Process features of cast iron balls:
Moulding process---pouring when the molten iron temperature reaches 1500 C,using the temperature difference between
molten iron and the molds.in this way,the ball can achieve internal organization of grain refinement and
be more dense.meanwhile,the carbide is radially arranged .and such carbide is embedded in the matrix
again during grinding process,forming hard layer continously,so that the hardness and toughness is
maintained to a reasonable range,greatly improving the toughness and hardness of the grinding balls.
