nm450 steel plate manufacturer The company products are exported to 70 countries and regions

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.
