Ball bearing quenching by medium frequency induction heating machine

The ball bearing is an important part of the car, which requires a certain strength and wear resistance, as well as a high fatigue strength, stable size during the working process, and can withstand a certain impact, so it is required to be quenched and heat treated on the surface. For the heat treatment of ball bearings, we mostly use medium frequency induction heating machines. At present, Zhengzhou Gou's equipment is the most popular in the market. This equipment is not only very popular in China, but also very popular in many foreign countries and regions.

Most of the ball bearings are made of 45 steel, the surface hardness is 48-58HRC, and the depth of the hardened layer is 3-6mm. We usually use an 8KHz medium-frequency induction heating machine with an output power of 200kw, the speed of the parts is 150r/min, and the heating time is 5s. After heating, all of them are cooled in water at the same time, and the sensor adopts a partial profiling sensor, and the effect is very good.

Performance characteristics of Zhengzhou Gou's medium frequency induction heating machine:

1. The efficiency of the whole machine is high, and the efficiency of the whole machine can reach more than 85%.

2. High reliability, with a unique circuit design, the power module unit used constitutes the system, even if a single power module unit is damaged, it will not cause equipment work interruption, so that the reliable operation of the equipment has been substantially improved.

3. The output power is easy to adjust, the response speed is fast, the control is accurate, and the heating conditions can be selected arbitrarily.

4. Since all the energy-saving devices are used, the life of the whole machine is long.

5. Energy saving: Compared with the electronic tube high-frequency induction heating equipment of the same power level, it can save more than 50% of electricity and more than 70% of water.

6. Low failure rate, low working voltage (380V), high safety factor, convenient use, inspection and maintenance.

7. Simple structure, small footprint and light weight.

8. Realize large capacity, and the power of a single machine can reach more than 200kW.
