why do gears have to be hardened
Advantages of gear quenching: after quenching, the hardened layer martensite microstructure is fine, hardness, strength, toughness are higher, in use is not easy to be worn, deformation.
The gear quenching process is a combination of rapid heating and immediate cooling. The surface of the steel to be processed is quenched by rapid heating, and the surface layer is hardened to martensite only when the unequal heat is transferred to the center, the center is still the original non-quenched plastic, toughness better annealing (or normalizing and conditioning) structure.
Gear quenching can be used Guoyun brand high frequency induction heating equipment, the equipment can be installed in the machining line, easy to realize mechanization and automation, easy to manage, and can reduce transportation, save manpower, increase production efficiency
