10.Technological Characters of Cast Steel Ball

(1)Chemical Composition Matching

The best configuration of various alloying elements can combine the ball's hardness and toughness at their best.

(2)Melting and Pouring Process

All cast steel balls are produced by intermediate frequency electric furnace. The purity and stability of materials are effectively ensured after uniform temperature conditioning and twice hot metal purification.

(3)Temperature Control Process

Our techinical workers duly master the proper pouring temperature, mold temperature, so that the products achieve a good state of body tissue during the transition from liquid to solid states.

(4)Moulding Process

Pouring when the molten iron temperature reaches 1500°c. 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, so forming hard layer. Thus, it greatly improves the toughness and hardness of the grinding balls.

(5)Heat Treatment Process

We have two sets of heat treatment production line. One is oil quenching, and another is air quenching. The steel grinding balls has the characters of high hardness, good toughness, low wear rate, low break rate etc. through tempering.
