induction heating main advantages
The main advantages of induction heating are: no overall heating, small deformation and small energy consumption.No harm, no harm.The heating speed is fast and the surface of the workpiece is oxidized and decarburized.The surface hardening layer can be adjusted according to need and easy to control.The heating equipment can be installed on the machining production line, easy to mechanization and automation, easy to manage, and can reduce transportation, save manpower and improve production efficiency.The hardness, strength and toughness of the martensite are relatively high.The surface of the workpiece has large compressive internal stress and the workpiece is more resistant to fatigue and breaking.
Induction heating heat treatment also has some disadvantages.Compared with flame quenching, induction heating equipment is more complex and has poor adaptability. It is difficult to guarantee the quality of complex parts with complex shapes.
Induction heating is widely used in gear, shaft, crankshaft, CAM, roll and other workpiece surface quenching, the purpose is to improve the wearability of these workpieces and the ability to resist fatigue break.The rear axle of the car is hardened by induction heating surface, and the fatigue cycle of the design load is about 10 times higher than that of the adjustment treatment.
