"When putting it in, not only should the mouth of the suffocated fire box be covered with pig iron plates, but the interface should also be sealed with soil."

"The sand is covered"

Standing in front of the stove, Shi Yiwen guided the craftsmen from time to time. Now, with his knowledge far beyond the times, he has completely formed a group with these craftsmen. He has only admired him, and he has only admired him.

The so-called furnace is a flame reflection heating furnace, which is specially built for toughening cast iron parts.

The parts of the newly made flintlock machine are installed in a box and the temperature is gradually increased after three or four days of heating, reaching about 1,000c. After the furnace is tightly sealed and cooled after three or four days of cooling, the castings become soft and can be cut and processed. This toughening treatment technology is commonly known as "stewing fire".

This process is long and seems simple, but when actually operating, there are some details that need to be paid attention to.

"Master Chen, please pay attention to the furnace flame. The color and brightness of the furnace are different, and the temperature is different."

Because some things cannot be explained clearly, Shi Yiwen deliberately clamped small silver pieces with iron pliers and placed them in different parts of the furnace. Because the melting point of pure silver is 960c, the flame brightness is observed according to the silver when it starts to melt.

"Master Chen, please pay attention to the silver, observe when it starts to melt, and then remember the color of the flame, and the temperature will be appropriate at this time."

The melting of silver was used to train workers to master the technology of judging the furnace temperature of the flame color, thereby controlling the temperature of the toughening treatment of the white-mouthed pig iron castings. This is what Shi Yiwen saw from a book. The method is very rustic, but it is very effective.

Although this treatment was performed for the first time, a few days later, a batch of flintlock castings that had been treated with black heart toughening were finally released.

Compared with others, Shi Yiwen undoubtedly looks forward to the final result more.

"Boss, look, it can be polished, this can"

When the apprentice combined small castings and was polished by a round mill, Zhang Sixi and Sun Zedong were all stunned. In this factory, too many things have subverted their understanding.

"This, that's what happened?"

The box that usually took more than an hour to come out was created, and in just a short while, it was created. This speed made Sun Zedong pick it up in surprise.

"Look, it seems that it's no worse than what we fight."

"No, the iron mouth is hard enough."

"This is pig iron, of course it is hard, tough on the outside and hard on the inside. This is a good thing."

In everyone's surprise, Zhang Sixi's thoughts sank again. Looking at the polished smooth and bright box surface, he suddenly felt that his skills were useless.

"Dong, boss, does this still require our skills?"

Looking up at the boss, Zhang Sixi opened her mouth, but finally didn't say it.

Shi Yiwen, who was about to urge them to conduct an experiment, saw Zhang Sixi's dullness and immediately understood what he was thinking, so he walked over to comfort him.

"Master Zhang, sometimes, some things can be used to use new methods, so you have to use new methods. Don't think that new methods will affect your money. Let's think about it from a different perspective. In the past, so many masters have only made so many parts in a day, but now they are cast so that the apprentice can use a steel file grinder to polish them, and then use tapping to tapping to make good wire. Do you think, how much more can we hit in the remaining time? Doesn't the more you hit together mean that you have made more? Of course, there will be more? Are you right?"

Looking at Zhang Sixi who hadn't tasted it, Shi Yiwen knew that he might not understand the key for a while. In fact, ancient craftsmen were good at craftsmen, but sometimes, they would resist some new technologies, just like the principle of hydraulic hammers is the same as that of water mills. Why did they use it to crush ores for thousands of years to process rice and grain, but no one used it to make iron.

To put it bluntly, the blacksmith who made a blacksmith himself was unwilling to do so. He was afraid that he would be taken away by a hydraulic hammer, because not every blacksmith lived near the river. Even if he lived by the river, he might not necessarily do this when he thought of it, because he was afraid that others would learn and he would lose his livelihood.

Sometimes they would rather put more effort into it because strength itself is a livelihood. Just like now, Zhang Sixi is full of resistance to the cast flintlock machine, because he feels that this thing may take away his livelihood.

When the new flintlock machine was combined and tried and hit hundreds of times, but no fragmentation occurred, the natural production process changed.

Just as Shi Yiwen was about to leave, Zhang Sixi suddenly asked.

"Owner, I just thought about it. If you save these jobs and use reed screws and other things, you can shoot several times more. You can almost 180 sets of flintlock machines this day, but our factory can only produce 50 barrels a day now. There are more than less tubes in this machine, and it will definitely not work."

Facing Zhang Sixi's inquiry, Shi Yiwen understood that he should have figured it out.

"This is simple, just add a few more boring machines, oh, by the way."

Looking at the workers present, Shi Yiwen had an idea and expressed his long-planned idea.

"If anyone of you can come up with ways to improve, such as speeding up the production of gun barrels and increasing the output of more than 10%, in the future, every time you produce a barrel in the factory, you will give you two cents."

"Take two cents aside!"

The workers in the factory all opened their eyes wide in shock. This was equivalent to drawing 10% of the commission. After all, the labor cost of a gun was 20 yuan.

"Our, what if it's like a butt flintlock bayonet and other things?"

"Same, 10% will be raised as a reward based on the wages. And this reward, as long as the factory uses your method, you will receive commissions in this proportion within ten years. Even if you encounter an accident or something, the money will be given to your family and children. The factory will never owe you a penny,"

After saying this, Shi Yiwen turned his head and said to Li Deyun, the manager of the factory next to him.

"Deyun, write down this rule and post it with other factory rules. In the future, this is the rule in our factory. Whoever invents new methods or new products to speed up production will give him the corresponding funds. This is the patent."

Nodding heavily, Shi Yiwen spoke out this long-simmering method. Although there are many mechanically processed books in the library, they are not necessarily suitable for this primitive and backward factory. Many technical accumulations were born from such factories. Now he only needs to give an appropriate mechanism and provide appropriate stimulation. He believes that as long as the motivation of these skilled craftsmen is stimulated, they will definitely surprise themselves.

"The boss's words are serious?"

Facing their questions, Shi Yiwen smiled.
