hardening furnace

1. There is no need to heat the workpiece as a whole, but it can be selectively heated locally, so the power consumption is low and the deformation of the workpiece is small.

2. The surface hardening layer can be regulated by adjusting the working frequency and power of the high frequency quenching machine. Therefore, the martensite structure of the hardened layer is finer, and the hardness, strength and toughness are higher.

3. After heat treatment by induction heating, there is a thick ductile area under the surface hard layer, which has a better compressive internal stress, so that the anti fatigue and breaking ability of the workpiece is higher.

4. The heating speed is fast, and the workpiece can reach the required temperature in a very short time, even within 1 second. Therefore, the surface oxidation and decarburization of workpieces are light, and most workpieces do not need gas protection.

5. It is easy to be installed on the production line, easy to realize mechanization and automation, easy to manage, and can effectively reduce transportation, save manpower and improve production efficiency.

6. It is easy to use, easy to operate, and can be opened or stopped at any time. There is no need to preheat.

7. High utilization rate of electric energy, environmental protection and energy saving, safe and reliable, and good working conditions for workers are advocated by the state.

8. It can be operated by hand, semi-automatic and full-automatic; it can work continuously for a long time, and it can also be used immediately. It is conducive to the use of equipment in the period of low electricity price.

9. The high frequency quenching machine can not only complete the heat treatment processes such as quenching, annealing, tempering, normalizing, quenching and tempering, but also complete the welding, melting, thermal assembly, thermal disassembly and thermoforming.
