#219 - Li Yunlong's Arrival
In terms of the steel industry, from indigenous blast furnaces to open-hearth furnaces, and the latest electric furnaces, the border region has become very mature. It possesses a large number of professionals who can guide construction and production. The only thing that Ren Zhong needs to personally handle is sending samples of local ore and various auxiliary materials to the border region so that Ren Zhong can provide a suitable production process formula based on the local material conditions.
Others cannot do these things on his behalf. Only Ren Zhong can bring them back to the main world, have Professor Hu measure and adjust them, and then bring back the formula.
This ensures the quality of steel produced in each region is guaranteed.
Ren Zhong doesn't need to invest too much energy in this aspect to solve it.
Now, high-strength aluminum alloys are used in too many applications.
Not only in aviation but also in civil applications, they are even more widespread.
The 10X0 series of ordinary aluminum alloys can be used for extruded coils for the food, chemical, and brewing industries, spun concave utensils, welded parts, heat exchangers, and as a substitute for copper as wires, conductive stranded wires, busbars, and transformer strips in the power industry. These are all places where Ren Zhong urgently needs to expand factories and power systems. If supply is opened up, even a thousand tons a month may not be enough.
The 2XXX series of high-strength aluminum alloys have more high-end uses. They are mainly used in aviation, such as heavy aircraft, forgings, thick plates and extruded materials, wheels and structural components, first-stage fuel tanks for multi-stage rockets and spacecraft parts, aircraft skins and structural parts, bulkheads, wing ribs, wing spars, rivets, etc., as well as truck frames and suspension systems, engine parts, etc.
If aircraft and rockets achieve large-scale mass production, one fighter jet will require several tons, and rockets will also require a lot. Mass production of 20 fighter jets will require almost 50 tons or more. If you add rockets, another hundred tons will be gone.
These are mainly current military industrial demands. When large-scale industrialization is rolled out, the demand will be far from being met by a few thousand tons. According to the demand in the main world, the current monthly aluminum production is 6 million tons!
However, the energy consumption of this product is also the highest in Ren Zhong's hands, second only to making peace bombs. Production has not yet been fully opened up, so for the time being, we will first meet the rigid demand in the aviation field, mainly preparing for the upcoming large-scale mass production of P51D Mustang fighters, while taking into account the needs of factory pipelines, special utensils, and the power industry.
The electrolytic aluminum plant built on the edge of Zhongtiao Mountain has an initial design production capacity of 500 tons per month, and a 6MW thermal power plant has been built to support it.
If it were just pure electrolytic aluminum, Ren Zhong wouldn't need to personally train them, but to produce different aluminum alloy products, no one in this world knows the formula better than Ren Zhong.
The production of aviation aluminum is completely different from that of ordinary aluminum. Take 2A12 aluminum alloy as an example, it requires a variety of materials such as silicon (≤ 0.50), copper (3.8 ～ 4.9), magnesium (1.2 ～ 1.8), zinc (≤ 0.30), manganese (0.30 ～ 0.9), titanium (≤ 0.15), nickel (≤ 0.10), and iron (0.000 ～ 0.500) to be made with special processes. The process formula is a range in books, and specific data must be found from Professor Hu to configure.
No one can do these tasks except Ren Zhong. Moreover, only Ren Zhong can confirm what kind of aluminum alloy is needed. Others have not yet established knowledge and awareness in this area.
In this time and space, these are top-secret alloy formulas, and at the same time, the production process must also be a specially treated secret process.
Even in the border region, confidentiality education must be carried out, and confidentiality regulations must be formulated and implemented with advanced confidentiality conditions before entering such a workshop to see these formula requirements and produce such aluminum alloy crystals according to the specific process flow.
Ren Zhong must open up the entire set of things and teach the management personnel here. If these things are waited for to be explored and summarized on-site, it will take forever. Now we can't wait that long, and everything will be implemented according to Ren Zhong's requirements.
For these special aluminum alloys, not only is the production special, but also the processing is also very complex with heat treatment specifications, including homogenization annealing, complete annealing, rapid annealing, quenching, and aging, etc. One by one, problems need to be solved. If Ren Zhong hadn't moved the relevant information from the main world for on-site teaching, no one here could explain these things clearly.
They don't know what to do with these materials.
This set of things, like the artillery steel production in the steel plant, is the top special material production line in the border region and base area.
This entire set of supporting infrastructure made Ren Zhong really busy for a while.
"Old Brother Ren, I've missed you to death, Old Li has! It's been so long since we last met, truly a damn difficult thing. Do you still have that 'special brew' of yours today? I feel like that stuff has some kick, not inferior to sweet potato liquor."
That day, after Ren Zhong finished work, he didn't expect Li Yunlong to suddenly come knocking, shouting at him.
"Old Li, why aren't you in Heyuan? What are you doing running all the way here?" Li Yunlong's Independent Regiment's base was in Heyuan and Anping, which wasn't exactly close to Zhongtiao Mountain in Ze Prefecture.
Ren Zhong hadn't expected this guy to run so far just to see him.
