WHAT IS STEEL MAKING PROCESS: BRIEFLY EXPLAIN

Modern steel making process uses a blast furnace for manufacturing steel It can be divided into two categories: primary and secondary Primary steel making includes “converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steel making or melting scrap steel and/or direct reduced iron (DRI) in an electric arc Steps in the Modern Steelmaking Process,Ironmaking, the first step, involves the raw inputs of iron ore, coke and lime being melted in a blast furnace The resulting molten iron also referred to as hot metal still contains 4-45 percent carbon and other impurities that make it brittleProcess monitoring of iron-making process in a blast ,Incidents happening in the blast furnace will strongly affect the stability and smoothness of the iron-making process Thus far, diagnosis of abnormalities in furnaces still mainly relies on the personal experiences of individual workers in many iron works
