After they quickly returned to Lin'an County, the five friends visited the Dasong Hongshuixi Industrial Park on the same day. Pen "Fun" Pavilion www.biquge.info

Wu Dapeng and the three of them were made to orgasm by this feeling of being more than 20 years younger, and they felt that everything was a bunch of energy, and they had no idea of resting for a while in their hearts.

They had such good physical strength and energy when they were young, but how many brain-dead and idiotic behaviors did they do? How many times have you been deceived, and how many have you been deceived?

In retrospect, those contemporaries seem to be more deceitful than themselves......

Now it's really good, really, no one can deceive someone like them who has the physical strength of a young man and the mind of a middle-aged uncle.

Of course, they dare to guarantee that their level of intelligence and comprehension is above average, and they are people who can see through the phenomenon to see the essence.

They never listen to what others say, and they never look at other people's actions, they only look at the results.

It didn't turn out well, and you still said a fart? Acting a fart?

They don't argue with others, they don't observe their butts, they all look like they are miserable, and they think that they are living a better life, you have a fart in arguing with such a person?

But there are too many internal arguments, such as Wu Dapeng and Song Ziqiang.

In the industrial park, Wumao Song Ziqiang waved his hand and said: "Smear the yellow mud on the outside of these wooden houses, and cut some straw into the yellow mud, which can also prevent fire from the wind." ”

Wu Dapeng said: "What should I do if it rains?" It's better to plaster it with white ash ......"

"The yellow mud is wet, and if it's broken, wipe it again! Isn't the white ash also wet? ”

"The white ash is wet, and if it's broken, wipe it again! It's much less troublesome than yellow mud. ”

"Yellow mud!"

"White Ash!"

It's true that young people are prone to, and they are also enjoying the joy of.

Wanshida immediately jumped out to play a round and said, half white ash and half yellow mud, whoever proposed to find someone to do it.

Later, the place was really half yellow and half white, not to mention pretty good.

Song Ziqiang looked at the big Song technician students again, and said dissatisfiedly: "These boys you recruited are too weak......

Wu Dapeng put his hands behind his back and said, "Isn't it healthy to raise one?" The key is to learn our technique! ”

Song Ziqiang smiled and said, "Tell me, what kind of skills do you have?!" ”

Wu Dapeng really doesn't know any skills, but he will never be defeated.

He said, "Remember! A technician who does not know how to analyze social problems is an idiot...... I will teach them to analyze problems. ”

After both of them scolded each other for a, they went their own way.

Don't be uncommon to take care of him!

Those Great Song technician students were gathered just now, saying that they wanted to see the other three professors, all of whom had just come from Lin'an Mansion...... They looked up and found that these three professors were even more people with strong bodies, not only secretly shocked for this, but also overseas people were really strong!

At first, they were happy that they were hired by overseas merchants, and they were paid quite well.

The Great Song Dynasty government in this time and space is still very confident and has not fooled the common people into being xenophobic.

Their common people did not discriminate against overseas traders, even in inland counties.

Overseas merchants traveled around the Great Song Dynasty, and even settled down in the society of the Great Song Dynasty, and then married wives and had children.

Later, these migrant workers felt that they were different from the previous master's house, the food, clothing, and housing here were excellent, and it was a little weird, and they had to learn a lot of things, and they didn't like to calculate that weird number.

However, after those workshops are built, what kind of work they will do is something worth caring about.

Guo Ziren and Xiao Xiang were really a little scared, don't let them be responsible for adding ingredients to the biogas tank, it must smell bad.

The two of them didn't answer in class, pretending to be serious, hoping that Professor Wang would forget the arrangement he said casually.

Today, when everyone was gathered to see the three professors who had returned from afar, I thought to myself, I'm afraid that we have to start picking people.

They all held their chests and bellies high, trying to make a good impression on the professors.

Only Song Ziqiang patted this and pinched that alone, and he seemed to be a little dissatisfied.

Hearing Song Ziqiang give such a comment, Wang Defa was also a little dissatisfied, he was comparing them with the people in the world.

Wang Defa said: "You haven't seen that when they first came, they were all thin. ”

But no matter what, they still have a good starting point, but it's not good, and that's the only way to go.

Song Ziqiang could only nod in approval, and he said, "Okay, Wanshida, you come to help me, what should others do, what should they do." ”

Song Ziqiang put forward his requirements for the workplace in advance, and Zhang Guoan did them one by one.

He first ran to check on the construction of the workshop, which would be his machine shop.

This so-called machine shop, in appearance, is a little taller than the other houses, with high windows, light and ventilation, and a little farther away from other workshops.

After he entered, he first observed the ground, which should have dug a one-meter-and-a-half pit according to his request, then filled it with stones, and then backfilled it with earth and paved it with stone slabs.

