Zheng Jiakang carefully buried a one-pound landmine that had just been successfully trial-produced into the soil, laid out the leads, and then placed three wooden puppets around the mine. These three wooden puppets were used to test the lethality of the mine. Arrangements
When it was ready, Zheng Jiakang withdrew to 50 meters away with the technicians from the arsenal.
"Get ready, all departments pay attention." Zheng Jiakang warned loudly, but he was inevitably a little nervous.
It has to be said that the batch of inferior land mines produced last time gave Zheng Jiakang a great stimulus. After receiving feedback from Xiao Yanyue, Zheng Jiakang personally led a team to form a technical team to analyze the previous land mines.
, it was found that the main reason for the low lethality was that the cast iron shell was too thick!
Because the cast iron shell was too thick, the mine only split in half after the explosion.
Therefore, Zheng Jiakang specially improved the process this time, not only reducing the wall thickness of the cast iron shell, but also imitating the Japanese melon grenade, casting the shell into small squares, and the grooves between each two small squares were more
Thin, it is easier to break, which will produce a large number of fragments!
Don't underestimate such a small technical improvement.
In order to make the shell thinner and cast grooves, Zheng Jiakang and a dozen of his apprentices worked hard for more than ten days and solved more than a dozen process problems. Today, the casting was finally successful.
Then, Zheng Jiakang couldn't wait to go to the test explosion field to test the power.
"Attention all departments, there is a ten-second countdown, ten, nine, eight...one!" When the ten-second countdown was over, Zheng Jiakang pulled the fuse hard, and the landmine fifty meters away exploded with a loud bang, and the place immediately vacated.
A dazzling red light erupted, and the two wooden dolls placed within two meters of the explosion point were instantly overturned to the ground.
Before the smoke cleared, Zheng Jiakang was the first to rush forward.
Rushing into the explosion site, Zheng Jiakang's eyes first fell on the wooden doll placed directly on the landmine, only to find that the two wooden legs of the wooden doll had been completely blown to pieces, and the wooden body was also covered with cast iron fragments.
, Zheng Jiakang roughly counted, there were at least twenty pieces of fragments! And they were nailed extremely deep!
If this were on a real battlefield, this "japan" would definitely die as hard as he could.
Look at the puppet two meters away. Although it remains intact, it has been overturned to the ground, and its body is also covered with fragments, and at least three fragments hit vital parts. If this were a real battlefield, this "
"The little devil" is almost impossible to save.
Look at the doll ten meters away. It is still standing, but it has a lot of fragments nailed into it. Judging from the depth of the fragments, it is not enough to cause fatal damage, but there is absolutely no doubt that it has lost the ability to move.
, that is to say, after improvement, the killing radius of a pound of explosive mine is about ten meters.
"Master, the lethality should be about the same, right?" a student said happily.
As the director and chief engineer of the arsenal, Zheng Jiakang led more than a dozen students.
Zheng Jiakang nodded and said with some emotion: "So, empiricism kills people. In the past, at Hanyang Arsenal, all grenades and landmines were made of yellow explosives. After arriving at Dameishan Arsenal, I directly used yellow explosives.
The specifications were copied, and the result was that one exploded and two exploded. You must learn this painful lesson."
"Yeah." More than a dozen students nodded repeatedly, with humility on their faces.
At this time, an engine roar suddenly came from outside the test explosion site. When Zheng Jiakang and a dozen students turned around to look, they saw a three-wheeled motorcycle speeding over like lightning. It did not slow down after breaking into the test explosion site.
, unexpectedly rushed straight towards Zheng Jiakang and the others, and in the blink of an eye, they were already less than ten meters apart.
Zheng Jiakang had already seen clearly who was coming and stood still, but the dozen or so students under him all turned pale with fright and ran away, but then the three-wheeled motorcycle came.
A beautiful flick, and then stopped in front of Zheng Jiakang with a crunch, and in the end the distance was only half a meter.
"Old Zheng." Xu Rui's Zheng Jiakang winked and said, "Someone came to me to sue you."
"It's Minister Xiao, right?" Zheng Jiakang guessed it right away and said with a wry smile, "I really don't blame her for complaining about this. I made an empiricist error and copied the specifications of grenades and mines from the Hanyang Arsenal.
As a result, there was a problem, because the yellow explosive used in Hanyang Arsenal was black powder used here."
Xu Rui said: "I was thinking about this on the way here. Hasn't Professor Zheng Erqiang from the research institute already developed yellow explosives? Why does your arsenal still use black powder when producing grenades and landmines?"
"Commander, I was just about to tell you this." Zheng Jiakang said with a wry smile, "Professor Zheng and the others have indeed developed yellow explosives and have prepared the process for producing yellow explosives. But the problem is,
Without a chemical plant, no matter how good the process is, it will be useless and yellow explosives cannot be produced."
