cast grinding balls
1. Introduction of cast grinding ball
casting grinding ball—Introduction
Casting steel ball (casting grinding ball) is made of the scrap steel, scrap metal and other waste scrap which is melted by the heating of intermediate frequency electric furnace. In the melting process, the amount of precious metal alloy (such as iron, manganese, vanadium etc.) is added into the furnace for chemical composition. Then pour the qualified molten iron into the production line mold of steel ball when temperature of molten iron reaches more than 1550℃and the molten iron meets other technology requirements.
Casting Steel Ball—Classification:
High chromium alloy casting ball, medium chromium alloy casting ball, low chromium alloy casting ball
2.Advantage of cast grinding ball:
High performance and low cost, wide application range, especially in cement industry as the representative of the dry grinding field
Casting Steel Ball—Production Process Flow of casting grinding ball:
Inspection of raw materials----Materials ratio---Heating and melting of Intermediate frequency furnace---Pouring into mold--- Quenching----Tempering----Testing---Package
Quality Detection and Standard of casting grinding ball
