The main advantages of high frequency heating machine

① There is no need for overall heating, the deformation of steel parts is small, and the electromagnetic energy consumption is small.

②No pollution.

③ The heating speed is fast, and the surface oxidation and decarburization of the workpiece is lighter.

④Surface hardened layer can be adjusted according to need, easy to control.

⑤The heating equipment can be installed on the machining 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 finer, and the hardness, strength and toughness are higher.

⑦After surface quenching, the surface layer of steel parts has greatly reduced thermal stress, and the steel parts have a high potential for relieving fatigue and breaking.
