How much do you know about the characteristics of medium frequency induction heating equipment for bearing heating?

Features of medium frequency induction heating equipment for heating bearings

1. Fast heating speed and high efficiency

Generally, heating in a furnace relies on three heat transfer methods: radiation, convection and conduction to heat parts or blanks. These are all indirect heating and the heating speed is slow. Induction heating of bearing heaters relies on direct heating of induced eddy currents. The energy transfer is in the form of electromagnetic waves, so it is less affected by external interference and has less energy diffusion, so the workpiece can be heated to the expected temperature in a short time. , so it has the remarkable characteristics of fast heating speed and high heating efficiency, which is impossible to achieve by general indirect heating.

2. Save electricity and reduce energy consumption

For example: the induction rapid heating of workpieces is heated by coal, petroleum products or gas. Not only is it a serious environmental hazard, but also because in most factories, waste heat is not recycled, and the thermal efficiency is about 8%-20%. If induction heating is used, the thermal efficiency can reach more than 40%.

3. Bearing heater has high heating quality

During indirect heating in a general furnace, due to the slow heating speed and long heating time, serious oxidation and decarburization of the surface of the parts or blanks will occur. If the heating is too fast and the temperature difference between the surface and the core is too large, severe thermal stress may occur, causing the parts to deform or even crack. However, long heating time may cause serious grain growth (referring to forging heating), causing difficulties in subsequent heat treatment and even causing adverse consequences. Some of the above problems are difficult to overcome. The bearing induction heating time and temperature are easy to control, which can ensure a small temperature difference, which is beneficial to improving quality, increasing yield and profit, and the heating quality can also be significantly improved.

4. Easy to operate and use, safe and reliable.

When using a general fuel furnace for heating, the heating and cooling processes are very long and a large amount of heat energy is wasted. The auxiliary time required for induction hot start and stop is very short, and the operation is simple, safe and reliable.

5. Easy to implement mechanization and automation

It is difficult to achieve mechanization and automation in a general furnace, but induction heating is easy to achieve. Due to its high heating efficiency, the parameters of the heat source during processing are mainly the power and frequency of the power supply. Therefore, only by realizing mechanization and automation can the high-efficiency characteristics of this heating method be fully utilized. In recent years, dynamic control technology has developed rapidly, automated instruments have been constantly updated, and electronic computer control of the induction heating process has emerged.

6.No pollution

The heat source of induction heating of bearing heaters and gear heaters is electric energy. No harmful gases and pollutants are produced during heating, and they are environmentally friendly heat sources.

7. Can heat workpieces with complex shapes.

8. The operation occupies a small area and the production efficiency is high.

9. Heated assembly, the temperature is uniform, and the manufactured products are of good quality.
