Zhao Qingshan invited Director Xu to eat hot dry noodles, and Director Xu said Xiao Zhao, you must contact me when you go to Henan, and the stewed noodles are waiting for you.

The representative of Baosteel said: "Xiao Zhao, when you go to Shanghai, remember to look for me, scallion oil noodles are waiting for you." ”

Angang representative: "Baked cold noodles are waiting for you." ”

Guanggang representative: "Wonton noodles are waiting for you." ”

Heavy steel representative: "Small noodles are waiting for you." ”

The representative of Shougang is Zhao Qingshan's senior brother in Yanjing Iron and Steel Academy: "There are all kinds of noodles in the capital, Xiao Zhao, see you in Wudaokou." ”

Through this large-scale dating meeting, Zhao Qingshan made many friends, from the south to the north, from all walks of life, miscellaneous conversations, and mutual communication.

The symposium ended on Friday, and Saturday was devoted to a full day of production site research. Jiang Gang, as the host, arranged everything.

"One meter seven rolling mill system" is the focus of the visit, three factories and one workshop are too large, even if the guests are overlooked, they can not complete the three factories and one workshop in one day.

Therefore, the method of "professional counterpart team" was adopted, and the Jianggang personnel took the guests of each team to wander around the workshops of each factory.

Zhao Qingshan is the captain of a small team, and the guests he led are Director Su of the Metallurgical Department, Gong Gong, a senior engineer of Baosteel Plant, Yang Deputy Director of TISCO Technology Department, and Director Xu of Wuyang Steel Plant.

"This is our Jianggang hot rolling mill, everyone can look at it casually, you can ask me if you have any questions, but you can't take pictures and videos, please understand. Zhao Qingshan took the guests to the hot rolling mill and explained the rules clearly.

"We don't even have the equipment to take pictures and videos, so Xiao Zhao can rest assured. Vice Minister Yang of TISCO took out his trouser pockets with both hands, indicating that he was clean and did not carry private goods.

"Xiao Zhao, a comrade, has a strong sense of secrecy, and he wants it. Director Su spoke of Trump, and he understood and supported the strict secrecy system adopted by Jianggang.

"I see. ”

Medium. ”

Baosteel Gong Gong and Wugang Director Xu both said that they only watched, listened, and only moved their mouths, and would never do anything.

"Thank you for your understanding, so let's start visiting the hot rolling mill. Jianggang hot rolling mill is very young, with the new one meter seven rolling mill system, there are currently 20 departments, 14 workshops, more than 3,000 employees, a total of 4,924 sets of equipment, the core equipment includes 3 step-by-step heating furnaces, a set of one meter seven continuous hot rolling mills, 5 hot rolled steel coil finishing processing lines, oh, this is the No. 3 heating furnace, I invented the self-developed coating used in the No. 3 furnace oriented silicon steel firing ......"

Zhao Qingshankou Ruohanghe is off the manuscript data, thanks to his business skills.

The four guests had a clear purpose, they came to see the No. 3 furnace, and the subsequent one-meter-seven continuous hot rolling and finishing process.

"Our magnesium oxide-chromium trioxide self-developed coating has been industrialized for several months on furnace No. 3, and the effect is very good, with a single furnace repair cycle slab heating capacity of 7,000 tons, and will not affect the performance of oriented silicon steel, creating economic benefits of more than 4 million yuan per year. This patent was exported to Nippon Steel, and one or two heating cycles were used at their Hitohata Plant, Nagoya Plant, and Yawata Plant, and it is reported that the actual effect of this paint at Nippon Steel Plant is even better than that of our Jianggang ......"

Zhao Qingshan truthfully explained the effect of his patent, and he knew that Baosteel, TISCO, and Wugang were very interested in his self-developed coatings.

"I have to admit that even if the equipment, technology, and raw materials are exactly the same, Dongying people do better than us in terms of system management, lean production, and cost reduction. Director Su said, he added: "Jianggang's self-developed magnesium oxide-chromium trioxide coatings are exported to Dongying, which not only generates foreign exchange, but also establishes a positive image of technological innovation of Chinese iron and steel enterprises. Since Nippon Steel has expressed satisfaction with its use, it can be expanded to domestic brother steel mills. ”

On behalf of the Ministry of Metallurgy, Director Su put forward a suggestion that, of course, the main responsible party for technology exchange and business transactions between enterprises is the enterprise.

After sufficient on-the-spot appearance, Vice Minister Yang regretted: "We TISCO began to make oriented silicon steel very early, and we started to do it in the 67s. But our equipment technology is quite different from Jianggang, after all, we don't have a meter seven. Jianggang's self-developed magnesium oxide-chromium oxide coating is a good thing, but it's a pity that we can't use it. ”

"Although the heat treatment equipment process of our Wugang is not as advanced as Jianggang's 1.7 meters, there are still many similarities. Silicon steel we are also doing Wugang, but they are all 50W series of silicon steel, Xiao Zhao's invention of the paint does work, but each steel mill has its own actual situation, hey, we Wugang has to sigh. "Director Xu is a little inferior, in front of Jianggang, Baosteel, and TISCO, they are the younger brothers.

50W is the first half of the silicon steel grade, 50 represents the thickness of the silicon steel sheet 0.5mm, and W represents the non-oriented silicon steel.

The second half of the 50W series is usually 230~1600, which represents the iron loss value.

Looking at the grade, you can see the value of silicon steel, Q = oriented silicon steel, Q is worth more than W.

If both are Q or W, the higher the magnetic inductance, the thinner the thickness, and the lower the iron loss value, the more valuable the silicon steel sheet.

TISCO and Wugang automatically withdrew, and Gong Gong of Baosteel was thirsty for paint: "There are too many similarities between Baosteel and Jianggang, so I won't list them one by one." Our Baosteel currently produces oriented silicon steel including B30Q140, B35Q145, B35Q155, Zhao Gong, find a conference room, let's talk in detail. ”

B stands for Baosteel, Gong Gong said that these grades of oriented silicon steel, Jianggang have products with similar properties, and replacing B with J is the grade of Jianggang.

Jianggang and Baosteel are not only competitors, but also close brothers, both of whom are sons of the Metallurgical Department.

For a period of time, the supply of iron ore raw materials in Jianggang was insufficient, resulting in insufficient billet production.

Without billets, steel products cannot be processed, and the impact is great.

Baosteel sold a large number of its own high-quality steel billets to Jianggang at a very low price, which solved Jianggang's urgent need.

In order to achieve the goal of "double 7 million tons", Jiangshan Iron and Steel needs to build a new blast furnace, and at the same time, Baosteel also needs to increase production and expand capacity, and also need to build a new blast furnace.

Jiangshan Iron and Steel dispatched the country's most powerful blast furnace construction team, the "Second Team of Jianggang Construction Company", to Baosteel to support the construction of Baosteel's new blast furnace, resulting in a delay in the construction of Jiangsteel's new blast furnace.

There are too many technology exchanges and other cooperation projects between the two mega steel mills to go into details.

The two of them gave each other their hardest scales, probably such a relationship.

Zhao Qingshan's self-developed coating, there is no reason not to take care of Baosteel.

There are so many steel mills in China, as far as this special oriented silicon steel protective coating is concerned, only Baosteel has the strength and the most suitable to be taken care of.

The sky is big but suitable, and the right love is true love.

Zhao Qingshan replied: "Gong Gong, I don't think it's a big problem, but I still have to report to my leader, why don't you stay in Jianggang for a few more days?"
