The steel is heat treated using medium frequency induction heating equipment, which can effectively save energy by shortening the heat treatment cycle of the steel.

Many people say that steel is heat treated using medium-frequency induction heating equipment, which can greatly reduce the energy consumption of steel compared with other heat treatments. Although many people say this, some still don't believe it. Today, the editor will use real data to prove to everyone whether this statement is correct.

The important difference between the induction heating rapid heat treatment process and the traditional heat treatment process is that the former uses rapid temperature rise to increase the processing temperature to shorten the holding time, accelerate the phase change process, and achieve the same heat treatment effect. Production practice has proved that the measure of exchanging temperature for holding time is effective for normalizing, quenching, solid solution, tempering and annealing of most steels. In this way, the use of medium frequency heating equipment for induction heating rapid heat treatment process can significantly shorten the production cycle of the traditional heat treatment process and save a lot of energy. Table 1 gives the heat treatment process of low alloy steel with different heating methods. It can be seen from the heat treatment process in the table: the induction heating heat treatment temperature is 50-100°C higher than the traditional process, and the longest holding time for induction heating is 2 minutes, while traditional heating is 40-120 minutes. Trading temperature for holding time shortens the heat treatment production cycle , and save energy. The specific energy-saving data of different heat treatments are detailed in Table 2.

From the above description, we can see that steel is heat treated with medium frequency induction heating equipment. Energy can be effectively saved by shortening the heat treatment cycle of steel. Therefore, we should strongly advocate it.
