Lingyuan iron and steel group co., ltd. main products.

The main raw materials for iron and steel production include raw and finished iron ore, manganese ore, chrome ore, limestone, refractory clay, dolomite and siderite, artificial lump ore, ferroalloy, coal washing, coke, gas and coal chemical products, refractory products and carbon products. Iron and steel products are the general name of metal products based on iron (Fe), and their daily forms include iron, crude steel, steel and ferroalloy. Because ferroalloy is mainly used as deoxidizer and alloy additive for steelmaking in the production process of iron and steel industry, ferroalloy is usually listed as the main raw material for iron and steel production rather than steel products in management and statistics. In addition, steel wire, wire rope, stranded wire, iron wire, nails and other steel wires and their products belong to the reprocessed products of steel products, not metal-based products. So statistically speaking, steel products only include pig iron, crude steel and steel products. Iron is the "primary product" of steel products, and steel can be obtained after further smelting. The two are mainly distinguished according to the carbon content in iron-based products. The direct product of iron smelting is crude steel (called billet or ingot in solid state), which is processed into steel by casting, rolling, forging and extrusion. Steel is the main form of the final product provided by the steel industry for social production and life. Due to the variety and specifications of steel products, in order to meet the needs of statistics, production, marketing and inventory management, steel products are usually divided into four categories: excellent materials (also known as profiles), flat steel (also known as strip steel or steel plate), steel pipes (also known as pipes) and others.
