnace to simmer red, forge the cutting edge and knife shape, and smooth the non-cutting surface......

Vondolph prepares the sickle, or samarium, to the point where it is almost finished.

After heat treatment, there is no need to use grinding equipment or belt grinding machine, and only a file can be used to complete the blade, which greatly saves the workload.

"Prepare for quenching."

Heat treatment is very important, through quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and it is also one of the core of the experience and technology of ancient blacksmiths.

There is no condition now, but it does not mean that Feng Dolph has no choice.

Feng Daofu pulled out the orange samarium knife with iron tongs, shook it in the air, and took out the magnet with his left hand.

The electrical program failed, but there were some results.

Feng Dolph put the magnetized cast iron on top of it, and used the magnet to judge the suitable quenching temperature.

In mild steel metal materials, the austenite structure only exists in the high temperature range above 727°C, which is the perfect quenching time.

And because when the Curie temperature of 770 °C is reached, paramagnetism will also be generated, and in this 727 °C ~ 770 °C range, the timing of only 43 °C needs to be controlled just right.

It is difficult, but it is much more accurate and objective than relying on visual and empirical judgment.

In a state of high concentration, the flame reflected in Feng Dolph's pupils seemed to come to life, as if he saw a microscopic metallographic world.

1 second ...... 2 seconds......

Multiply~

On the scythe of the cherry red burnt, the magnetism that emanates is just right!

"This is the moment!"

Vondolph slammed the samarium knife into the oil quenching barrel!

Zizi!

"Iron Field Enlightenment, Forge +50!"

"Forge Upgrades!"
