"The sports icon of Beijing 2022 Winter Olympic Games be made into a postcard by ultra thin low carbon steel foil"
The combination of "ultra thin low carbon steel foil" and postcards not only shows the advanced level of China's steel manufacturing industry today, but also fully reflects the high-level steel manufacturing capacity of enterprises.
"Ultra thin low carbon steel foil" is also called "5G steel", which is mainly used for 5G base station signal receiver, signal transmission filter and integrated circuit board.
Entering the "ultra thin low carbon steel foil" production site of BJSG Iron and Steel Technology Group, steel making, cold rolling and other processes were carried out orderly, with the thinnest one being only 0.07mm.
The "ultra thin low carbon steel foil" production process includes four main processes: iron making, steel making, hot rolling and cold rolling, including more than 300 small processes and thousands of quality control points.
Tin plating products with high strength, thin reduction and high elongation are widely used in all walks of life
BJSG actively gives play to its advantages in equipment, process and technology, and vigorously promotes the R&D and production of ultra-thin DR materials (secondary cold rolled materials).
"After three years of scientific research, BJSG has been breaking the limit, reducing the thickness of the wide 'ultra thin low carbon steel foil' from 0.11mm to 0.07mm, reaching the world's advanced level!
"The reason why 'ultra thin low carbon steel foil' is ultra-thin is that this steel plate has high requirements for material density and other properties, as well as for full process control capability."
"'ultra thin low carbon steel foil' belongs to the ultra-thin limit product of low carbon steel. During the production process, it overcame the 'three difficulties' in the industry of' high molten steel purity, acid continuous rolling and twin stand rolling thin ', which benefited from the collaborative efforts of scientific researchers and production site technicians."
The company attaches great importance to the development of new products
From January to October 2022, the company will develop 102 new products, and multiple types of products such as zinc aluminum magnesium outer plate, pure zinc outer plate, pickling plate, galvanized automobile plate will be supplied in batches;
The strength grade of ultra-high strength steel reaches 1180 MPa, and the products such as 9Ni steel for medium and heavy plates and high strength steel for liquefied petroleum gas ships have been successfully rolled.
