As we know that a large gear is a kind of mechanical component that has teeth on the edge of the wheel body and can continuously mesh and transmit power. The large gear is constantly subjected to the load of torsion and bending during operation, and the surface layer bears higher stress. So the excellent large gear should have high strength, high hardness and high wear resistance. The importance of the overall quenching of the large gear is self-evident.

What is the quenching for large gear? After casting the large gears, put them into professional quenching equipment, such as the automatic flame hardening machine used by Great Wall Steel Casting (CHAENG), using multiple flame guns to simultaneously heat, and keep the large gears rotating continuously to achieve the purpose of uniform quenching.

The purpose of the overall quenching of the large gear is to transform the supercooled austenite into martensite or bainite, obtain the martensite or bainite structure, and then mix the tempering at different temperatures to greatly improve the strength of the large gear. , hardness and wear resistance, and ultimately meet the high-strength operation requirements and improve the service life.

CHAENG knows the importance of the overall quenching of large gears, and introduces advanced quenching equipment for the casting of large gears, and continuously optimizes the operating characteristics of large gears. At present, the large gears of CHAENG have been applied to the ball mills and rotary kilns of many cement plants like Tianshan cement, Meng Electric Cement Group.
