The most important thing about an artillery is the barrel. The anti-tank gun is different from other artillery. Its requirement is that the higher the muzzle velocity, the better. This makes the wear on the barrel of the anti-tank gun extremely high. Once the barrel of this anti-tank gun is worn
If it is serious, it must be replaced, otherwise the accuracy will be seriously affected. This has a fatal impact on the gunner who needs to accurately hit the tank that may be moving.
Although the amount of steel produced by the Border Steel Plant continues to increase, it is still difficult to produce special materials such as gun steel. Gun steel needs to have extraordinary high temperature resistance, excellent strength and excellent toughness.
At the same time, the cost factor of mass production of artillery must also be fully considered. Modern artillery barrel materials are all made of alloy steel.
Medium carbon nickel-chromium platinum alloy steel is often used.
A small amount of vanadium was also added to make modified steel. However, in terms of resources, China is a country seriously short of nickel. Later, it was Jiang Cheng who brought some rare earth minerals from later generations and added them to steel manufacturing to solve the problem of gun steel production.
Song Wu watched nervously as the valuable gun barrel embryo came to the large drilling machine. This is one of the most important steps in gun barrel processing, drilling.
An old worker from Taiyuan Artillery Factory nervously operated the machine. With the fire blazing, a prefabricated hole was completed. Then, the barrel came to a huge boring machine. This time the master was from the Czech Republic.
The Jewish worker and several Chinese workers carefully observed his movements beside him. The delicate and difficult part of deep hole processing lies in the "deep". During the deep hole processing process, the operator cannot directly observe the cutting and other processes.
At the same time, it is also necessary to ensure that the processing reaches a high degree of accuracy.
Moreover, slender pipe fittings are also prone to bending and deformation during processing.
Therefore, the processing is extremely difficult. Since the processing quality of the inner bore of the barrel is closely related to the shooting accuracy, lifespan, and safety of the entire artillery, the requirements for dimensional tolerance, curvature, roughness, etc. after processing are extremely high. It can be said that
Deep hole processing is a prominent feature of artillery manufacturing technology that is different from ordinary mechanical manufacturing. This kind of technology is still lacking among workers in Yan'an. In order to succeed in the experiment, this time the operator was an old man who had worked in the Czech artillery factory.
Worker.
Slowly, the drill bit got deeper and deeper. The Jew squinted his eyes and observed carefully. After a while, he said in broken Chinese, "Okay, this, that's it." The small notebooks of several workers nearby were already filled with notes.
What they think are the key points of operation.
Then, the gun barrel went through finishing and self-tightening processes and then came to the assembly stage.
Components from several other production lines were also received from the assembly line in turn, and a 37 anti-tank gun was produced. At this time, the day had passed. Everyone's stomachs were growling, but no one wanted to eat.
Looking at the shining 37 cannon, Song Wu touched it excitedly and said, "Okay, that's it. Our production line is well deployed. Let's go test the cannon."
Not feeling tired, everyone took advantage of the darkness, using horses and cannons to arrive at the testing site, where an iron plate was erected.
"Let's try the original German artillery shells first, and then try our imitation artillery shells to see if there is any difference." Zhu Yusheng suggested.
"Okay, this way you can test both our artillery and the quality of our shells, killing two birds with one stone." Song Wu said in agreement.
The anti-tank gun was made by workers, so how to use it was not difficult for them. They quickly debugged the gun. For safety reasons, everyone hid in the bunker. The match rope was lengthened into the bunker, and then they suddenly fired
pull.
"Boom" The huge air pressure caused by the combustion of the primer pushed the cannonball violently out. The rifling in the barrel caused the cannonball to continuously rotate during advancement to enhance the accuracy of the cannonball. Everyone nervously ran to the side of the cannon.
"It didn't explode, it didn't explode, our cannon didn't explode!!" After observing carefully with a flashlight, Zhu Yusheng hugged Song Wu excitedly and wanted to kiss him. Song Wu was so frightened that he covered Zhu Yusheng's mouth tightly, "Wait a minute,
It’s just one shot now, it’s going to take a few more shots!”
"Yes, yes, you are right." Only then did Zhu Yusheng realize that he was a little too excited.
One shot, two shots, three shots, and the sound of shelling was accompanied by the cheers of Zhu Yusheng and others. By the time it got dark, they had fired more than forty shells.
"Okay, I think the quality of our artillery has passed the test. Let's go and see how the shells are firing." Song Wu asked the artillery to stop and said. Following his gaze, everyone realized that so many shells had been fired.
High-explosive bombs and armor-piercing bombs made in Germany and Yan'an have all been tested. Looking at the shells, I can't help but feel a little distressed. How many Japanese can be killed by this.
Everyone came to the opposite side of the test firing range and saw the steel plates that had been put away one by one. Comparing the bullet holes on them, Song Wu shook his head and said, "There is still a gap. Our penetration depth is seven or eight millimeters shallower than the German artillery shells."
