Chapter 1172: A wonderful journey of a piece of cannon steel (part 2)

It’s no wonder that in the online forums of his previous life, there were rumors that China’s "electroslag remelting" technology was imported from the West. The persuasives even made it clear that China was the technology acquired from Austria in the 1980s, and the root cause That's it.
But from Zhu Yusen’s description, it can be seen that, in fact, in the field of "electroslag remelting", Huaxia is not only the original discoverer of the technology, but also has been developing this technology independently, and has been doing both basic research and practical application for a long time. Maintain a leading position in the global industry.
However, modern science, especially modern engineering, has never been able to develop independently only by the study of one discipline. The application and progress of any new technology cannot be separated from the collaboration of multiple basic disciplines.
For example, the "electroslag remelting" technology we are talking about now, as a typical engineering application technology, involves an important industrial equipment-electroslag furnace during actual operation.
But unfortunately, at least for now, equipment, especially this kind of high-tech equipment, has always been China's weak point.
Especially the control system.
Tan Zhenhua doesn’t understand metallurgy, but he is from a science and engineering background. At least he knows that for such a piece of equipment, if you want it to perform precise actions under precise time, precise temperature, or other constraints, you need a A complete set of sensing, computing, dispatching, electric power, and mechanical structures can be coordinated. To manufacture such a control system, there may be dozens of disciplines and industries involved, and even hundreds of subdivisions may be involved!
This is not something that can be achieved just by leading the field of "electroslag remelting". Even strictly speaking, this system does not belong to this discipline. It should be more accurate to say that this system is "automatic". The product of the field of "control" is nothing more than its industrial application in "electroslag remelting".
In the field of
automatic control
, China’s current China is clearly far behind the international advanced level. For example, the current China’s most advanced electroslag furnace has to introduce related products from Austrian companies. To be honest, Austria’s In Western developed countries, they are barely able to reach the second-rate level. The technology and capabilities in "automatic control" are far behind the world-renowned companies in the United States, West Hans, and Gaul.
Wait a minute, as if I suddenly remembered something interesting!
Automatic Control System?
And Mr. Zhu also said just now that the first "International Electroslag Remelting Technology Seminar" was held in Pittsburgh?
There must be a reason for holding the first seminar in Pittsburgh. Well, Pittsburgh, Pennsylvania, is the core town of the U.S. steel industry. It is known as the "Steel Capital of the World". It would be reasonable to choose this place there. However, Since this conference was held in Pittsburgh and it is such an important conference that has a huge impact on the global metallurgical industry, then it is impossible for the family that controls most of the metallurgical industry in the U.S. with Pittsburgh as its base to not be mixed?
With Rockwell. The name of Douglas came to mind, and Tan Zhenhua couldn't help but put a smile on his mouth.
"Mr. Skef Mellon, it seems that we have another business to discuss. The joint venture company in Magic City will add a new business content-automatic control, but Rockwell can be ranked globally. One of the top three areas of strength!"
"Comrade Xiao Tan, what did you think of? You laughed so happy?" Li Liqing, who was sitting next to him, looked at Tan Zhenhua's expression a little strange, and couldn't help but ask.
"Oh, ah, Minister Li, I suddenly thought of some business matters just now. Well, maybe it will be useful for the further promotion and development of the "electroslag remelting" technology nationwide, so I am happy."
"Oh? What kind of business?"

In fact, it’s nothing. Last year, Rockwell and I jointly invested in a company in Magic City. At present, the main business of this company is to develop and produce related supporting equipment for the domestic new passenger aircraft project. But I think Rockwell Since you are one of the giants in automatic control, it should be no problem to engage in the automatic control system of this electroslag furnace? And considering the background of this company, they may have these technical reserves in the first place, maybe, This thing originally belonged to one of their business areas, and according to my investment agreement with them, many technologies are transferable..."
"Rockwell? Really? If I remember correctly, Mr. Cai from the Iron and Steel Research Institute in the past mentioned it to me in particular, saying that this is one of the top manufacturers of "electroslag furnace" automatic control systems. 1. The system used in the U.S. electroslag furnace is almost one-handed, that is, the asking price is very expensive and there are many export restrictions. They have to switch to Austria, which has a little backward technology but relatively loose trading conditions, after many failed communications. , But if it's a joint venture company... this is really good news."
There is unstoppable excitement in Zhu Yusen’s words, even the tone is lighter: "Although I am not particularly proficient in metallurgy, I also know that a good control system can greatly improve the level of steel smelting technology, and a good smelting process level It plays an important role in improving the quality of steel. Comrade Xiao Tan, how about it? After the meeting is over, I will introduce some of our country’s steel and metallurgical experts to you. You can discuss with them how to cooperate. , The quality of steel has a huge impact on the performance of artillery and even the tank!"
Tan Zhenhua said weakly: "Well, that, Master Zhu, you don’t need to trouble your old man in this matter. In fact, I know well Cai Qigong of the Iron and Steel Research Institute, and I have invested several in him. For the R&D project of special steel, I can go back to him by myself, but I’m sorry, I didn’t notice the tank steel and gun steel before. I will hurry up in the future... Well, actually, I also invested in a special steel factory. Ningdu..."
...
After a brief silence, Zhu Yusen took a deep look at Tan Zhenhua again, and thoughts of all sorts of thoughts turned in his mind, and he was a little confused for a while.
Taking a deep breath, he resumed his narration: "For a piece of qualified artillery steel, the completion of "electroslag remelting" is only the end of the metal smelting step. The next step is of course. It's forging."
"The forging process is the use of forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as loose as-cast metal during the smelting process. Optimize the microstructure, and at the same time, due to the preservation of the complete metal streamline, the mechanical properties of the forging are better than those of the same material. For a part such as a gun barrel that needs to work under extremely harsh conditions, the forging process is particularly Important. In the past, although large-tonnage forging machines were also available in our country, due to the service age, technical performance, and forging accuracy of these forging machines, our forging technology level lags far behind the international advanced level. The situation has been significantly improved. The 30,000-ton forging machine of Southwest Aluminum has been remodeled, and the dimensions of the forgings that can be processed, the forging accuracy, and the metal performance parameters after forging have been greatly improved. Unfortunately, The problem is that the task of this forging machine is very heavy. Most of the production capacity has been requisitioned by the Ministry of Aviation, which makes it take a long time for us to queue for the new gun barrel forging test. They are not happy to accept the batch of test pieces. By the way, Minister Li, can you coordinate with the Ministry of Aviation on this matter?"
Before Li Liqing expressed his opinion, Zhu Yusen saw Tan Zhenhua raising his hand again to ask for a speech, and couldn't help but ask: "What is Comrade Xiao Tan's opinion?"
"Well, that's right, I want to say that I should be able to help a little with this matter."
"You? Help?" A strange hunch flashed across Zhu Yusen's heart.
"Uh, um, I'm sorry, I can't be blamed for this. I really didn't know beforehand." Tan Er's face was full of sincere and sorry expressions: "I invested in the transformation project of the forging machine of Southwest Aluminum. When the meeting is over, I will immediately greet them and promise Master Zhu you to join the team."
Zhu Yusen: "..."
Co-authoring from ore to parts blank, a piece of artillery steel made a big circle, but did not get out of your Tan Zhenhua's door?
