12.5 Iron And Steel Production

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Introduction to steel making processes

Apr 16, 2016  Steelmaking is a process of selective oxidation of impurities i.e. reverse of iron making. During steelmaking impurities like C, Si, Mn, P are oxidized to their respective oxides and eliminated either as gas or as liquid slag. Other impurity ‘S’ can be minimized in reducing condition by a slag-metal interface reaction. 5.

Steelmaking Process - an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
