Principle and application of high frequency heater
From: Dongguan brothers high frequency Machinery Co., Ltd. Post date: 2017-07-06


High frequency heating machine is the fastest heating speed and efficiency for metal materials, and it is a kind of low consumption, energy saving and environmental protection induction heating equipment. In the daily production, this kind of high frequency machine has a wide range of applications.
High frequency heating machine, also called high-frequency heating machine, high-frequency induction heating equipment, high-frequency induction heating device, high-frequency power supply, high-frequency electric furnace, high-frequency heating power supply.
Main working principle:
Large currents of high frequency flow are wound around a loop or other shapes of heating coils. Within the coil produces strong magnetic polarity beam transient changes, the metal is being heated in the coil, the magnetic beam will be through the whole heated object, being inside and the heating current of the heating object in the opposite direction, it will produce large eddy current corresponding to the. Because there is a resistance in the heated object, a lot of Joule heat is produced, so that the temperature of the object itself rises rapidly, and the heating of all the metal materials is achieved.
Use of high frequency heater:
First, hot forming: local forging, whole forging, hot rolling, hot upsetting;
Two, heat treatment: quenching, tempering, annealing, partial or whole heating of various metals;
Three, metal smelting: gold, silver, copper, iron, aluminum and other metal (vacuum) smelting, casting molding and evaporation coating;
Four, metal welding: all kinds of metal products brazing, all kinds of cutting tools, blades, saw teeth, sawtooth welding, steel pipe, copper pipe welding, welding of dissimilar metals;
Five. Other applications of high frequency heater: semiconductor single crystal growth, thermal fit, bottle sealing, toothpaste sealing, powder coating and metal implantation.
