Bright Sword Military System

Chapter 33 Silver Dollars
After Zhang Wanhe said this, Wang Xuexin found out that this is really the case.

Many of the equipment of the Eighth Route Army could not be developed or had quality problems. In fact, they were all stuck by the raw material "iron".

The most typical example is the grenade. In the words of Li Yunlong, it is: "Our grenade explodes in two halves. This thing is a net delay on the battlefield!".

This is true. In fact, it is good to blow in half. Some grenades burst into a small gap after the explosion, just like a broken jar.

In the battle, sometimes the grenade was thrown at the devil's feet, and the devil was blown into the smoke with a "bang", but the devil did nothing but cough a few times and his face was blackened.

However, since the Eighth Route Army had no equipment, the troops still had to use this grenade.

Hence the words of Li Yunlong: "A good plaster is the one that can pull out the pus, something is better than nothing".

The reason is that the quality of the iron is too poor to be processed further... Once it is processed, it is either broken or cracked, and you can't use it.

If the "white heart toughening technology" is used to improve the quality of iron, does that mean that the grenade can be grooved and its quality can be improved to a level?

In addition, can landmines also be upgraded to a level?
In addition, there are bullet casings, don't you need to pick them up on the battlefield and "reload" them?

Later, Wang Xuexin realized that the first two are feasible, and the processing of bullet casings has higher requirements on the quality of iron, and the white heart toughening technology is still insufficient.

The imitation of the grenade can be said to be the top priority of the arsenal at present, and even Zhang Wanhe did not dare to be negligent.

As a result, several directors, including Zhang Wanhe, basically put their business aside and gave priority to artillery and shells.

Sand casting is a quicker step.

In fact, if you reach the formal production steps, you still have to be cautious, because the size of the shell should match the caliber of the artillery, otherwise it will not fit if it is too large, and the sealing will not affect the range if it is too small.

However, the main purpose at this time is to verify whether "toughening" is feasible, so there is no requirement in this regard for the time being. After a rough design, more than [-] shell casings were made in the second branch.

Then the shell casings were arranged one by one in the square furnace, covered with fine sand, and a problem was encountered when preparing to ignite.

"How do we know when the furnace temperature reaches 950 degrees?" Hardware asked: "You can't try it with your hands to see if the temperature is 900 degrees or 1000 degrees?"

"Observe the color of the fire." Zhang Ruozhong, director of the second branch, has some experience in this area. He replied: "The combination of color and brightness can roughly judge the furnace temperature, but it must be an experienced master. There are several in the second branch."

"Then what are you still doing?" Zhang Wanhe said, "Go and transfer all these old masters."

Zhang Ruozhong responded and arranged for someone to call.

Su Xin has doubts about this: "Director, it's not that I don't believe these old masters. There must be errors in people's perception of fire. The same fire makes each master look different, not to mention that there are only so many old masters..."

"It's easy to handle!" Zhang Wanhe said anxiously: "Let the old master bring a few apprentices, and also, take a small notebook and write down all the key points such as brightness and color changes. If anyone keeps a hand, I, Zhang Wanhe, will follow me. He's not done!"

No wonder Zhang Wanhe would say that, many of the older blacksmiths are passed down from generation to generation, relying on experience, more like a folk craft than industrial technology.

But the younger generation of technicians, especially Su Xin, have a different way of thinking.

What they want is instruments, precision, and data... not just a wave of the old master's hand: "I have walked more bridges than you have walked, and I have eaten more salt than you have eaten, listen. I was right!".

When everyone was hesitating, Wang Xuexin's words solved the problem.

"Hey... I said." Wang Xuexin: "Comrade Su Xin didn't pay back the melting point of this melting point just now. Wouldn't it be better to find something with a melting point of 950 degrees and put it in it?"

"That's right!" Hardware waved his fist heavily: "Put something with a melting point of about 950 degrees in it. If it melts, it means the temperature has reached. If it doesn't melt, it means it needs to be heated. Good way!"

"Why didn't we think of it?" Zhang Ruozhong stared blankly at Wang Xuexin, then turned to Zhang Wanhe and asked, "Director, then... do we still need an old master?"

"Yes, why not?" Zhang Wanhe replied angrily: "Master wants it, and Comrade Wang Xuexin's method is also required."

Then Zhang Wanhe took advantage of Wang Xuexin to help the workers to fill the sand, and pointed his finger around the director of his subordinates, and criticized in a low voice:
"All of you, ah! This is the director, the technicians, and the top students! Isn't it shameful?"

"Everyone in Xiaodongbei who is a soldier can come up with a solution. But you can't take this matter."

"If this spreads out... Where can we put the face of our arsenal?"

"At that time, you will all stop doing it, and let Xiaodongbei come?"

Su Xin blinked and looked at Wang Xuexin, secretly saying that this little Northeast is really clever!
It would be fine to say that he had seen devils use this technique before, so he knew more, but the method of using melting point to measure temperature... is not something that ordinary people can think of!

At least she, a top student, didn't expect it for a while.

Seeing Wang Xuexin walking back, Zhang Wanhe hurriedly closed his mouth, then "um," cleared his throat, and turned the volume back to normal as if he was okay: "Um, um... what's the melting point of 950 degrees? "

Su Xin answered without thinking: "Silver, 961.78 degrees!"

Yo, it's all accurate to the decimal point.

Wang Xuexin admired for a while, as expected of a talented student from Fudan University, he could bear it all.

Later, Wang Xuexin learned that this was actually Su Xin's specialty, and it was one of the reasons why Zhang Wanhe let Su Xin manage the third factory.

Zhang Wanhe did not hesitate, and immediately ordered: "Find a few silver dollars, act fast!"

Although the Eighth Route Army was poor, they still had a few silver dollars.

After finding it, divide the silver dollar into several small pieces and place them in different positions in the furnace... This is to ensure that the temperature in different positions in the furnace is consistent.

Next is to heat it for a long time while being careful not to let the silver block melt.

But that's easier said than done.

Because this square furnace has to burn day and night, it is necessary to always observe whether the silver dollars in the injection furnace are melting. If it is accidentally melted, not only should the temperature be lowered, but silver must be added to the furnace to continue the observation.

Zhang Wanhe jokingly said, this is like the Taishang Laojun refining elixir.

Zhang Wanhe divided the manpower into three batches to take turns to take care of them, and each batch had at least one teacher and one director.

The old master is used to watch the fire, and the director is directly responsible for the fire and can mobilize enough manpower to respond at any time.

The extra director is responsible for the normal operation of the arsenal.

In fact, it was three batches. Zhang Wanhe basically hadn't slept in the past few days. From time to time, he walked around in front of the stove, rubbing his hands as he walked.

Su Xin secretly told Wang Xuexin: "I have been at the arsenal for more than half a year, and I have never seen the factory manager so nervous."

　To explain the problem that silver dollar is an alloy, the melting point of the alloy is slightly lower than that of silver. The article requires 950 degrees, while the melting point of silver is 961 degrees. A slightly lower melting point does not affect temperature control.In addition: All the details of the white heart toughening and black heart toughening in the text come from the real process of the Eighth Route Army toughening white iron
