Siheyuan: Spring and Autumn

The blast furnace is started again, and pure aluminum billets are put in first, followed by alloy materials prepared in proportion. They are melted into molten aluminum at high temperature and then transferred to the converter workshop again. After impurities are removed, aluminum alloy water is produced, which is cooled to obtain aluminum alloy billets. Then, they are kept warm at 575 degrees for 6 hours, followed by rapid cooling to make the ingot alloy homogenous. At this point, a day has passed.

The next day, work continued. The aluminum alloy billets were sent to the rolling mill, heated to about 450 degrees and deformed by a rolling mill to form aluminum materials of different shapes. Of course, Qin Zheng only required two shapes, one was aluminum alloy tube and the other was aluminum alloy plate.

This smelting experience opened the eyes of Qin Zheng and his three classmates. It was the first time for them to see up close the blast furnace, converter, ingot mill, section steel rolling mill, plate and strip rolling mill, pipe rolling mill and other mechanical equipment. It can be said that this close observation of the aluminum alloy production process was very beneficial to their academic studies.

After the rolled aluminum alloy was cut, Qin Zheng only took away two aluminum alloy plates and two aluminum alloy tubes, and left the rest in the rolling mill.

The purpose of taking it away was naturally to ask the school to test the aluminum alloy, to test its physical and mechanical properties.

After returning to school, Qin Zheng and his three companions went straight to teachers Shen Junxian and Hu Zhenzhong, handed the aluminum alloy materials to them, and told them what had happened. The two were shocked.

Shen Jun first stared at the tube in his hand, then suddenly looked up and said, "I have a strong feeling that your formula will bring a huge surprise to our country."

Of course, science cannot rely on hunches or guesses; it must be tested.

Although Kyoto University does not have equipment to produce aluminum alloys, it certainly has laboratories to test material properties.

Qin Zheng knew the value of this formula, but he absolutely underestimated the importance of aluminum alloy formula in this era. When the two teachers reported the performance test data to the department, the news had reached the core in a very short time.

It can be said that the performance test results of aluminum alloy are almost the same as the test results of aluminum alloy in most parts of U.S. aircraft. This shows that this kind of aluminum alloy can be fully used in the aerospace field, and it cannot be overemphasized at this time.

On these US aircraft seized by the country, aluminum alloy accounts for 70% to 80% of the total weight and will be an indispensable part of the aerospace industry.

Soon, an order was issued from the central government, and the military went to the steel mill to retrieve the alloy formula and transport all the aluminum alloys away. All personnel involved in the production signed a confidentiality agreement.

Afterwards, Qin Zheng met the first Zhisi again. His current identity is the Vice Premier of the State Council and the Minister of National Defense. The two are acquaintances. When he was in the court, Qin Zheng was his soldier, and of course, he still is now.

"Are you disappointed to see an old man like me?"

As soon as they met, General Peng started teasing Qin Zheng.

Qin Zheng's face was slightly embarrassed with excitement. He smiled and said, "Commander, you still remember it? How could I be disappointed? I'm excited. Look, I'm so happy that I'm beaming with joy."

After saying this, he couldn't stop smiling.

"Hahaha, you passed. Come and sit down, boy, you are indeed a talent. You are not ambiguous in fighting, and I didn't expect you are also good at inventing things."

"That's right, didn't you see whose soldier I am!"

The words were not very modest, but they made General Peng laugh: "Hahaha, I love to hear that."

An hour later, the meeting ended and Qin Zheng left happily. The atmosphere of their conversation was very good and the content of the conversation was naturally kept confidential.

This incident also had a good result. Peking University signed a cooperation agreement with the steel rolling mill, which set a precedent for cooperation between the university and enterprises.

Although the reaction to this incident was a bit big, Lou Jianye was not surprised but happy because he was also received by the leadership and was praised for his free help to Qin Zheng in developing aluminum alloys.

Lou Jianye felt extremely happy, this Qin Zheng was simply his lucky star!

This aluminum alloy was officially named 7054 by Qin Zheng.

At present, China does not have its own independent aluminum alloy grade system and standards, so Qin Zheng named this 7 series aluminum alloy with zinc as the main element as 7054 aluminum alloy according to the international four-digit system and corresponding international standards.

According to the international four-digit system, if zinc is the main element, it is a 7 series aluminum alloy, and the number "0" represents the number of times the aluminum alloy has been adjusted, indicating a success. As for the last two digits, they have no practical meaning. Qin Zheng used the numbers 54, indicating that it was developed in 1954.

In fact, the aluminum alloy with this formula, known internationally as 7075, is the best aluminum alloy with very strong commercial applications.

Qin Zheng appeared at the Lou family again.

This time, Lou Jianye was even more enthusiastic. Although he was a red capitalist, he was still a businessman after all. The returns from his investment in Qin Zheng were too generous, so generous that it exceeded his imagination. Naturally, he knew what attitude he should take towards it.

The study on the second floor of the Lou family.

“Uncle Lou, last time I said I would give you a surprise, and this time I brought it.”

"Oh? The surprise you gave me wasn't enough?"

Lou Jianye laughed.

Qin Zheng would naturally not go back on his words. He smiled and said nothing more, but took out a piece of paper and placed it on the coffee table.

Lou Jianye leaned in to take a closer look. Wow, two letters of authorization, what a surprise, more than what he had asked for.

"Thank you, Qin Zheng." He thanked sincerely.

"You're welcome. Uncle Lou treats me well. I know."

After this incident, the affection between the two of them, which had a clear purpose, now became much more sincere!

Indian Krishnamurti once said: "It is interests that maintain the order of the whole world."

The existence and maintenance of every level of social relationship is utilitarian, and it is for this reason that people use each other.

Being used does not sound like a pleasant word, because there is always a feeling of being played around by others, proving one's incompetence.

If you feel that being taken advantage of is unfair and incompetent, then you might as well analyze it from another perspective. The reason why you are taken advantage of by others is not because you are stupid or incompetent. On the contrary, it means that you have enough value to be used.

Some people use you to prove that you are valuable, and some people talk about you to prove that you are capable.

In the process of exploiting and being exploited, people establish friendships with each other.

Lou Jianye felt very comfortable. Qin Zheng was really a man of character. After pondering for a while, he said, "Last time you suggested that I set up a factory in Hong Kong Island. I thought about it carefully and felt that you were right. Since the country has issued the general principles of public-private partnership, then public-private partnership is inevitable. After the partnership, my say in the factory will definitely be much smaller. However, I haven't decided what business to start in Hong Kong Island yet."

Qin Zheng smiled softly and said, "I knew that as long as Uncle Lou didn't give up his ambition, he would definitely make this choice."

Lou Jianye said, "Qin Zheng, help me with some advice and see what I can do. I can give you shares and we can become strategic partners like the factory and the school."

He saw it clearly and made up his mind to form an alliance with Qin Zheng. This would definitely be beneficial to him and would not cause any harm.

Qin Zheng smiled and said, "You have so much confidence in me?"

"That's right. Your uncle Lou was able to accumulate such a large family fortune not only because of the influence of my father, but also because of my own vision. I am confident that my vision is not bad."

Qin Zheng didn't say any more nonsense, but took out a blueprint from his bag and spread it on his large rosewood desk with a relief dragon pattern.

"This is, this is a children's bicycle? What a wonderful design, so wonderful! Ahaha, ahaha, hahahaha..."
