The BF BOF route produces steel using raw materials such as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling and/or coating, the steel is delivered as strip,

Carbon steel Simple English , the free encyclopedia

Carbon steel, or plain carbon steel, is a metal alloy.It is a combination of two elements, iron and carbon.Other elements are present in quantities too small to affect its properties. The only other elements allowed in plain carbon steel are manganese (1.65% max), silicon (0.60% max), and copper (0.60% max). Steel with a low carbon content has the same properties as iron, soft but easily formed.
