The surface of the cast grinding steel ball is not allowed to have the casting defects such as the crack, and the obvious gas porosity, inclusion, shrinking cavity, cold shut, elephant skin, etc. It is not allowed to have the shrinkage cavity, shrinking porosity, gas porosity, inclusion, and other cavity defects on the section including plane pasting through the pouring gate and the ball centre.
hematite ball mill of WISCO, and the results of eight-month test in wet grinding environment have proved that the service life of the bimetal composite liner is three times as long as that of the alloyed steel liner. Key words: bimetal liner; liquid-liquid composite process; lost foam casting; high Cr white cast iron
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.Since then, "continuous casting" has evolved to achieve improved yield, quality ...
Aimed at the work conditions and the failure of the grinding ball in ball grinding, High chromium cast iron with the characteristics of long service life, high abrasion resistance and good shock resistance must be chose in the ball grinding . The best mixture ratio of chemical compositions was pointed out, and the production technological process by using die cast is introduced.
Now the mill steel ball on the market can be divided into two types according to the manufacturing process technology: Casting and forging. But the wear degrees are not the same. Due to crushing, ball need good wear resistance and toughness, which usually made of alloy steel, high manganese steel, cast iron and other materials and with forged or casted once-forming method.

(4) If using the semi-autogenous mill, the large ball with the diameter of 100-150mm can not only reduce the unit consumption, but also increase the handling capacity, but as a result of the casting process defects, the breakage rate of cast ball is much higher than the forged ball.
Characteristics 1. Adopts chilling process: The mold design uses the chilling process, which takes metal mold to produce casting grinding ball (grinding media) and then chilled in high temperature and low molten steel. 2. Makes balls inner structure more refined and close.
Method of balls rolling on ball- rolling mills is one of the most modern production methods. Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to ...
