What are the advantages of intermediate frequency induction heating furnace in heating and forging?

中間周波数 誘導加熱炉 is a power supply device that converts 50HZ AC power into intermediate frequency (from 300HZ to 1000HZ). Since the principle of intermediate frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. Ordinary workers use an intermediate frequency electric furnace after going to work. The continuous work of the forging task can be carried out in ten minutes, without the need for professional furnace firing workers to perform furnace firing and sealing work in advance. Due to the rapid heating rate of this heating method, there is very little oxidation. The oxidation burning loss of intermediate frequency heating forgings is only 0.5%, the oxidation burning loss of gas furnace heating is 2%, and that of coal-fired furnaces is 3%. The intermediate frequency heating process saves materials. Compared with coal-fired furnaces, a ton of forgings can save at least 20-50 kilograms of steel raw materials.

The intermediate frequency induction heating furnace has its own unique five advantages in heating and forging:

First, the melting and heating speed of the intermediate frequency induction heating furnace is fast, the furnace temperature is easy to control, and the production efficiency is high.

Second, the operation process of the intermediate frequency induction heating furnace is convenient, easy to learn, and easy to control.

Third, the temperature around the furnace of the intermediate frequency induction heating furnace is low, there is less smoke and dust, and the working environment is good, which is in line with the contemporary concept of energy saving and environmental protection.

Fourth, the intermediate frequency induction heating furnace has high melting efficiency, good energy-saving and power-saving effects, compact structure and strong overload capacity.

Fifth, the furnace utilization rate of the intermediate frequency induction heating furnace is relatively high, and it is very convenient to replace the furnace body.

The working principle of the intermediate frequency induction heating furnace is: the three-phase power frequency alternating current is rectified into direct current, and then the direct current is transformed into an adjustable intermediate frequency current, and the intermediate frequency alternating current flowing through the capacitor and the induction coil is supplied. High-density magnetic lines of force are generated in the ring, and the metal material contained in the induction ring is cut, and a large eddy current is generated in the metal material. At present, the intermediate frequency induction heating furnace is mainly used in: welding equipment; heat treatment; diathermy forming equipment and other fields.
