As soon as Old Wei left, Su Xin hurriedly ran in with her back legs.
"Quick!" Su Xin pulled Wang Xuexin out without saying a word: "The axle is here, the factory director asked you to go there if it's empty!"
Wang Xuexin complained in his heart, you are dragging people on the road, and you still ask if you are free?
When I arrived at the first branch factory, I saw Zhang Wanhe and several directors there. There were three wheel axles in the open space. The hardware measured them and reported: "Diameter 150mm, length 1489mm..." (Japanese Railway uses narrow pitch 1067mm, wheel axles
slightly longer than a railroad track)
Zhang Wanhe excitedly said to Wang Xuexin: "I heard that this axle can be used for four years. It was replaced after just over a month of use. It is suitable in all aspects, but I am worried about the drilling problem!"
"Director, let's try it!" Wu Jin said.
"Let's try, what else can we do?" Zhang Wanhe pretended to be relaxed: "We don't expect it to work anyway!"
There is a saying that the greater the hope, the greater the disappointment. Zhang Wanhe feels that if there is no hope, there will be no disappointment.
But even he himself knew that this was just nonsense to lie to himself.
When the wheel axis didn't come these days, he called Li Yunlong every day, sometimes twice a day:
"I'm talking about Lao Li! You really have to take care of me this time! Don't let the enemy seize the wheel axle on the road!"
"This thing is just scrap metal in the eyes of others, but it's a treasure in our eyes! There's nothing careless about it!"
"Chengcheng, of course I will miss you if I have something good! What is our relationship?"
He, Zhang Wanhe, had never begged someone so humbly before, and this time he almost fell to his knees in front of Li Yunlong.
"Hey..." Zhang Wanhe watched several people lift the wheel axle onto the machine tool, and shouted nervously: "Be gentle, don't knock it!"
When the hardware was fixing the axle on the machine tool, Su Xin raised her head towards the drill bit at the other end and introduced: "That's the twist drill we processed, thanks to the method you mentioned about modifying the bellows!"
Wang Xuexin looked along Su Xin's gaze, and sure enough he saw a spirally twisted drill bit like a twist, about sixty centimeters long.
Wang Xuexin thought that Su Xin and others should cut the long drill pipe into several sections so that they could continue drilling one section after another.
Hardware put some oil on the drill bit, and then turned his attention to Zhang Wanhe.
Zhang Wanhe nodded, and as soon as the hardware pressed the switch, the twist drill started spinning quickly.
Hardware carefully moved the drill bit towards the wheel shaft, and with a harsh sound of metal turning, the wheel shaft slowly sank into a pit.
After a while, Wu Jin stopped and shouted excitedly: "It can be done, but it's a little slow. The deeper you hit, the more careful you have to be. After a while, the slag will be poured out, and you have to cool down and refuel. It may take more than ten days, we should
First, shorten the axle to make it easier to hit!"
The crowd immediately burst into cheers.
Zhang Wanhe pretended to be there and shouted: "What are you excited about? You haven't even written your horoscope yet! You won't know if there is any problem until you make it and fire a few rounds. Don't get too happy too early!"
Zhang Wanhe said this, but he knew in his heart that the steel of the train axle was fine and could be drilled, and there were no other technical difficulties.
This is a cannon!
The Eighth Route Army is about to have its first artillery piece!
Many more can be made in the future...
Zhang Wanhe was so excited that he staggered and almost fell down, which made everyone feel funny.
Zhang Wanhe ignored others, only waved to Wang Xuexin, pulled him aside, and said in a low voice: "Xiao Wang, the superiors highly praised our arsenal for active production and the spirit and achievements of inventing new weapons, especially the toughness of steel.
Chemical technology, this technology has spread to the entire army, bringing our army's equipment to a new level as a whole. However, because it is confidential, the results in this area will not be announced to the public. Let's talk about it internally. I hope you can understand!"
"You must understand!" Wang Xuexin replied: "Don't worry, director, I understand this principle and don't care about the name."
Wang Xuexin really understands.
Because if the entire army announced a commendation, the Japanese spies would immediately target Wang Xuexin, and even guess the location of the arsenal based on Wang Xuexin's whereabouts.
At that time, whether it is a strong attack, assassination, or another special agent team is dispatched... it will not please you anyway!
This is what people often say: "People are afraid of being famous, but pigs are afraid of being strong." So we still have to keep a low profile.
Zhang Wanhe nodded and said: "As long as you understand! In addition, I have some good news for you. Because we are trial-producing artillery, our superiors plan to allocate smokeless gunpowder to us in a monthly ration, and are also considering setting up a chemical branch in our arsenal.
Factory. If the artillery can be built, I don’t think this chemical branch factory will be gone!"
Wang Xue understood what Zhang Wanhe meant.
If the Chief of Ordnance can produce artillery, then of course he must use smokeless gunpowder that burns more fully in order for the artillery to be more powerful and last longer!
Otherwise, you have to clean the barrel after firing a few rounds, which will definitely affect the combat effectiveness. (When firing reloaded bullets, there is a problem of cleaning the barrel, otherwise it is easy to explode the chamber, but reloading bullets also has the reason why the rifling is severely worn)
So the gunpowder came with the artillery.
What surprised Wang Xuexin was...
"Our army can actually build a chemical factory to produce smokeless gunpowder?" Wang Xuexin asked.
Zhang Wanhe nodded: "I just knew it, it was hidden deep enough!"
Later, Wang Xuexin learned that this was not actually "deeply hidden", but that the chemical plant had just produced the first batch of nitric acid and used it as the basis to produce smokeless gunpowder (December 1940).
This chemical plant is located in Da'angou, Yizhong, code-named "Pig".
The reason why it is called "Pig" is because the sulfuric acid and nitric acid are produced using the local method of "cylindrical tower method", which is to use ordinary people's large vats for distillation. An acid-resistant lead pipe is added to the side of the vat, which looks like
Pig nose.
At this time, after several years of trying and numerous failures, they finally succeeded in producing sulfuric acid, the mother of gunpowder, using the third generation "cylinder tower".
However, the output is very low. If it weren't for the fact that the Lujiagou Arsenal could produce smokeless gunpowder in urgent need of artillery, it would never have happened!
Therefore, the wisdom of the masses is infinite. If you invent something here and innovate something there, it will be a great achievement if you put them all together.
That’s fine. Wang Xuexin had previously thought about whether to buy smokeless gunpowder technology from the system...
But at first I thought that the black powder was barely usable, and what was more urgent was to solve the problem. The gunpowder could be put away first.
Secondly, the target of the chemical plant is too large and it is easy to be exposed... Chemical acid production will inevitably produce pollution, and the pungent smell can be smelled from a distance.
Therefore, the matter was delayed again and again.
Unexpectedly, another place was renovated, and Wang Xuexin also saved a sum of military currency.
