The Grandmother in the Siheyuan

Chapter 222 Stop

Mr. Ma thought that Liu Hua wrote the article in order to write a thesis. After all, it was normal to write and publish two papers on the research of this new aluminum alloy material. However, Liu Hua did not need to be evaluated for professional title and did not want to become famous, so he did not need to write a thesis.

Liu Hua thought of something when he was smelting aluminum alloy. Forty years later, our country's aluminum production ranked first in the world, destroying the aluminum product supply chain of all other countries in the world.

Therefore, our country has only slightly adjusted the tax rebate policy for aluminum products, but it has already caused discomfort to the whole world, especially Da Piaoliang.

In the future, aluminum products can be used in aerospace, automobiles and ships, electronic semiconductors and other fields. The tax rebate policy affects the price of aluminum products, so as soon as we adjust this policy, Da Piaoliang will feel uncomfortable.

The article Liu Hua is going to write is about fully developing aluminum products and destroying the global supply chain, because no country in the world is more suitable for such development than our country.

In the article, Liu Hua talked about the scope of application of aluminum products in the future, and also talked about our country's advanced physique, which makes it more suitable for developing this industry than any other country in the world.

Because the production of aluminum requires a large amount of electricity, and our country is the only country in the world willing to invest in large-scale infrastructure. When we monopolize the global aluminum market, we will have an effective means to check and balance the West.

As for the other article, it is about vigorously developing the rare earth industry and monopolizing the entire rare earth industry. Liu Hua looks forward to the widespread application of rare earths in future high-tech. Once our country has an absolute advantage in the rare earth market, we will be able to balance the West from another aspect.

After Liu Hua submitted the article, it attracted great attention from the management. After several discussions, they even invited Liu Hua to attend the meeting.

In that conference room, Liu Hua saw many big names that he had only seen in newspapers, so he behaved a little reservedly.

"Young man, don't be nervous, just tell me what you know." The leader said with a Trumpian tone, smiling, "Your article has greatly shocked us. It seems that you have also read Guanzi."

Liu Hua shook his head: "I haven't read the Guanzi, but I know something about it. It's just like the salt and iron monopoly in ancient my country, which controlled strategic materials to curb the surrounding nomadic peoples."

Five or six leaders asked Liu Hua questions, and Liu Hua answered them fluently. The most important thing was that Liu Hua was still hiding something. There were some things he knew clearly what to do correctly, but he didn't dare to say it directly.

After two hours of questioning, the leader gave Liu Hua a cigarette and lit up himself: "Very good, this kid has given us a different inspiration. It shows that developing the economy does not mean giving up the fight against the West. On the contrary, when the economy develops well, we will strangle them. When we are big enough, we only need to move a little to suffocate them."

These words were like the final word. Liu Hua didn't know what decision the leaders had made, but in the next five years, the country's development in non-ferrous metals was obvious to all.

Another example is rare earths. The state has introduced laws to control the export of rare earths, and has to increase investment in the rare earth industry.

After answering the inquiries, Liu Hua flew to Shanghai and went to Jiangnan Shipyard to learn how to manufacture 10,000-ton hydraulic presses.

Our country's first 10,000-ton hydraulic press is 23 meters above the ground and 40 meters below the ground. The main machine weighs 2,200 tons. It has four large columns, each 18 meters long and 1 meter in diameter, and three cross beams, weighing between 100 and 300 tons. There are six working cylinders, each of which can produce 2,000 tons of pressure when working.

People standing in front of this machine seem extremely small. I am afraid that the one-piece casting technology that Lei Jun boasted about is nothing compared to this machine. "It's really a big guy." Liu Hua said in amazement: "The 10,000-ton one is so big, how big must the 50,000-ton one be?"

"Yeah, unfortunately we are facing many problems now."

The Jiangnan Shipyard was extremely welcoming to Liu Hua's coming to learn about the 10,000-ton hydraulic press. All information was open to him, and any questions Liu Hua had were answered. The pressure from above was not small, and they also hoped that more people would come to help.

After half a month of study, Liu Hua finally understood the operating principle of the hydraulic press. Time is efficiency, and he was not going to study this technology on his own, so he went directly to the system to exchange it.

Unexpectedly, I couldn’t find any information about my country’s 50,000-ton hydraulic press. If my country has not built a 50,000-ton hydraulic press, then other countries probably won’t be able to do so either.

There is actually no 50,000-ton hydraulic press technology. What kind of casting technology will our country use for large aircraft in the future? Liu Hua was very puzzled.

So he exchanged it for the C919 keel die-casting technology, which was not much, only one thousand points, but a little less because it was only for C919.

Unexpectedly, the C919 uses the 2012-ton large-scale forging press independently developed by my country. This big guy was only successfully tested in .

Considering that the industrial base in 2012 was definitely different from now, Liu Hua searched for information on large die forging presses in the system and found that Da Piaoliang had a -ton large die forging press.

So Liu Hua decided this was the one. Boeing must also use this kind of die forging press, so it would be more than enough for the Y-10.

This thing was built in 1956 by the Great Piaoliang. It is probably designed by scientists from the Hans country, so the quality should be guaranteed.

Five thousand points, even though it was only a product from 1955, it was not a small amount of money. It can be seen that during the heyday of Da Piaoliang Industry, there were indeed a lot of good products in its belly.

At a meeting, Liu Hua expressed his opinion: "It is very difficult for us to develop a 50,000-ton hydraulic press. Have you ever thought about abandoning this technology and turning to other technologies?"

“What other technology?”

Liu Hua scratched his head. "I remember that in one of the foreign technical journals that the First Ministry of Machine Building had forwarded to me, there was an introduction that Da Piaoliang built two 45,000-ton large die forging presses in 1955. At that time, Da Piaoliang's aviation industry was booming, so I think it should be enough for our university's needs now. The most important thing is that I saw this report in the 1960s, and it seemed that Da Piaoliang had not developed in this area, which means that 45,000 tons should be enough for them."

The chief engineer of Jiangnan Shipyard frowned and thought for a while: "It seems to make sense."

Liu Hua smiled and said, "Since our technology is not making any progress at the moment, why don't we stop for a while and collect some information from abroad? I think things produced in 1955 are not still kept secret, so we should be able to collect a lot of useful information. Let's cross the river by feeling our way."
