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.
Wear Resistant Steel Ball 65Mn Chrome Alloyed Casting Grinding Steel Ball
The matrix of nodular iron is changed through isothermal quenching. It embodies high strength, super high toughness and wear-resistance. It has been widely applied in mining industry and is fit for mill.
