Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, A514 Gr K alloy steel plate 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.
The European steel industry has been hit hard by the coronavirus pandemic. The auto industry, the second largest consumer of A514 Gr K alloy steel plate and so on steel, was temporarily shut down, while construction, the biggest consumer, slowed sharply in the UK in the last week of March, experts reported. It can be expected that the current crisis (which is still intensifying) will have the same or even greater impact on the steel industry as the global financial crisis.
Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, A514 Gr K alloy steel plate. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
The company mainly supply mild A514 Gr K alloy steel plate steel plate, alloy steel plate, boiler plate, corten steel plates for railway, marine, automotive, home appliances, shipbuilding, construction, machinery manufacturing and oil tank projects. While accelerating the development of the main steel industry, the company adheres to a diversified development strategy and actively develops the other industry like household products, face mask machine, precision casting producing, steel structures, and heavy plates processing service.
