High Chrome Alloyed Grinding Cylpebs

Grinding cylpebs are widely used in cement, mining and chemical industry etc.. The hardness reaches up to 64HRC(the surface and inner hardness tolerance with in 2HRC), which makes the high wear-resisting property. In addition, the distribution of the hardness gradient is average. The property- low wear rate, good toughness, prolongs its life, improves the productivity of the ball mill, and lowers user’s cost. Our quality is accord with GBT17445-2009 China national standard.

 

Intermediate frequency furnace smelting high-quality steel scraps and mix chromium based on requirements.

Constant temperature casting process ensuring the quality, no solid nonmetallic impurity, no pore, etc.

Oil-immersed quench harden treatment enhance the hardness, Annealing process changing the internal organizational structure, lowering the breakage, and improving the performance.

After the Pre-furnace test, semi-finished products and finished products inspection was done by advanced spectrometer and durometer imported from Germany.
