Moulding process---pouing when the molten iron temoerature reaches
1500 C,using the teoperature difference between moletn iron and the
molds.in this way,the ball can achieve internal organization
of grain refinement and be moredense.menanwhile,the carvide is
radially arranged .and such carbide is embedded in the matrix
again during grinding process,forming hatd layer
continously,so that the hardness and toughness is maintained to a
reasonable range,greatly improving the toughness and hardness of
the grinding balls.
