Product Description
Medium Chrome steel ball casting grinding media
Description of Grinding chrome Steel Balls
Casting grinding steel balls are widely used in cement building materials, metal mines, and other industries for powder preparation and superfine processing. The hardness reaches 65HRC, and the distribution of the hardness gradient is average. The property-low abrasion, good toughness and less breakage, prolongs the life of steel balls, improves the productivity of the ball mill, and lowers the cost. Our quality is accord with ISO9001 standard.

1. Over 20years Professional casting grinding balls manufacturing experience, deserves your trust.
2. High performance/price benefits our customers.
3. ISO9001 certified company, advanced oil quenching and heating production line, together with advanced testing machines to ensure the quality.
4. Skilled sales & service team in Shanghai branch can provide timely good service.
5. 200 thousand Tons annual production capacity can provide short L/T.
Processing Techinque of Grinding chrome Steel Balls
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 Shimadzu.

Quality Control
Adopting the bearing steel scrap raw materials, containing copper, molybdenum, nickel and other precious metal elements, which effectively improve the product's basic organization, refine grain further, and compact the organization. Besides, the sulfur and phosphorus content is extremely low, which makes sure that the products avoid peeling and deforming during use. Also, the surface is smooth and rounded.
Adopting single smelting process. All products use the intermediate frequency electric furnace processing, which effectively ensure the stability of the melting temperature.
Adopting heat treatment production lines-- advanced automatic pusher oil quenching, which has a good hardenability. The technique greatly improves the uniformity of product hardness, and makes the relationship between hardness and toughness improved, so as to improve the wear resistance of the product.
Adopting spectrometer during matter test, after furnace test, and semi-finished products and end products inspection, which provides precise chemical components analysis of the raw materials.