In this way, the floor of this wooden house has a certain degree of earthquake resistance.

In the middle of his workshop, there is also a large rock, which is a granite stone unique to the area, which has been polished by the stonemasons here to a square shape according to his prior request, and the countertop now looks very flat.

He pressed his palm against the countertop and drew a large triangle, which didn't feel too flat, and he had to deal with it again.

This will be the workbench of his machine tool in the style of Song Ziqiang, which should have been cast iron, but that is too troublesome, not that I am afraid of internal stress problems, where does it need to be precise to this extent.

In this crossing, they were even more careful, and they all regretted that they had brought a broken three-wheeled motorcycle before, and with that energy share, they could bring more useful things, even if they wore them one more time.

But there is no way, I was inexperienced when I first crossed.

So let's just use it to the fullest.

At that time, Song Ziqiang could only use the material of this 175cc three-wheeled forward motorcycle.

The countertop, which he designed in granite stone, then punched holes in it fixed the machine.

The power source of the machine tool can only use the 175cc single-cylinder diesel engine, but when it comes to use, he should pay attention to the stability of the output power.

The power take-off system of the lathe is directly disassembled from the car.

In his words, as long as he can turn up, he is not afraid.

In the past, Wanshida also expressed concern about his design, saying: "Can you ensure the accuracy of the workpiece?" ”

Song Ziqiang said confidently at that time: "What are people for? That's enough for my feel. ”

Wanshida was persuaded by him, and thinking about it, the accuracy requirements of this era will not be too high.

He can't solve it with only knives, so he can only bring this.

As for fixing screws, linkage screws, and the like, he tried to disassemble the car as much as possible.

He was ready to even make the chuck himself.

Wanshida was a little scared and said: "Hadron, don't save this attachment, you can't waste much energy, right?" That is, it was thrown out in the flying, and it would be dead! ”

Song Ziqiang said confidently at that time: "You haven't seen my ability to chisel, right?" Pig iron casting, chiseling and hand grinding...... Just wait and see. ”

Wan Shida could only retreat at that time, saying: "Count you ruthless!" I see how you can keep the axis concentric......"

Song Ziqiang said hesitantly, saying: "This is unacceptable, there are no standard parts, and they are all used to deal with." Which person who comes out of a private machine shop will not operate savagely? ”

Knives can only be brought, abrasives can only be brought, and of course, there are some related accessories, all of which are tools and supplies that cannot be solved for a while.

He also designed a vertical machine tool with the axle as the main body of the bed, and then the frame was manually drilled to make holes.

Wanshida really understood his train of thought, this is the future, he is preparing to deal with the hardwood.

Song Ziqiang said: "By the way, can we afford to play with hardware artifacts now?" Isn't it just to help Lao Zhang build a few workshops...... This has already scared the ancients to death. ”

Zhang Guoan has also accumulated some hardwood materials in the past two months, of which the hardest is red sandalwood.

This was originally a few dead items in the warehouse, a flower stand, a screen, a few tables and chairs, and the largest was a wooden bed.

Rosewood is not cheap in this time and space.

The ancient Chinese knowledge and use of red sandalwood is said to have begun at the end of the Eastern Han Dynasty. The earliest use of red sandalwood in the ancient Chinese court is documented and should be in the Tang Dynasty. According to records: Tang Wu Houzhu a white parrot, named Xueyi, sexual intelligence, can recite a volume of the Heart Sutra. After love, store it in a golden cage, and never leave the left and right...... Later, the pet bird unfortunately died, Wu Zetian was extremely sad, and the special craftsman made a small and exquisite rosewood coffin and buried the white parrot in the Royal Flower Garden.

It can be seen that in the Tang Dynasty, skilled craftsmen were able to use red sandalwood to create such exquisite utensils.

A rosewood inlaid luodian qin in the collection of Shosoin Temple in Japan is said to be a relic of the Tang Dynasty.

Otherwise, it took so long to get these hardwoods.

Song Ziqiang went to the so-called material warehouse to take a look, and his eyes turned red all of a sudden, and his hair suddenly got up, and said: "It's really dead, how much can this bed sell for if it is carried over!" Look at the pattern...... Don't be ignorant of relics! ”

Wan Shida immediately patted him on the shoulder, stroked his hair for him, and said: "You calculate, people in that world prefer stones, besides, there are still few rosewood products in this time and space, but it is not unusual, don't ...... like this."

This trick is so good, Song Ziqiang went down at that time.

So, the two of them began to disassemble the car seriously, and a small part could not be wasted, and there was nothing to be found in this car!

They all have the necessary tools, and they can't do without this.

