Casting Steel Ball

 

Casting steel balls are made of scrap steel as the main material, adding various alloying elements to melt into molten iron, and then pouring into molds. The most important component is chrome, which can be divided into low chrome casting balls, medium chrome casting balls and high chrome casting balls according to the different chrome content. Due to the production process, there are pouring ports and rings on the surface of cast steel balls. Cast steel balls are resistant to grinding and have uniform internal and external hardness. They are widely used in cement plants, aluminum power plants, mines, building materials and other industries.
