Traveling through the sword to engage in military industry.

Chapter 219 Li Yunlong's Arrival
In the steel industry, from traditional blast furnaces to open-hearth furnaces and the latest electric furnaces, the border areas are already very mature and have a large number of professional talents to guide construction and production. The only thing that Ren Zhong needs to intervene is to send local ore and various auxiliary material samples to the border areas so that Ren Zhong can provide a suitable production process formula based on the local material conditions.

No one else can do these things for them. Only Ren Zhong can bring them back to the main world, measure and adjust them with Professor Hu, and then bring back the formula.

Ensure that the quality of steel produced in each region is guaranteed.

This is a heavy task that can be solved without investing too much energy.

However, for the construction of the electrolytic aluminum plant, Ren Zhong had to go to the Zhongtiao Mountain area in person to cooperate with the local construction and begin to provide a full set of technical guidance for the equipment and production processes of the electrolytic aluminum plant.

It should be noted that due to limited resources, although the electrolytic aluminum plant in Ikh Ju League has opened up all the production process flows, its production capacity has not been increased. According to the current stable monthly production capacity of less than 100 tons, this output is obviously not in line with the large-scale demand for aluminum.

According to Ren Zhong's plan, the production of aluminum alloys must reach a scale of more than 3 tons within half a year, or at least 500 tons per month, in order to keep up with the development pace of the expanded military industry and other new factories.

Nowadays, high-strength aluminum alloys are widely used.

Not just in aviation, but also more extensively in civilian use.

The 10X0 series of ordinary aluminum alloys can be used in extruded coils for food, chemical and brewing industries, spun concave vessels, welded parts, heat exchangers, and replace copper as wires, conductive strands, busbars, transformer strips, etc. in the power industry. These are all very urgently needed for factories and power systems that are tasked with expanding their business. If the supply is open, thousands of tons a month may not be enough.

The 2XXX type of high-strength aluminum alloy series has a relatively high-end use. It is mainly used in aviation, aircraft heavy, forgings, thick plates and extruded materials, wheels and structural elements, multi-stage rocket first-stage fuel tanks and spacecraft parts, aircraft skins and structural parts, bulkheads, wing ribs, wing beams, rivets, etc., as well as truck frames and suspension systems, engine parts, etc.

If airplanes and rockets are mass-produced, a fighter jet will require several tons, and rockets will also be in great demand. Mass production of 20 fighter jets will require more than 50 tons. If the rockets are added in hundreds of tons, the space will be stretched.

These are mainly the current military needs. When industrialization is rolled out on a large scale, the demand will be far more than a few thousand tons can satisfy. According to the demand of the main world, the current monthly aluminum production is 600 million tons!

However, the energy consumption of this product is so high that it is second only to the production of peacetime bombs in Ren Zhong's hands. Production has not yet been opened, so it is temporarily used to meet the rigid demand in the aviation field and prepare for the upcoming mass production of the P51D Mustang fighter, while taking into account the needs of factory pipelines, special equipment and the power industry.

The electrolytic aluminum plant built on the edge of Zhongtiao Mountain has an initial design capacity of 500 tons per month, and a 6MW thermal power plant was built to support it.

If it is just electrolytic aluminum, there is no need for Ren Zhong to personally teach it, but if different aluminum alloy products are to be produced, no one in the world knows the formula better than Ren Zhong.

航空铝材的生产比起普通铝材来说完全是两回事。就2A12铝合金这种，需要硅（≤0.50）、铜（3.8～4.9）、镁（1.2～1.8）、锌（≤0.30）、锰（0.30～0.9）、钛（≤0.15）、镍（≤0.10）和铁（0.000～0.500）多种材料在特殊工艺制作才行，工艺配方方面书本都是一个范围，具体数据必须得找到胡教授那边去配置。

No one else can do these tasks except Ren Zhong. And only Ren Zhong can confirm what kind of aluminum alloy is needed, as no one else has the knowledge in this area.

In this time and space, these are top-level confidential alloy formulas, and the production process also requires special confidentiality processing.

Even in the border areas, confidentiality education must be carried out, confidentiality regulations must be formulated, and high-level confidentiality conditions must be implemented before one can enter such a workshop, see the formula requirements, and produce such aluminum alloy crystals according to the specific process flow.

Ren Zhong had to get all the things connected. If the management personnel on the church side were to wait for the site to explore and summarize these things themselves, it would take a long time. Now they couldn't wait that long, so everything had to be carried out according to Ren Zhong's requirements.

For these special aluminum alloys, not only are the production aspects special, but the processing aspects also have very complex heat treatment specifications, including homogenization annealing, full annealing, rapid annealing, quenching and aging. These issues need to be solved one by one. If Ren Zhong hadn't moved the relevant materials from the main world for on-site teaching, no one here would be able to explain these things clearly.

They didn't know what to do with the materials.

This set of equipment, like the artillery steel produced at the steel plant, is a top-level special material production line for border areas and bases.

Such a complete set of supporting infrastructure kept Ren Zhong busy for quite some time.