In the work of dismantling the car, neither of them used others, but they didn't dare to dismantle it indiscriminately, a screw can have its effect.

Dasong technical engineering students continue to attend classes.

The content is still a cumbersome calculation, adding and subtracting, multiplying and removing, and finally Hou Dongfang was a little annoyed and said: "Even if you strike iron, you don't need to be so tired, right?" ”

Professor Zhang Guoan said with a smile: "But this knowledge can be used in iron strike------ I can use a ruler to measure the weight of iron, can you?" ”

Hou Dongfang really struck the iron, he stared at the big eyes and said, "How can it?!" ”

Professor Zhang Guoan still smiled and said: "After class, I will give you some money, you can go to the blacksmith shop to buy a piece of iron and come back, I will demonstrate it to everyone, okay?" ”

The crowd burst into laughter.

Professor Zhang Guoan immediately became serious again, and said: "But now continue to calculate the problem, carefully find out the area of the triangle, and carefully measure their angles!" If one of them can't be completed, the demo will be cancelled! ”

Everyone immediately became serious, and the anger of boredom was swept away.

After class, Hou Dongfang was indeed in a hurry, took the money, and ran towards the blacksmith shop in the county.

He did strike iron, but in the shop, he used a scale to weigh iron, how can he use a ruler to measure it?

He ran fast on his feet again.

There are many statements about the iron production of the entire Song Dynasty, and the difference is not small, and when they are in that world, of course, they have to check some information and analyze it carefully.

According to ancient official sources, the Song Dynasty appears to have produced only a few thousand tons of iron per year. Obviously, this official information is incomplete, some of which will not be included in the statistics, and some of the products produced in private businesses may not be added.

According to history, since the 3rd year of Song Xining (1069), the imperial court has set up 26 coinage prisons throughout the country, with more than 5 million copper coins and more than 800,000 iron coins, which has increased in the Southern Song Dynasty.

The iron money cast in the Song Dynasty was a large iron coin of 25.5 Song Jin (about 15.3 kilograms), which was 13,000 tons based on 850,000 guan.

Of course, the iron money of the Song Dynasty added a small amount of tin, which also required about 12,000 tons of iron, which is only the medium-term level, of course, maybe these are not all big money, but later the amount of iron money increased a lot, so the annual iron consumption of iron money in the middle and late Northern Song Dynasty was at least 12,000 tons.

The Song Dynasty had the world's most and strongest heavy infantry in the Northern Song Dynasty, with a weight of 40~50kg per person and about 35~40kg of iron.

At that time, it was not an exaggeration to say that the forbidden army had more than 40kg of iron per person, and there would be a lot less box army.

The army of the Northern Song Dynasty was uncertain, but in the later period, there were about 800,000 forbidden troops, at least 500,000 box troops, and the amount of iron should be at least 45,000 tons.

And the most important thing is the people, the Song Dynasty was relatively wealthy, and the iron output was very large, so the common people must have a large number of iron tools in their hands, merchants have scales, scissors, etc., and farmers have iron farm tools, such as quyuan plows.

The most important thing is that there must be iron pots, kitchen knives, etc., an iron pot has 15kg, just to calculate the ancient technology, Quyuan plough and other agricultural tools with a lot of iron, the average down to at least 30kg per household, at the end of the Northern Song Dynasty there are 21 million households, about 630,000 tons of ownership, 20 years for a change is 31,500 tons per year, and 1% of the richest class per capita will be more than ten times the per capita of the common people (about 3,500), which has 35,000 tons of annual consumption.

The above total has an annual consumption of 50,000 tons, which is a very conservative calculation, and the consumption is about equal to the output, so the bottom line of iron production (including steel) in the middle and late Northern Song Dynasty is 50,000 tons.

Therefore, as long as there are enough skilled craftsmen, it is completely possible to produce more steel, and the key depends on demand, and it is clear that the Song Dynasty met these conditions.

Later, in the Ming Dynasty, there was a record that the annual output of iron was 97 million catties, which was more than 50,000 tons.

For a large country with a population of about 200 million, 50,000 tons is not much at all, which is very suitable as the lower limit, and that Yuan Qing is far from catching up at this point.

The lower limit is 50,000 tons, and as for the upper limit, everyone can't think of it, and the irresponsible calculation is about 150,000 tons.

However, the per capita iron of the Song Dynasty is likely to be much higher than theirs, and the increase in iron coins is also very large, and the consumption during the war is also very large, even if it is less than 150,000 tons.

There are seven or eight blacksmith shops in a county town of Lin'an, not counting the small blacksmith shops scattered in the surrounding countryside.

Even during this period, there were mobile blacksmiths, and the master and apprentice pushed wheelbarrows to some remote mountain villages to make up for it.
