Rail Hardening Machine


Rail Hardening Machine

A. Product features

1. Induction heating does not need to heat the workpiece as a whole, but can selectively heat the part, so as to achieve the purpose of low power consumption, and the deformation of the workpiece is not obvious.

2. The heating speed is fast, which can make the workpiece reach the required temperature in a very short time, even within 1 second. As a result, the surface oxidation and decarburization of the workpiece are relatively slight, and most of the workpieces do not need gas protection.

3. The surface hardened layer can be adjusted and controlled by adjusting the working frequency and power of the equipment as required. As a result, the martensite structure of the hardened layer is finer, and the hardness, strength and toughness are relatively high.

4. After the heat treatment of the induction heating method, the workpiece has a thicker toughness area under the surface hard layer, and has a better compressive internal stress, which makes the workpiece more resistant to fatigue and breaking.

5. The heating equipment is easy to install on the production line, easy to realize mechanization and automation, easy to manage, can effectively reduce transportation, save manpower, and improve production efficiency.

6. One machine can be used for multiple purposes. It can complete heat treatment processes such as quenching, annealing, tempering, normalizing, and quenching and tempering, as well as welding, smelting, thermal assembly, thermal disassembly, and heat-through forming.

7. Easy to use, simple to operate, and can be started or stopped at any time. And there is no need to preheat.

8. It can be operated manually, semi-automatically and fully automatically; it can work continuously for a long time, or it can be used at random when it is used. It is conducive to the use of the equipment during the low electricity price discount period.

9. High power utilization rate, environmental protection and energy saving, safety and reliability, and good working conditions for workers, which is advocated by the state.
