Manufacturing operations of the iron and steel industry may be grouped as pig iron manufacture steelmaking processes rolling mill operations and finishing operations. A single mill is not likely to incorporate all of the many combinations and variations of these operations that are possible. Most mills specialise in the production of broad egories of steel products; in a large mill ...

Water Requirements of the Iron and Steel Industry

the iron and steel industry with respect to geographic distribution plant size and processes used. Fourteen of the installations in the iron industry were operated as mine-concentration plant combinations although in some places the distance from the mine to the concentra­ tion plant was a few miles. Only one mine and one concentration

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

Steel Manufacturing Process - Association for Iron and Steel ...

The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel scrap. The molten steel is formulated to precise chemical compositions during the secondary refining processes. The refined steel is then cast into a variety of solid shapes usually by a continuous casting method. The solidified shapes ...