, but when we use German artillery shells, there is not much difference with the original artillery."
Zhu Yusheng analyzed, "I think it's the warhead. I think we can write a report."
——Yan'an
Wang Fei is Mr. Peng's personal bodyguard. He came to Yan'an this time to bring some information about Shanxi to the central government. After a long journey, he also got three days of rest. He came to the streets of Yan'an, ready to buy something to take back.
After all, Yan'an at this time was rich in materials due to large-scale production and a stable environment, and there were many things. There were also some daily necessities brought by Jiang Cheng from later generations to enrich the market.
Suddenly, a figure walked by and a small red bag fell in front of him. Wang Fei hurriedly knelt down and picked it up. He only felt a faint fragrance. He quickly looked around to return it to the owner, but he couldn't find anyone.
Wang Fei hesitated for a while and shouted loudly, "Which comrade dropped the bag? It's a red bag! Everyone, check it out. I found a red bag."
Everyone touched their pockets without any worries, and suddenly a female voice said, "I'm sorry...that Eighth Route Army comrade, this bag is mine."
Wang Fei looked back and saw the face of a 26- or 7-year-old woman. She was wearing shabby but clean clothes and had a beautiful face. She was none other than Yoshiko Kawashima.
"Tell me what's inside? I'll take a look and return it to you if it's right." Wang Fei secretly took a look inside the bag and said.
"There are more than three yuan, as well as my card and my ID. My name is Jin Yuhui." Kawashima Yoshiko lowered her head and said shyly.
Wang Fei looked at the blushing Yoshiko Kawashima and couldn't help but feel a little moved. He quickly lowered his head and turned around to hand the bag to Yoshiko Kawashima and said, "Yes, here you go, be careful."
Yoshiko Kawashima said gratefully, "Thank you so much. I don't know what to do if I lose it. Can I treat you to dinner?"
Wang Fei quickly shook his head and said, "Our Eighth Route Army has discipline and cannot eat from you people."
Yoshiko Kawashima secretly resented it and said, "That can't be done like this. I look a little younger than you. I'll accept you as my eldest brother. My sister invites my brother to dinner. You have nothing to say, right?"
He took Wang Fei's hand and walked towards the restaurant.
Wang Fei was born as a tenant farmer. He was chosen by Mr. Peng to be his personal bodyguard because of his honest duty. He didn’t have much experience in dealing with women. Faced with Kawashima Yoshiko’s enthusiasm, he was anxious, shy and anxious, so he wanted to get rid of Kawashima.
Yoshiko's hand seemed to be weak, and she couldn't shake it off.
"What, Brother Wang, do you think I'm ugly and not worthy of being your sister?" Yoshiko Kawashima said, her eyes turned red, and Wang Jiji hurriedly said, "No, no, I...I don't know what to say.
, I really can’t let you treat me to a meal, so okay, I’ll treat you to a meal, okay? Oh, don’t cry, I...I was wrong, I apologize to you." After that, he saluted him.
Yoshiko Kawashima laughed through tears, pointed at Wang Fei and said with a smile, "You are like a fool, why don't you invite me to dinner?"
....
Wang Fei shyly looked at Yoshiko Kawashima who was receiving the award on the stage. After meeting Yoshiko Kawashima for a meal, the two said goodbye to each other. In this war era, Wang Fei didn't know if he was still thinking about this wave.
There was still a little regret when we could meet each other, but in the next two days, he kept meeting Yoshiko Kawashima, by the Yan River, on the road, and in the market. If there hadn't been a chirping little girl named Yunyun beside him all the time,
Jin Yuhui was talking, and once Jin Yuhui even walked over without seeing him. He had to think that Jin Yuhui did it on purpose. But now he couldn't help but think that God was hinting something, and he was already 27
, and it is suitable for Kawashima Yoshiko, who looks only 26 or 7 years old. Of course, he also remembers that he is an Eighth Route Army soldier, and the regulations of the 258th Regiment are firmly in his mind. He is already over 25 years old.
He has also been a soldier for 8 years, but his level is not high enough. He is already thinking about whether he can ask Boss Peng for instructions to join the army when he returns this time, make more military exploits, and then be promoted to regimental commander so that he can get married.
As he clapped his hands, he imagined how he would get married. The appearance of the girl next to him became more and more clear. If it wasn't Yoshiko Kawashima, who was it?
——Taiyuan
Two days have passed, and the artillery at Yanmen Pass shows no sign of stopping. The Japanese army seems to have endless artillery shells. The entire Yanmen Pass position has been blown to pieces. If it weren't for the large number of bunkers and tunnels built by the Eighth Route Army at that time, the Shanxi-Sui Army would be attacked again and again.
If the Japanese charge is defeated, Yanmen Pass may have been lost long ago.