"Chemical plant?" Xu Rui's brows furrowed.
Speaking of this chemical plant, it has indeed become a thorn in Xu Rui's side.
At present, the power plant, cement factory, and arsenal in the Dameishan base are all in operation. Even the steel plant has built two small blast furnaces. The first pot of molten iron was smelted not long ago. Although the quality of the iron needs to be improved, it can only be used
To produce cast iron casings for grenades and mines, but at least it can already produce steel.
But this chemical plant cannot be solved by local methods.
Because there are so many professional equipment involved in chemical plants, let alone pumps and valves. As long as you are willing to spend money, you can get them in Japanese-occupied areas and even Kuomintang-controlled areas, but things like centrifuges, dust collectors, filter presses, and dryers
, ball mills, mixers, gasifiers, radiators, compressors, reactors and other professional equipment cannot be bought even if you have money.
Why can't you buy it? Because there is no such thing in China!
Speaking of this, we have to start with Chairman Chiang. To put it bluntly, Chairman Chiang is a big comprador. He represents the interests of the comprador class. What is a comprador? A comprador is a middleman who serves foreign capitalists in the Chinese market.
Or managers make money by reselling foreign goods in the Chinese market.
With a comprador-dominated country, you can imagine that heavy chemical industries with extremely high technology and high profits such as chemical plants would be completely impossible to appear on Chinese soil. The so-called golden decade and the so-called rapid development of China's economy were actually really
What is developed is nothing more than the foreign trade economy, light industries such as textiles, or mining.
As for heavy industries such as steel, metallurgy, chemicals, materials, machinery, etc., China either does not have them, and even if it does, the scale is very small. For example, when the National Government's production capacity was at its peak, the annual steel production was only more than a thousand.
tons, less than a fraction of Japan’s, which is really pitiful to say the least.
Zheng Jiakang continued: "Commander, the steel plant cannot produce high-quality alloy steel at the moment, but even if it only relies on the rails sent by militias from various places, it is barely enough. At least twenty Maxim heavy machine guns can be produced every month.
Production capacity can be guaranteed, but without a chemical plant, I really can’t produce a single bullet.”
"Okay, I already know about this, I will find a way." After Xu Rui finished speaking, he turned around and left.
Xu Rui has always been vigorous and resolute in his work. Since he has already found out that the crux of the problem lies in the chemical plant, there is no need to stay in the arsenal anymore. So Xu Rui hurriedly drove to the Institute of Chemistry not far away and found Professor Zheng Erqiang, but
There is no use asking Professor Zheng Erqiang about this, because there is really no way to replace chemical equipment with earth-based equipment.
The final result of the discussion was that there were only two ways to go. One was to move the Hanyang Arsenal to Chongqing and the small chemical factory to Dameishan, and the other was to import a complete set of equipment from abroad. The first way was obviously impossible, so the only option was to
There is only one way to import a complete set of chemical equipment from abroad.
Xu Rui immediately drove back to Meizhen and found Cherev and Stilwell in the classroom of the youth training team.
Nowadays, the conditions of the Dameishan Military Division have been greatly improved. All units have built barracks. The Youth Training Team, as a reserve officer training camp, is no exception. Xu Rui even has a dedicated office in the Youth Training Team. Now Xu Rui will cut
Lev and Stilwell invited him to his private office and asked Xu Ye to serve melon tea.
Xu Rui smiled and said: "This is an authentic Lu'an melon slice. Can you two try it?"
Stilwell was an upright person and after hearing this, he immediately picked up the cup of tea and tasted it, but Cherev was from the KGB and felt very wary.
So Cherev did not pick up the tea cup, but asked with a smile: "Does Commander Xu have something to talk to us about?"
Stilwell was stunned when he heard this, and quickly put the tea cup back on the table. I dare not drink this tea casually. Chinese people are really complicated in their behavior and not happy at all.
"Okay, let me tell you the truth then." Xu Rui said herrily, "Mr. Cherev, General Stilwell, I want to import a complete set of chemical equipment needed to start a small chemical plant. I know that the United States and
The Soviet Union is undergoing a chemical revolution, and petrochemical industry is completely replacing coal chemical industry, so there will definitely be many coal chemical plants that need to be eliminated."
After a pause, Xu Rui continued: "For your country, these coal chemical equipment are production capacities that need to be eliminated, but for us in China, they are urgently needed high-end equipment. We are willing to pay high prices to import them from your country. I don't know.
Are you two willing to pull strings and do us a favor?"
Cherev waved his hand and said: "Commander Xu, we in the Soviet Union may not be able to help you with this, because our Soviet Union has just completed the second five-year plan, and now the third five-year plan has just begun. In various industrial fields,
In particular, the heavy chemical industry is undergoing rapid expansion, so there is really nothing we can do to help.”
