Casting Grinding Steel Ball

Technical Description of Casting Grinding Steel Ball
Casting Grinding Steel Ball is made from well-matched scrap iron and ferrochromium, heated by medium frequency electric furnace and smelted into molten iron. When the temperature of molten iron reaches into 1500°C, then pouring it into ball mould. Casting Ball is formed. Then use Sand Slinger to do Surface Treatment for Casting Balls. Last, heat treatment of casting ball. Feed the Oil Quenching Production Line with casting balls, and heated up to 960°C. Keep casting balls in the machine for 6 hours. Once finished heating, then put the balls into special quenchant(a kind of quenching liquid). Keep the Balls fully sink into the quenchant for 10 minutes. Grinding Steel Ball with the above manufacturing process is called Casting Grinding Steel Ball.

Technical Desciption of Forged Grinding Balls
Forged Grinding Ball is made from steel, heated by energy-efficient industion bar heating furnace. After heating, then forged by air hammer. Chromium content contained in forged grinding ball is about 0.1% to 0.5%, and carbon content below 1.0%. Through independently-developed water quenching heat treatment production line and scientific heat treatment process, the Forged Grinding Balls have a higher hardness(more than 56 HRC surface hardness; more than 30 HRC core hardness), high impact toughness and unbreakable. Under various poor working conditions, the Forged Grinding Balls can keep stability.