"Sir Yan, Chairman Chiang asked us to hold on for another half month. Wei Lihuang's troops have begun to dispatch. They are Liu Maoen's troops of the 14th Group Army. They have now left Zhongtiao Mountain." Yang Aiyuan said to Yan Xishan excitedly.
Yan Xishan nodded with satisfaction and said, "Yes, there is Xinkou behind Yanmen Pass. If you persist for half a month, it won't be a big problem."
"Report, urgent military situation." A communications soldier saluted and said to Yan Xishan.
Yan Xishan took it and took a look. The pupils in his eyes suddenly dilated. He walked quickly to the map and looked at it. His brows suddenly turned into eight characters. He stamped his feet and shouted, "Ah! I fell into the little devil's trick again. Didn't the devil want to do it?"
If they go to Xinkou, they are going to Jingle!"
Yang Aiyuan quickly asked, "Sir Yan, what happened?"
Yan Xishan handed the telegram to Yang Aiyuan and said, "The Eighth Route Army's telegram said that their planes had discovered a large number of Japanese troops between Ningwu and Jingle and were marching south."
Yang Aiyuan said in disbelief, "It's impossible. Ningwu's defenders have been sending normal telegrams these days! Come on, someone, send telegrams to Ningwu!"
After a while, another telegram that no enemies appeared came to the hands of Yan Xishan and others.
Yan Xishan shook his head and said, "The Eighth Route Army will never make this joke. I believe Ningwu has really been lost."
Yang Aiyuan shook the telegram and asked, "Then how should we explain this?"
Yan Xishan smiled bitterly and said, "How else can you explain it? Ningwu's telegraph and transmitter should have been seized by the Japanese army. They were sent to us by the Japanese! When you generate electricity, just say, Ningwu little devil, I know it is you.
Just wait, I will twist the emperor's head off and use it to kick a ball."
Yang Aiyuan wiped the cold sweat from his head and nodded. After a while, the telegram received a response... "Bagh Ya Road!"
Yan Xishan closed his eyes, sat down slowly and said, "How many people have we arranged on this road?"
Yang Aiyuan lowered his head and said, "There is only one army."
At this time, Yan Xishan had eleven armies under his command, but the total strength was only a little over one hundred thousand, and each army had less than ten thousand men.
Yan Xishan shook his head and said, "Tell them the situation immediately, let them prepare to fight, and mobilize troops to go to Gujiao. Other places are too far away, and we can't take care of them..."
After saying that, Yan Xishan asked again, "Where is the Eighth Route Army? Aren't they still sending troops?"
Yang Aiyuan shook his head and said, "The Eighth Route Army replied that they have been dispatched. It is just a military secret and cannot tell us the specific situation. Our people also found signs that they did have a gathering of troops. But we cannot detect the specific situation."
Yan Xishan sighed and couldn't help but feel like he was in a glass bottle. Others could see what he was doing, but he had no idea what others were doing. Was he really old?
On the other side, Jiang Cheng came to Yan'an again.
Jiang Cheng looked at the report handed to him by Chairman Mao and nodded and said, "Not bad. The production of our anti-tank guns has begun. There is just a gap between the armor-piercing bullets and those of the original German factory. The main reason is the quality of the steel. But our anti-tank guns
The steel plant has not even met our requirements in terms of quantity, let alone quality, and we still have a long way to go."
Chairman Mao nodded and said, "I asked Ren Chi to prepare a document on Shanxi's industrial development, and I would like to trouble you to make a few more trips."
Jiang Cheng smiled and said, "Chairman, don't worry, I promise to complete the task. This time we conquer Shanxi, the overseas Chinese are all cheering, and their support for us is even greater."
Chairman Mao shook his head and said, "The fight is not over yet. Mr. Zhu and Mr. Peng are still commanding from the front. We have to fight another war. Our air force has been under great pressure recently. Do you think it can be done again?"
Add more planes.”
Jiang Cheng immediately said, "Okay, I'll start taking action immediately when I get back this time."
Jiang Cheng returned to his residence and went for a walk with Yu Yishan by the Yanhe River. Li Qian followed behind Jiang Cheng. There were still so many people in Yanhe. From time to time, central leaders waved to Jiang Cheng. Due to the large number of people, there were many eyes.
, and didn’t say anything. This kind of behavior is very common in Yanhe. After all, most of the people here are red party members and students. Everyone who meets them without looking up, many of them are acquaintances.
Not far away from Jiang Cheng, Wang Fei and Kawashima Yoshiko were also walking. Wang Fei was stupid and only listened to Kawashima Yoshiko chatting about strange things. Every time an acquaintance laughed and teased Wang Fei, Kawashima Yoshiko would
Standing up to speak for Wang Fei made Wang Fei feel more and more fond of Kawashima Yoshiko, and the look in his eyes became softer and softer.
