Description

Using super high-chromium cast iron, which is the prime wear resistant material in the world, we adopt the technology of control solidification in the process of founding, , utilize compound alterant for modification, refine the crystalline grain, increase the toughness, improve the shape and distribution of carbides, and make the growth direction of the carbides vertical to the abrasive surface. Optimization heat treatment is adopted, thus, the hardness of the cast parts is better, so is the toughness, what’s more, the shock resistance and wear resistance are also improved. In the domain of stone crushing, we have developed plate hammers for large-sized impact breaker, consumers’ probation shows that the wearing resistance is excellent, and it could improve the operating factor of equipments
