quenching and tempering process

Defects of quenching & tempering and Prevention

In the heat treatment process, the reject rate caused by the quenching process is usually higher. This is mainly in the quenching process, and at the same time, the formation of greater thermal stress and structural stress, in addition, it is easy to be exposed in the quenching and tempering process because of the inherent […]

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 […]

The types of Surface Heat treatment

Chemical 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 […]

What is wear-resistant Grinding Ball Heat treatment?

The so-called heat treatment is through the high chromium wear-resistant grinding ball heating, heat preservation and then to the cooling process, after such a process, the wear-resistant grinding ball internal structure will have a certain change to achieve the desired performance.

Study on microstructure and properties of high chromium series wear-resistant Cast Iron Grinding Ball

Based on the effect of Cr in Cr-based WEAR-RESISTANT CAST IRON, three kinds of wear-resistant cast iron grinding balls with diameter of 110mm and different Cr content were designed by means of metallographic technique, electron microscope technique, TEM technique and X-ray diffraction technique, the macro hardness, microhardness, impact toughness and wear properties of the material […]
