The intermediate frequency steel shell furnace body is made of high-quality raw materials and good processing technology, which improves the system efficiency, has stable performance and saves energy. Now it is widely used in the smelting of ferrous metals such as stainless steel, carbon steel and alloy steel, as well as non-ferrous metals such as copper and aluminum, as well as in forging, heat treatment (quenching), welding, pipe bending, metal diathermy, rolling and other processing processes. The structure of the furnace body is mainly divided into three parts: furnace shell, yoke and coil. The furnace shell structure is divided into three structures: steel shell, furnace shell and stainless steel aluminum shell: Furnace shell The shell of the small-capacity furnace body is generally made of aluminum alloy or stainless steel, with a reasonable structure, small volume, convenient installation, simple maintenance, and low maintenance cost. The furnace body generally adopts a mechanical tilting furnace device (reducer). The outer shell of the large-capacity intermediate frequency steel shell furnace adopts a steel frame structure, and the furnace body structure is composed of a furnace body fixing frame and a furnace body, and the furnace body fixing frame and the furnace body adopt an integral skeleton structure. The tilting of the furnace body is controlled by the hydraulic system, which is realized by the two hydraulic cylinders on both sides of the furnace body, and the reset of the furnace body is realized by the pressure generated by the self-weight of the furnace body. The height and diameter of the molten iron in the furnace are relatively high. Yoke The furnace body has a built-in profiling yoke, and the shielding of the yoke can reduce magnetic flux leakage, prevent the furnace body from heating, and improve the efficiency. At the same time, the yoke plays the role of supporting and fixing the induction coil, so that the furnace body can achieve high strength and low noise. Coil The coil is the heart of the induction furnace. The induction coil generates a strong magnetic field under the action of the current. This magnetic field causes the metal in the intermediate frequency steel shell furnace to generate eddy current and heat up. The coil is the key to converting electrical energy into heat, so the design of the coil is very important.
