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
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to …

There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in combination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which ...

mill waste or pre-chipped from debarked roundwood elsewhere, or as waste sawdust in the case of some pulping processes. If roundwood is used, it is first debarked, usually by tumbling in large steel drums where wash water may be applied. The debarked wood bolts are then chipped in a chipper if the pulping process calls for
However, in hot-rolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. Inasmuch as the steel indus try generally considers all water used in rolling mills as cooling water, it is reported as such in this report.

steel scrap raw materials are collected and distributed by brokers, collectors, and dealers in the ferrous scrap industry to steel mills and foundries. Steel mills can be divided into integrated mills, which produce pig iron from iron ore and refine the pig iron to steel, and nonintegrated mills, which use scrap as their primary raw material.
