What are the medium frequency heating equipment?

The medium frequency electric furnace is an electromagnetic induction heating equipment for heating a metal workpiece, which is widely applied to steel bars, steel pipes, steel bars, deformed steel bars, and the like. How much do you know? If you don’t know, then look down.

The principle of induction heating equipment for metal workpiece is that the relationship between induction heating coil and heated object (metal) is the same as that of primary side and secondary side coil of transformer. The magnetic line produced by the high frequency current of the heating coil is concentrated on the heated object, and the vortex current is generated by the induction of the electromagnetic field, which will be heated by the heated object. At this time, the appropriate AC current frequency, power, heating time, retention time, coil shape and so on can be selected according to the type and shape of steel, so that all kinds of steel can get appropriate quality characteristics. Its thermal efficiency is 95%. Induction heating is to turn three-phase power frequency alternating current into direct current after rectification, and then DC into adjustable intermediate frequency current, to supply intermediate frequency alternating current flowing through capacitance and induction coil, to produce high density magnetic line in induction coil, and to cut metal material in induction coil to produce large swirl in metal material. The workpiece relies on the Joule heat of these currents to reach the expected temperature. If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same, and the harmful gas will not be produced in the heating process of the cylinder, and the strong light will pollute the environment and so on. Because induction heating has the above advantages, it has been widely used in various industries.

Hebei Yuantuo electromechanical induction heating equipment manufacturer believes that the common heating equipment mainly includes resistance furnace, gas furnace and far infrared heating furnace. Resistance furnace is an industrial furnace that uses current to heat the electric heating element or heating medium in the furnace, so as to heat the workpiece or material. Resistance furnaces are used in the mechanical industry for pre-forging heating, metal heat treatment heating, brazing, powder metallurgical sintering, glass ceramic baking and annealing, low-melting metal melting, drying of sand type and paint film.