"Isn't it because I missed you, Brother? I rode my horse like a madman for hundreds of miles to get here. We absolutely have to have a good drink!" Li Yunlong said with a grin.
However, looking at his expression, Ren Zhong knew that this guy wasn't telling the truth; something was definitely up.
"Alright, Old Li, it's been a while since we had a good drink together. You, Old Brother, are doing so well in Taiyue, living the life of a division commander. I haven't even had a chance to congratulate you yet," Ren Zhong said with a smile.
"Tonight, we'll just have a small drink."
"Old Brother Ren, you know, these days we're just doing construction, construction, and more construction. They won't even let the main forces go out and fight the Japanese devils anymore. Our Independent Regiment is almost turning into a pure construction team. Although life is fulfilling, I, Old Li, feel a bit uneasy. If we continue like this, and the Japanese devils haven't been driven away, what if they come back? Wouldn't all the things we've built be for nothing?"
At this stage, the Japanese devils didn't have any major movements. Ren Zhong estimated that the Japanese devils were brewing something big. After all, the sweeps from the original timeline weren't quite enough for the base areas now.
Two or three divisions of troops daring to enter several major base areas would probably have to lose a layer of skin before they could get out of the mountains.
Under normal circumstances, after seeing the miserable state of the 36th Division, the Japanese devils wouldn't use division-level scale sweeps again. They would have to organize a campaign on the scale of the Battle of Zhongtiao Mountain to enter the mountains and seek a decisive battle.
Therefore, before preparing for a large-scale campaign, the Japanese devils were very well-behaved, basically not making any major moves to sweep, not even coming out to cause trouble during the summer harvest, allowing the base areas to have a peaceful summer harvest season.
On the other side, the border region and base areas were also busy with their own construction, digesting the newly occupied base areas, and at the same time sending out armed work teams to more distant enemy-held areas, extensively developing their own sphere of influence in a larger space.
However, the main forces stopped to rest and further train, not launching attacks against Japanese devil strongholds above the county level. The North China region generally showed an eerie calm.
Except for the guerrillas in the occupied areas who were constantly attacking Japanese devil blockhouses and strongholds, carrying out large-scale guerrilla warfare behind enemy lines, battles above the main regiment level were basically called to a halt by the headquarters.
The most \\u22a5 new \\u22a5 small \\u22a5 said \\u22a5 at \\u22a5 six \\u22a5 9 \\u22a5 \\u22a5 book \\u22a5 \\u22a5 bar \\u22a5 \\u22a5 first \\u22a5 release!
The entire North China battlefield, the GMD naturally got used to being a small, transparent entity. If you hit it, it definitely wouldn't mobilize. In this way, all three parties tacitly agreed not to launch major operations, fearing that they might accidentally break the hard-won balance.
For others, this was a rare moment of leisure.
But for someone like Li Yunlong, who couldn't stay idle, these days of being shackled were simply as uncomfortable as being in prison.
If it weren't for the heavy engineering and construction tasks waiting for Li Yunlong, this guy would probably have violated discipline long ago and gone to find trouble with the Japanese devils on his own.
Hearing that Ren Zhong had arrived in the Zhongtiao Mountain area of Ze Prefecture, Li Yunlong dropped the work in his hands, handed it over to Zhao Gang, Zhang Dabiao, Shen Quan, and the others, and brought the monk to find Ren Zhong.
On the one hand, to reminisce about the old days, and on the other hand, to try to extract something from Ren Zhong's mouth.
"Old Li, there's no need to rush this matter," Ren Zhong took out a bottle of special brew from the main world, with the packaging removed, opened it, and poured out two bowls. Instantly, the room was filled with fragrance, making Old Li drool, and he immediately took a big gulp.
Although this guy kept muttering about sweet potato liquor, feeling that even the best liquor in the world was comparable to his sweet potato liquor, in reality, after drinking Ren Zhong's special brew, Old Li couldn't even drink sweet potato liquor anymore, and his alcohol tolerance had decreased a lot.
"Look, the construction we're doing now, isn't every single one bigger than our Yangcun and Heyuan, with more factories?"
Ren Zhong said unhurriedly.
"This time, in addition to producing weapons, we will also produce a large number of cars, so that the troops can quickly transfer thousands of miles in the future. This is sharpening the knife does not delay the woodcutter's work. And I also want to tell you that this time it is not only producing cars, we will also produce tanks!"
"What? Tanks!" Li Yunlong's eyes immediately widened like copper bells when he heard Ren Zhong say this.
Currently, the construction work of several tank sub-factories is in full swing, but apart from the highest level of the base area, few people know what these factories will specifically produce.
Even Li Yunlong hadn't received any information in this regard. For him, the arrangement from above was to build the factory well, prepare to receive a batch of mechanical equipment, and at the same time require the Heyuan and Yangcun machine tool factories to start mass-producing new equipment according to the requirements of the border region.
For Li Yunlong, this kind of pure construction work was very boring.
Now, hearing that the factory he was building was actually going to produce tanks, he immediately became energetic. Without saying anything, his saliva was about to flow out.
