National Development and Reform Commission: operation of steel industry from January to November 2022

Steel production has declined. According to the data of the National Bureau of Statistics, the national production of pig iron and crude steel from January to November was 795.06 million tons and 935.11 million tons respectively, down 0.4% and 1.4% year on year respectively.

Key metallurgical technology and industrialization of high-quality bearing steel based on non-aluminum deoxidization process

Bearing steel is an important manufacturing material for basic parts of mechanical equipment, which is widely used in military industry, aerospace, transportation and other fields. With the rapid development of the manufacturing industry, the quality and service time of mechanical equipment have increased significantly, which puts forward higher requirements for the fatigue life and quality stability of bearing steel. At the end of the 20th century, the development of clean steel smelting technology promoted the improvement of the quality of bearing steel. The total oxygen content of bearing steel decreased from 30 ppm to less than 5 ppm, and the fatigue life increased by 100 times; With the improvement of metallurgical technology and equipment capacity, the total oxygen content of bearing steel has been continuously reduced. At present, advanced enterprises at home and abroad have been able to stably control below 5ppm; It is generally believed internationally that when the total oxygen content in bearing steel is less than 5ppm, the sulfur content is less than 20ppm, and the titanium content is less than 10ppm, it reaches the ultra-high purity level.

Add Masteel, Zhongtian Steel, Donghai Special Steel and Rizhao Steel! 66 steel enterprises have completed the publicity of ultra-low emission transformation!

Since August 2020, the China Iron and Steel Industry Association has carried out the publicity work of ultra-low emission transformation and evaluation and monitoring progress of iron and steel enterprises. Up to now, 66 enterprises have been publicized on the website of the Steel Association.

China Baowu Southwest (Industrial) Headquarters Project started

China Baowu Group has four projects in Dadukou, including the Southwest Headquarters of China Baowu, the China Iron and Steel Industry Museum, the Southwest New Material Research and Development Center of China Baowu Central Research Institute, and the Chongqing Campus of Baowu University. China Baowu Southwest (Industrial) Headquarters is an additional project built on the basis of Chongqing Industrial Culture Expo Park according to the "Five Ones" strategic cooperation framework agreement signed by Chongqing and China Baowu Group.

Current situation of steel industry: "three high and three low"! High output, high inventory, high cost! Low price, low demand, low profit!

Investor: How does the company view the loss of most steel enterprises in the industry in the third quarter? Does the company calculate how much the industry concentration will increase, which will help Chinese steel enterprises get reasonable profits in the industry chain? What does the company think of industry merger and reorganization?

Metallurgical function of tundish in steelmaking process

The tundish is a refractory container used in steelmaking and continuous casting. It first receives molten steel poured from the ladle, and then distributes it to each mold through the tundish nozzle.

The birth of spring machine promotes the wider application of spring

For spring, spring machine, spring coiling machine, spring grinding machine and other spring mechanical equipment, you may rarely see them on the market, but the spring is within your reach. It is just that it is too inconspicuous to attract your attention. It is hidden in the ballpoint pen you write. It can always help you jump in and out of the pen refill. Take it apart and look at it. It is on the pen refill, the small spring, There is no substitute. If there is no spring machine for ballpoint pens, the price of ballpoint pens will not come down, and it is difficult to meet the needs of people for this kind of ballpoint pen to the maximum.

Development characteristics of spring machine abroad

More convenient operation. For example, the linear editing function allows users to easily adjust the number of coils, free length and wire feeding speed of the spring, and can display different parameters in different colors;
