In order to fulfill the goal, the country initiated a mass steelmaking campaign in 1958. In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° c (2,900° f) in molten conditions.various chemical. The steel largely recognized as being the “first tool steel” was developed by robert forester mushet, a british metallurgist, in 1868 [1]. Steelmaking technology has greatly changed during the last two decades under the pressure of increased demand, new specifications and the need to reduce energy and material.
