Product name: Medium chrome wear-resistant cast ball
Product Category: Medium Chrome Cast Balls
Product number: 02
Product information: Medium chromium wear-resistant cast balls refer to cast balls with a chromium content of less than 10% and greater than 5%, and the lattice types of eutectic carbides are (Fe, Cr) 7C3 and (Fe, Cr) 3C. . Its manufacturing process is similar to that of high chromium cast balls. Customers are widely distributed in metallurgy, mining, building materials cement, thermoelectric coal grinding, chemical powder and other industries.
1. The raw materials are all bearing steel scraps, which contain copper, molybdenum, nickel and other precious metal elements, which can effectively improve the matrix structure of the steel ball, make the grains more refined and the structure more dense.
2. Single refining process: All products are produced by medium frequency electric furnace, which effectively ensures the stability of the material. The content of sulfur and phosphorus in the product is extremely low, and it is not easy to peel off and deform during use. Even if it runs for a long time, it can keep bright and round.
3. The most advanced and reasonable large-scale automatic oil quenching production line is adopted for heat treatment. The hardness and uniformity of the product have reached a new height, and the hardness and toughness are maintained at a more reasonable intersection point.
4. The automatic iron mold sand-covered casting production line is used to produce wear-resistant casting balls with a diameter of more than 40mm, and the boxless molding casting production line is used to produce wear-resistant casting balls with a diameter of less than 40mm, which can achieve smooth surface and high internal and external hardness: all surfaces of steel balls have uniform internal and external hardness All indicators are better than national and industrial standards, with good wear resistance, stable product gradation, and long-term operation, which can effectively ensure high and stable production of the mill.
