Intermediate frequency induction hardening equipment has many advantages. Intermediate frequency electromagnetic induction heating equipment, induction hardening equipment, quenching and tempering furnace, forging diathermy equipment is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (300HZ to 1000HZ). The 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 to generate high-density magnetic lines of force in the induction coil and cut the induction coil The metal material contained in the metal material produces a large eddy current in the metal material.
The principle of intermediate frequency induction heating equipment and intermediate frequency induction hardening furnace is electromagnetic induction, and its heat is generated by itself in the metal workpiece. Ordinary workers can use electric induction heating equipment, intermediate frequency induction hardening equipment, and quenching and tempering furnace to perform induction within a few minutes after work. The normal operation of the heating equipment can be started by turning on the power supply. Due to the fast heating rate of this heating method, there is very little oxidation. The medium-frequency electric induction heating equipment has little oxidation and decarburization, and the loss is only 0.5%. The oxidation burning loss of gas furnace heating is 2%, and the coal-fired furnace reaches 3%. Heating equipment and induction hardening process save raw materials, and each ton of forgings saves at least 20-50 kilograms of steel raw materials compared with coal-fired furnaces. The intermediate frequency induction heating furnace has fast heating speed, high production efficiency, less oxidation and decarburization of induction heating equipment, long service life of induction hardening equipment, superior working environment, and improving the labor environment of workers and the company’s image.