"Brother Ren, you must have missed Lao Li so much. It's been so long since we last met. It's really not easy. Do you have any more of that special drink today? I think it's quite exciting, not worse than sweet potato stew."

After Ren Zhong finished work that day, he didn't expect that Li Yunlong suddenly came to his door and yelled at him.

"It's Old Li. Why aren't you in Heyuan? Why are you here?" Li Yunlong's independent regiment's base is in Heyuan and Anping, which is not close to Zezhou in Zhongtiao Mountain.

Ren Zhong didn't expect that this kid would run so far to see him.

"I just miss you, brother. I rode my horse for hundreds of miles here. Let's have a drink together." Li Yunlong said with his hand on his face.

However, Ren Zhong knew from his expression that this guy was not telling the truth and that something must be wrong. "Okay, Lao Li, we haven't had a good drink for a long time. Your brother is doing well in Taiyue and has become a master, but I haven't had time to congratulate you yet." Ren Zhong said with a smile.

"Let's have a drink tonight."

"Brother Ren, you said that we are now engaged in construction all day long. We are not allowed to send out the main force to fight the Japanese. Our independent regiment is almost becoming a mere engineering team. Although our life is very fulfilling, I am a little uneasy. If we continue like this, and the Japanese are not driven away, they will come back. Wouldn't all our construction work be wasted?"

At this stage, the Japanese haven't made any big moves. Ren Zhong estimated that they are holding back their big move. After all, the sweep in the original time and space is not enough for the base now.

If two or three divisions dare to enter several major bases, they will probably have to suffer a lot before they can get out of the mountains.

Under normal circumstances, after seeing the dismal performance of the 36th Division, the Japanese would not use a division-level scale to carry out a mopping-up operation. They would have to organize a campaign on a scale similar to that of the Battle of Zhongtiao Mountain before entering the mountains to seek a decisive battle.

Therefore, before making preparations for a large-scale battle, the Japanese were very honest and basically did not carry out large-scale mopping-up operations. They did not even come out to cause trouble during the summer harvest, allowing the base to have a peaceful summer harvest season.

On the other hand, the border areas and base areas were also busy with their own construction and digesting the new base areas they had just occupied. At the same time, they sent the armed work teams farther behind enemy lines to expand their sphere of influence in a larger space.

However, the main force stopped to rest and conduct further training. No attacks were launched against the Japanese strongholds at the county level or above. Overall, there was an eerie calm in North China.

Except for the guerrillas in the occupied areas who never stopped attacking the Japanese artillery towers and strongholds and launching large-scale guerrilla warfare behind enemy lines, the battles above the main regiment level were basically stopped by the headquarters.

Throughout the entire North China battlefield, Guosu is naturally used to being a small and transparent person. If you attack it, it will definitely not move out. In this way, the three parties have a tacit understanding not to launch any major actions, for fear of accidentally breaking the rare balance.

For others, this is a rare leisure time.

But for someone like Li Yunlong who can't sit still, the days of having his hands and feet locked up are as uncomfortable as being in prison.

If there were not heavy engineering construction tasks waiting for Li Yunlong, I am afraid that he would have violated discipline and caused trouble for the Japanese long ago.

Hearing that Ren Zhong had arrived in the Zhongtiao Mountain area of ​​Zezhou, Li Yunlong dropped the work in his hands and handed it over to Zhao Gang, Zhang Dabiao, Shen Quan and others, and went to find Ren Zhong with the monk.

On the one hand, they were reminiscing about the past, and on the other hand, they wanted to get something out of Ren Zhong.

"Old Li, you don't have to rush about this," Ren Zhong took out a bottle of Main World Special Li without its packaging, opened it and poured out two bowls of it. Suddenly the room was filled with fragrance, which made Old Li greedy, so he took a big gulp right away.

Although this guy kept talking about sweet potato liquor, giving people the impression that no matter how good the wine in the world was, it was only as good as his sweet potato liquor. In fact, after drinking Ren Zhong's special liquor, Lao Li could not drink sweet potato liquor anymore, and his alcohol consumption decreased a lot.

"Look, which of the construction projects we are currently building is not bigger than our Yangcun and Heyuan, with more factories?"

Ren Zhong said slowly.

"In addition to producing weapons, we are also going to produce a large number of cars so that the troops can ride in cars and quickly travel thousands of miles. This is like sharpening the knife before chopping wood. And I have to tell you that this time we are not just producing cars, we are also going to produce tanks!"

"What? Tanks!" When Li Yunlong heard Ren Zhong say this, his eyes immediately opened as wide as copper bells.

Now the construction of several tank factories is in full swing, but except for the top leaders of the base, few people know what these factories will produce specifically.

Even Li Yunlong did not receive any information in this regard. For him, the arrangement from above was to build a factory and prepare to receive a batch of mechanical equipment. At the same time, the Heyuan and Yangcun machine tool factories were required to start mass production of new equipment in accordance with the requirements of the border area.

For Li Yunlong, this kind of simple construction work is boring.

Now that I heard that the factory I built was going to produce tanks, I immediately awoke to the sleepiness and said nothing more. My saliva was drooling.
