ll Products Description
Chrome alloyed casting grinding steel ball (Dia.20-150mm) is widely used in cement building materials, metal mines, and other industries for powder preparation and superfine processing. The hardness reaches 45-65HRC, and the distribution of the hardness gradient is average. The property- low abrasion, good toughness and less breakage, prolongs its life, improves the productivity of the ball mill, and lowers the cost. Our quality is accord with GB/T17445-2009 standard.
Processing Technique
Intermediate frequency furnace smelting high-quality steel scrap and chromium alloy etc.
Constant temperature casting process ensuring the quality, no sonim, no pore, no mal-roundness etc.
Oil-immersed heat treatment and annealing process changing the internal organizational structure, lowering the breakage, and improving the performance.
Matter test, after the furnace test, semi-finished products and end products inspection was done by advanced spectrometer and durometer imported from Germany.
