Intermediate frequency induction heating can not heat non-magnetic materials such as copper, aluminum, austenitic stainless steel, and can not be used to heat workpieces made of insulating materials, because the intermediate frequency induction heating furnace is heated by electromagnetic induction, the insulating material does not have Therefore, the impedance cannot be heated, that is, the intermediate frequency induction heating furnace can only heat metal objects.
The principle of intermediate frequency induction heating relies on induction heating to generate eddy currents. It is a physical phenomenon that the heat generated by closed currents melts metal materials. Characteristics of intermediate frequency induction heating:
1.Complete equipment protectionThe whole machine is equipped with water temperature, water pressure, phase loss, over-voltage, over-current, pressure / current limit, over-current, constant current and buffered startup, so that the equipment starts smoothly, the protection is reliable and rapid, and the operation is stable ;
2, fast heating speed, low oxidation and decarburization. Because the principle of the intermediate frequency diathermy furnace heating is electromagnetic induction, the heat is generated by the workpiece itself. This heating method has fast heating speed, very little oxidation, high heating efficiency, good process repeatability, and metal. The surface is only slightly discolored, and slight polishing can restore the surface to a glossy surface, thereby effectively obtaining consistent and consistent material properties;
3. High degree of automation can realize fully automatic unmanned operation and improve labor productivity;
4. Low energy consumption, high pollution-free heating efficiency Compared with other heating methods, it can effectively reduce energy consumption, high labor productivity, no pollution, and equipment meets environmental protection requirements;
5, high temperature control accuracy, uniform heating to ensure that the temperature difference of the heating core is small, the temperature can be accurately controlled through the temperature control system to ensure product repeat accuracy;
6. The replacement of the furnace body of the intermediate frequency diathermy furnace is simple and easy. According to the size of the workpiece, different types of induction furnace bodies are required.
