Chapter 1171: A wonderful journey of a piece of cannon steel (middle)

Zhu Yusen didn’t notice Tan Zhenhua’s small actions. He just continued along his own line of thinking:
If the people from the Iron and Steel Research Institute are not here today, I’ll explain them to Comrade Xiao Tan, but I’m not professional. Just listen to a simple and general meaning."
Tan Zhenhua nodded. Based on his level, this "simple and general meaning" may not be fully understood. All he cares about is the question in his mind: Where does Huaxia's electroslag remelting technology come from? Can it reach the "international advanced level" that Zhu Yusen said? If it can really reach that level, why is the quality of our gun steel lagging behind?
"Electroslag remelting technology is an important technology in iron and steel metallurgy. Except for China and Britain, which are independently developed, the source of technology in other countries in the world should be Soviet Russia, including related industries in the United States."
Zhu Yusen's first sentence completely subverted Tan Zhenhua's cognition, but he believes that with Zhu Yusen's status, status and knowledge, there must be sufficient basis for saying these.
"The discussion and application of electroslag remelting technology in our country began in 1958. It was originally a by-product of research on the basic subject of using electro-welding and alloy powder as flux. Although it is only a by-product, scientific researchers have gained Inspired, and conducted a remelting test in 1959 and got good results. The results were published in the special issue of "Welding" magazine on the tenth anniversary of the founding of the People’s Republic of China; in early 1960, the Beijing Institute of Iron and Steel built the first experimental 150 kg electroslag weight The melting furnace. In November of the same year, a 0.5-ton pilot furnace was put into operation at the Shancheng Shuangqing Special Steel Plant. In November 1961, the first National Electroslag Metallurgy Conference was held under the auspices of the Ministry of Metallurgy, which marked China The electroslag metallurgical technology of China has officially entered a large-scale research and development stage; it was not until 1965 that the Field Brown Company built the first 7-ton electroslag remelting furnace, which started seven years later than our China. At that time, Huaxia had successively built more than 20 electroslag remelting furnaces, capable of producing 54 grades of special steel, the largest of which was located in the Modu Heavy Machinery Factory, with a hundred-ton level. It can be seen that in that era, regardless of In terms of quantity or actual application level, our country is far ahead of Britain."
"What about Soviet Russia? What is the situation in Soviet Russia? Isn't it said that the electroslag remelting technology in all countries except my country and Britain originated from Soviet Russia? What about the Americans?" Tan Zhenhua couldn't bear it. Asked curiously.
"Soviet? The Americans? Haha, this is an unclear lawsuit." Zhu Yusen curled his lips and smiled: "According to the Americans, the electroslag remelting technology was invented by them, and the inventor is RKHopkins. , The time is 1935, and obtained a U.S. patent in 1939, so the technology is called the "Hopkins method" by the U.S., but the Soviets do not recognize it, and not only the Soviets do not recognize it, my country also Don’t admit it, even the British, who always wear the same pants as the Americans, don’t admit it."
"Why is this?" Tan Zhenhua suddenly turned into a curious baby.
"Because the so-called "Hopkins method" is fundamentally wrong in theory," Zhu Yusen replied: "Hopkins believes that the remelting process is "submerged arc discharge", but this is actually an electroslag process. Moreover, Hopkins himself is a family business owner. After applying for a patent, he has never authorized anyone and has been exclusively closed production. Because of fundamental theoretical errors, many key technical problems could not be resolved until the company went bankrupt. And was acquired by others."
It’s no wonder that the U.S. people treat the immature technology with a little bit of it as their own invention. This is commonplace. For example, Antonio Meucci, a great Italian under Jiuquan, is going to talk to the American Alexander Graham. Bell's collar asked: "Do you dare to say that you invented the telephone? There is a kind of thing you can say again in front of me, believe it or not, I will let you know why the flowers are so red..."
"As for Soviet Russia, according to its own description, the development situation is like this." Zhu Yusen continued to introduce: "In 1952, the famous Barton Electric Welding Research Institute also discovered some interesting phenomena while observing the welding process of arc welding and started. Continued research, and in 1958, led by Academician Meadowal, built the first 0.5-ton P909 electroslag furnace in Dnepol Special Steel Company, Uklan Zapolos, which opened the industrialization of electroslag metallurgy. Prologue."
"But it’s just as funny as it’s funny. In 1967, at the world’s first international seminar on electroslag remelting technology held in Pittsburgh, the United States, the delegates from both sides condemned the other party for theft and illegal use of the book. As for Fang’s technology, as to whether the CIA or KGB really succeeded, we outsiders have not really figured it out to this day. Of course, judging from the evidence provided by both parties, it is generally accepted by everyone now that the CIA succeeded."
"Hahahahaha", there was a burst of laughter in the conference room. It was rare to hear the story of Master Zhu, who has always been more serious, and the story was so interesting that everyone couldn't help but cheer.
Tan Zhenhua smiled and asked, "What about now? Is my country still leading in this respect?"
Zhu Yusen's expression suddenly became serious. He carefully considered the words and replied slowly: "Comrade Xiao Tan, it is difficult for me to answer your question. Is our current technical level in the field of electroslag remelting? How do you say it? It's okay to say that it is leading, and it can definitely be regarded as the number one camp in the world, but it is also okay to say that it is behind. In some respects, we are not a little bit behind."
"Uh, what's this saying?"
"I said a few things and you will understand."
"Well, please tell me, Master Zhu."
"At the Ninth International Symposium on Electroslag Remelting Technology recently held in San Diego, the United States, companies and individuals who made outstanding contributions to this new technology around the world were selected and awarded. Among them, 36 units won awards. , Huaxia accounted for three seats; among the 38 people selected for the largest contribution, Huaxia accounted for 5; the meeting also decided that the next seminar will be held in Huaxia. It can be seen that we are in electroslag remelting The contribution of the field has been respected and recognized all over the world. In addition, Modu Heavy Machinery Factory cooperated with the Beijing Iron and Steel Institute to build a 200-ton electroslag furnace in 1982, which is the world's leading, and This electroslag furnace is not what it looks like. It has provided more than 124 large forging blanks for the Qinshan Nuclear Power Station, with excellent performance and reliable quality."
"Uh, I sound like it's leading? How can I say that I'm behind?"
"The place behind is that although this electroslag furnace was designed and built by our own, the control system is a complete set of imported products from Austrian Bohler. Although the performance of this control system is not the most advanced level in the world, because the best People don’t sell it, but it’s far better than our country’s own control system."
Tan Zhenhua finally realized.
