Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved to meet the ...

Steel mill with two arc furnaces. Steelmaking is the process of producing steel from iron ore and/or steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Currently in the 105110 million tons per year range, it is expected to increase by four to six million tons by the Year 2000. Much of that demand for steel will be met by the booming minimill industry. EAFs are expected to ship 14 million tons of hot rolled bands and related products in the Year 2000. Contrast that with three million tons ...

25925. 25925. A Mini Steel Mill or MiniMill as they are referred to, is a Mill which manufacturers steel products from scrap metal. Unlike an Integrated Steel Mill, which produces new steel from iron ore and various other additives in a blast furnace, a Mini Mill melts and refines scrap steel using one or more Electric Arc Furnaces (EAF's).

Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufacturing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is converted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace (EAF ...
