Medium frequency induction heating machine heats the outer circle and the inner hole at the same time, what is the sensor like?

As an important part of the medium frequency induction heating machine, the inductor is an essential part for heat treatment of the workpiece. The medium frequency induction heating machine can heat treat workpieces of various specifications and types, and some workpieces need to be quenched not only for the outer circle, but also for the inner hole, which is quite difficult. Today, Zhengzhou Gou's will talk about the sensor that heats the outer circle and the inner hole at the same time.

We encountered a kind of workpiece that requires quenching on both the surface of the outer circle and the surface of the inner hole. The usual method is to quench the outer circle first and then the inner hole. At this time, the outer circle is protected by water spray to prevent tempering. This method is cumbersome to operate. It needs to change the sensor and load and unload it twice, which is time-consuming and labor-intensive, and affects productivity. After many experiments, Zhengzhou Gou's developed a process of heating and quenching the inner hole and outer circle at the same time. The workpiece is a planetary ring gear. After the workpiece is installed, it rises on the general-purpose intermediate frequency induction heating furnace and enters the heating position of the outer circle and inner hole sensors at the same time. The two inductors are respectively connected to two quenching transformers.

Adopt 10kHz, 200kW medium frequency induction heating machine, which supplies two quenching transformers at the same time. The difficulty of this design is that the power distribution on the outer circle and the inner hole inductor must be appropriate, which can be satisfactorily matched by different turns of the inductor and the magnetic conductor. The wall thickness of the above-mentioned workpiece is only 12.7mm. According to this design, the inner and outer circles can be simultaneously scanned and quenched for the thick-walled pin sleeve parts.

Zhengzhou Gou's has been engaged in the induction heating industry for fifteen years, and has done countless inductors. We have a good understanding of the manufacture of inductors. We can make suitable inductors for you according to your workpiece type. If you need to make sensors, you can contact us.
