Processing And Refining The Iron

Processing And Refining The Iron

About 95 of this iron is processed further to make steel, often by the open-hearth process or the Bessemer process, but more recently in the United States and other countries by the basic oxygen process or by an electric arc furnace. The balance is cast in sand molds into blocks called pigs. It is further processed in iron foundries see casting.

  • Steelmaking And Refining Introduction To Chemistry

    For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon. The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a

    In the electric arc furnace process, the electric arc furnace oxidizing slag is firstly produced when the iron scrap is melted and refined into steel, and then the electric arc furnace reducing slag is produced in the ladle refining furnace. Further refining of the stainless steel in the ladle furnace generates argon oxygen decarburization slag and desulfurization slag.
