The main advantages of induction heating
①It is not necessary to heat the whole, the deformation of the workpiece is small, and the power consumption is small.
② No pollution.
③The heating speed is fast, and the surface of the workpiece is lightly oxidized and decarburized.
④The surface hardened layer can be adjusted according to the need, easy to control.
⑤The heating equipment can be installed on the mechanical processing production line, which is easy to realize mechanization and automation, easy to manage, and can reduce transportation, save manpower and improve production efficiency.
⑥ The martensite structure of the hardened layer is fine, and the hardness, strength and toughness are high.
⑦The surface of the workpiece has a large compressive internal stress after surface quenching, and the workpiece has a high resistance to fatigue fracture.
