Director Su of the Mingren Hand Forging Workshop of the Red Star Forging Factory, his eyes lit up when he saw this thing, and he hurriedly stepped forward and said, "Director Mo, can you let the little one try it himself?" ”

The ink director of the Red Star Forge said with a smile: "Of course, practice makes true knowledge!" ”

After squatting and shaking a few times, Director Su slowly thought about it: "This object is full of wind, there is no noise in the shaking, and the operation is very smooth - this object can be blown uninterrupted, and it is not like a hand-pulled bellows, which appears without wind between a push and a pull, so that the flame is long and short, and the firepower will always be temporarily weakened - so that the firepower is sufficient, and the charcoal is relatively saved-but I don't know how to do it without hindrance when turning?" ”

Director Mojing smiled. He made it himself.

Referring to the model of the electric hair dryer used for cooking in the canteen, the director of Mojing used simple tools to glue and plane the wooden planks to make the two walls of the bellows, and then used thin wooden boards to wrap a circle along the edges of the two walls of the parallel bellows, and nailed them firmly, so as to make the body part of the wooden hand-cranked hair dryer, which has air inlets and air outlets, and is equipped with wind wheels that generate wind power when shaking.

There are 6 blades mounted on the wind wheel, and the blades are directly punched with a stamping machine. In order to make the wind wheel durable and have low resistance, the director of Mojing installed the spare bearings of the two-wheeled vehicle at both ends of the wind wheel shaft, and then fixed the wind wheel with a frame, and then fixed the hand wheel that drove the wind wheel to rotate to the right of the upper part of the body.

The hand-cranked wheel is equipped with a crank handle on the outside, and there is a groove around it, so that it can avoid slipping when shaking after the belt is installed.

He installed the axle of the hand-cranked wheel in a section of iron pipe equal to the width of the body, and the bearings were also installed at both ends, and the iron pipe and the hand-cranked wheel could change direction at the same time, and could be turned around and installed on the other side of the bellows body, so that the direction could be changed at any time to blow the air.

Finally, all the parts are brushed with wood tar, dried and attached to a belt made of deerskin, and you're done.

At that time, the first hand blower was made in the Red Star Wood Products Factory, borrowed from their tools.

Wang Baoshan, director of Hongxing Wood Products Factory, looked at it at the time and said happily: "This thing is good, you designed it?" ”

"No, this blower was made by my father, and my blacksmith's furnace used it back then—and I've changed it a little more now with the electric blower, when my father used blades cut out of broken chimney skins little by little with iron scissors—"

"What a clever hand for our fathers—" Director Wang Baoshan also seemed to fall silent, and he seemed to think of his father—

"Hehe, but I'm doing better now than he was, and my old father will be glad to know about it—even if it's a thing that has fallen behind home."

"Yes, yes, we're doing a lot better than our fathers now – why don't we provide electric blowers to the Ming people? Improving their production efficiency has also indirectly helped us a lot? ”

Director Mojing thought for a while and said: "I also thought about this problem, and later understood the difficulties of the Hantang Group. If you go to the Stirling steam engine, you have to send someone to maintain it, but it will waste technicians. Forget it, let them get it themselves, it's better than nothing-"

"That's right, Lao Mo, your thoughts also remind me, let's treat them as if it's better than nothing, this mentality is good-"

The remaining two are even more troublesome, after the director of Mojing left the relevant accessories, Wang Baoshan, the director of the factory, said that after work, he can do it in his spare time.

Looking at the hand-cranked blower, every Ming blacksmith's eyes were bright, how could they not know in their hearts, this object is really useful, labor-saving, and the wind lasts -

The director of Mojing took them to visit the charcoal warehouse - a large wooden box full of machine-made charcoal, which really shocked the Ming blacksmiths, what charcoal can be fired exactly the same?! Could it be that the Han Group has carefully selected their best charcoal for me to use?! That's also impossible—

Director Su stepped forward quickly, grabbed two pieces of charcoal, and knocked on them. The charcoal actually made a sonorous sound like an iron tool - the best hard charcoal!

I grabbed two more pieces and knocked them on each other, and it was still like this—

Mojing factory director said with a smile: "Charcoal can be used casually, don't waste materials, and the completion of the work requirements is the first important thing - in two months, we can completely use firewood and coal." ”

The people of Zhongming gasped in their hearts, looking at the appearance of the director of the ink factory, how much charcoal is such a high-grade - what is the firewood and coal that is being said? !

The iron ingot, they glanced at it, and no longer paid attention to it, and when they looked at the shape, they knew that it was from Foshan—

The anvil, designed according to the modern standard shape, pleased the smiths, and they began to whisper, and there were many ways to use sharp corners, convex grooves, and flat places, and the more they spoke, the louder they became.

At that time, Mojingchang happily closed his mouth, and that's fine, the gong doesn't need to be hammered - you can explore it slowly.

Since then, the clanging and clanging sounds of the Red Star Forging Factory have formed a main theme, not to mention, occasionally listening, it seems to cooperate well.

