Medium Chrome Cast Ball
Brand ZW
Product origin Shandong, China
Delivery time 7 days
Supply capacity 6000 tons per month
The surface hardness of the cast wear-resistant steel ball can reach 65HRC, and the hardness gradient distribution is average, with low wear, good toughness and less breakage. The product quality is not lower than the GB/T17445-2009 standard. It can improve the specific surface area of cement and the recovery rate of mine concentrate, improve the production capacity of the mill, extend the service life of the mill liner, and greatly reduce the production cost of the enterprise.

Raw material control of cast steel ball
1. Large channel steel, angle steel and scrap steel are selected as raw materials, and raw materials are strictly controlled;
2. Add high carbon ferrochrome, low carbon ferrochrome, ferromanganese alloy, copper, ferromolybdenum, ferronickel, ferrotitanium, rare earth and other alloys according to the needs of different products; The actual content of each alloy will be rechecked in our laboratory.
3. Different alloys and scrap steel shall be stacked in different areas and labeled
