Effects of Heat Treatment Process on Microstructure and Properties of High chrome Grinding Ball

Effects of Heat Treatment Process on Microstructure and Properties of High Chromium Grinding Ball

ABSTRACT: The heat treatment process of high chromium grinding ball produced by sand coated iron mould casting process was researched. Shrinkage and porosity defects have not been discovered after cutting along the diameter of grinding ball. The grinding ball in cast state has poor mechanical properties. Mechanical properties of grinding ball significantly increase after heat treatment After heat […]
