casting girth gear

We know that girth gear is a mechanical element with teeth on the edge and capable of continuously meshing and transmitting power. The girth gear is constantly subjected to loads such as torsion and bending during work, so that its surface layer bears higher stress and constantly wear. Therefore, a good girth gear should have high strength, high hardness and high wear resistance. The importance integral quenching of girth gear is obvious.

What is the quenching of girth gear? After casting the girth gear, put it into professional quenching equipment, such as the automatic flame quenching machine used by CHAENG, which uses multiple flame guns to heat the girth geat at the same time, and keeps the girth gear constantly rotating to achieve the purpose of uniform quenching.

The purpose of the overall quenching of the girth gear is to transform the undercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness and wear resistance of the girth gear, and finally continue to meet the needs of high-strength operations and improve service life.

CHAENG is well aware of the importance of overall hardening of girth gears. It has introduced advanced quenching equipment and continuously optimized the operating characteristics of girth gears. At present, the girth gears produced by CHAENG have been applied to the rotary kiln and ball mill of domestic well-known cement companies.
