The cast steel ball is a steel ball manufacturer will scrap steel, scrap iron and other waste charge, the use of medium frequency electric furnace heating, so that the charge is fully melted, in the melting process of the charge to add metal alloy to the furnace for chemical composition tempering, after the hot metal temperature to meet the requirements of the process. The steel ball produced by the qualified hot metal is called cast steel ball after it is baked, slagged, skimmed, incubated, deoxidized and statically placed into the steel ball mold
