Effects of Heat Treatment Process on Microstructure and Properties of High Chromium Grinding Ball
/in Grinding media balls, Heat Treatment Process, Producing grinding ball process /by Sara WuABSTRACT: 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 […]
Understanding of abrasive hardness, carbides and wear resistance
/in Mines /by Sara WuAbout hardness, carbides and wear resistance? 1. Hardness directly reflects the wear resistance of the product, the higher the wear resistance, the higher the hardness, with the Rockwell hardness “HRC“.
The types of Surface Heat treatment
/in Heat Treatment Process /by Sara WuChemical Heat Treatment-a heat treatment process in which a metal or alloy is placed in an active medium at a certain temperature so that one or more elements penetrate into its surface to change its chemical composition, structure, and properties. Common Chemical Heat Treatment Process: carburizing, nitriding, carbonitriding, aluminizing, boronizing and so on. The aim […]
