Presumably, many people are not unfamiliar with medium frequency smelting, and the concept of medium frequency diathermy is relatively vague, because the previous diathermy forging process mostly used coal burning diathermy. Next, let's talk about the induction heating methods of medium frequency diathermy furnace. According to the size of heating blank and different heating specifications, the heating of medium frequency diathermy furnace can be divided into the following heating methods: periodic induction heating, sequential induction heating and continuous induction heating. Different heating methods achieve different effects. Well, don't say much. Let's read the article together.
According to the size of heating blank and different heating specifications, the heating of medium frequency diathermal furnace can be divided into the following heating methods:
1. Periodic induction heating. That is, only one blank is put into the diathermy sensor for heating. After reaching the required heating temperature, the power supply is stopped, the heated blank is discharged from the furnace, and then a cold blank is put into it.
2. Sequential induction heating. That is, multiple blanks are placed in the inductor at the same time. In the process of induction heating, these blanks are pushed from one end of the inductor to the other end according to a certain time beat, that is, every time a cold blank is added from the feed end, a hot blank reaching the heating temperature is produced from the discharge end. When the cold blank is fed, the inductor does not power off.
3. Continuous induction heating. That is, the long blank continuously passes through the inductor, gradually heats to the required temperature in the process of constant speed forward, and continuously discharges from the discharge end, and the inductor does not cut off power.
From the form of medium frequency diathermy furnace, it is mainly divided into horizontal and vertical. The loading and unloading and blank feeding mechanism adopts electric, pneumatic or hydraulic transmission.