When there is nothing to do, Director Li Ziqiang, like Director Mojing, likes to go here to take a look.

A vivid performance of ancient hand-forging skills!

Director Su held the long iron tongs in his left hand and kept turning the iron in the furnace. He quickly pulled out the red piece of iron and placed it on the anvil. The other two smiths tensed their muscles and slammed their hammers at the anvils. The sparks were short-lived, and when they landed, they turned into black iron filings.

Director Su's eyes were blazing, his dark arm muscles were bulging, and the green tendons on his temples were prominent.

The small hammer he held in his right hand and the big hammers of the other two Ming blacksmiths flew up and down, one after another, making arcs and beating rhythms, like beautiful country music.

He put the preliminarily formed iron back into the furnace, heated it to soften, and then put it on the anvil and beat it in order to improve it.

The man in charge of shaking the blower immediately quickened the pace, and the charcoal flame was almost a foot high—

After taking out the iron tools again, Director Su held a small hammer in his right hand, sometimes hitting lightly, sometimes hitting hard, dancing up and down, rising and falling in an orderly manner, like an orchestra conductor. The two Ming blacksmiths holding the sledgehammer are shirtless, wearing a canvas belly pocket provided by the Han Tang Group on their chests, and their feet are covered with canvas shoe covers, draped with might, just like a warrior in a good frame, waving their arms, picking up the sledgehammer, staggering and beating, fast or slow, light or heavy, just right.

The sound of these Ming people striking iron has a strong sense of rhythm.

For a while, "jingle, ding, ding, ding", sparks splashed and sounded pleasant. In a short time, a hoe was formed—

The cycad inserts the finished iron into the water tank and quenches - the purpose of quenching is to make the supercooled austenite of steel undergo martensite or bainite transformation to obtain martensite or bainite structure, so as to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel.

The fiery red iron made a sound of "bang" when it was drenched in water, strings of water bubbles rose from the water, and the fishy sweet smell rose in the big work shed.

Director Li Ziqiang said to the director of Mojing: "Is this time and space only this kind of single-liquid quenching (zhan) fire? ”

"Dipping" is the industry term of quenching process, which originated from the method of process treatment, because quenching is to dip the hot workpiece heated to a certain degree dù into the medium to meet the requirements. However, it is not explained in the ci hai, only that there is quenching (cui confusion), which should be so, which causes many liberal arts students to always mispronounce it.

"Yes, this is the only way to do it in both the East and the West, and the other single liquid they use is animal fat. Just like you said, as soon as they happen to use the right steel, and they happen to dip it in the water with high salt content, it is very likely that there will be a sharp weapon in the world, and they will call it some kind of mysterious ** - hehe. ”

Director Mojing admired Director Li Ziqiang's remarks very much in his heart, and thought that he said the voice of the science and engineering students.

The two of them saw Director Su and another Ming blacksmith holding the crucible with long tongs, and drizzled molten pig iron on the mouth of the hoe arranged in a row, which was very fast, and then immediately quenched.

This technology is to use pig iron molten iron to make the surface carburizer of the cutting edge of wrought iron agricultural tools, this layer of surface carburizer has the properties of high carbon steel, after drenching, plus quenching technology, so it can be strong - worn, and then drenched.

Its ratio should be one pound of hoe and three coins of molten iron. Unfortunately, it is only suitable for small farm tools.

The two looked at each other and smiled, this is an extremely clever choice under the smallholder economy, although it is not as important as the promotion of forged farming tools and wrought iron steel-bladed farming tools, but it is inexpensive and has a wide range of applications.

Both of them had seen the use of this method to handle farm tools as children. Now I see the ancestor of this method, and both of them have a little emotion.

These craftsmen are completely qualified and competent!

"Director Mo, have their labor insurance benefits been arranged?"

"Whatever we eat and drink in the temporary dormitory, they do the same - the big wooden barrel also fills them with salt soda - but they can really eat rice, every meal is twice as much as ours!"

"Oh, there's no supply of fish?"

"It's supplied, I think the main reason is that their living habits haven't changed-"

"Don't be afraid, it'll be fine after a long time - let's go to your office and discuss it."

The two left together. They also have to discuss the next step of the exhibition plan, whether to increase or reduce, it is still unknown.

Planning, sometimes it's meant to change.

The blacksmith seemed relieved to see the two bystanders gone.

These people from the Hantang Group are really powerful, standing there, it always makes people feel pressure, although they have a good attitude towards us and others-

On that day, the director of the ink factory led them to the stamping workshop to see, when they saw it, they knew why there was always a loud noise, it turned out to be a large object made of stainless steel, only to see that it easily lifted hundreds of pounds of large iron, and smashed it into the steel below, just a few strokes, the steel was formed-

And the object that creaks and makes people's teeth ache, and easily cuts through the steel plate—

With the help of divine power?!

At that time, Director Mojing said lightly: "Electricity, you will use them sooner or later, but now is not the time, let's take our time-"
