steel production process

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

    The 6 Steps To Modern Steel Production Explained

    There are two main methods for making steel and these are Basic Oxygen Steel making (BOS) and Electric Ark Furnaces (EAF). BOS methods for example involve adding scrap (recycled) steel to the molten iron when in the furnace. Oxygen is then forced through the liquid (the Bessemer process) to cut the impurities in the molten metal down to 0.5% -1.5%

    Introduction of pneumatic steelmaking process to steel production. As a major development of the steel production, steelworker called Benjamin Huntsman introduce a method to melting blister steel in clay crucibles at a high temperature (1,500 0 C to 1,600 0 C) using coke as a fuel in 1751. In 1855, Henry Bessemer introduced the pneumatic steelmaking process for smelting iron. air was blown from the bottom of the
