Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm. According to different chromium content, the grinding ball can be divided into three kinds, namely low, medium and high chromium balls. The hardness of relevant balls are HRC≥45, HRC≥50 and HRC≥58 respectively, with diameter of 6 mm to 140 mm.
Due to the high chromium content in high chromium steel ball, it is easy to be in the surface of the iron liquid, so it seems that the liquid flow is poor, but it is in fact a good flow. 4 because of the high chromium casting riser is not easy to be removed, thus modeling in the form of riser should use side riser or knock off. 5.
