It is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency (300HZ or more to 1000HZ), converts the three-phase power frequency alternating current into a direct current, and then converts the direct current into an adjustable intermediate frequency current, which is supplied by the capacitor and the induction. The intermediate frequency alternating current flowing in the coil generates high-density magnetic lines of force in the induction coil, and cuts the metal material contained in the induction coil, and the intermediate frequency furnace ramming material generates a large eddy current in the metal material.
The medium frequency induction furnace (hereinafter referred to as the intermediate frequency furnace) operates at a frequency between 50 and 10 Hz and is widely used for the melting of non-ferrous metals and ferrous metals. Compared with other casting equipment, the medium frequency induction furnace has the advantages of high thermal efficiency, short melting time, less burning of alloying elements, wide melting material, less environmental pollution, and control of the temperature and composition of the molten metal.
This eddy current also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. The three-phase bridge type full-controlled rectifier circuit is used to rectify the alternating current into direct current. For example, a metal cylinder is placed in an induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil, and the temperature of the energized coil itself is already very high. Low, but the surface of the cylinder is heated to redness or even melt, and the speed of redness and melting can be achieved by adjusting the frequency and current. If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same. The cylinder is heated and melted without generating harmful gases or strong light to pollute the environment. Medium frequency furnace is widely used in the melting of non-ferrous metals
It is mainly used in the melting of ferrous metals such as molten steel, alloy steel, special steel and cast iron, as well as non-ferrous materials such as stainless steel and zinc. It can also be used for the melting and heating of copper, aluminum and other non-ferrous metals, heat preservation, and double with blast furnace. Run together. Forging heating is used for bar, round steel, square steel, steel plate for heat transfer, temperature compensation, blue quenching, on-line heating, local heating, metal material forging (such as gears, semi-shaft connecting rods, bearings, etc.) Extrusion, hot rolling, heating before shearing, spray heating, thermal assembly, and overall quenching, annealing, tempering of metal materials. Heat treatment and quenching production line [To supply shafts (straight shaft, variable diameter shaft, camshaft, crankshaft, gear shaft, etc.); gears; sleeves, rings, discs; machine tool screws; guide rails; plane; ball head; Surface heat treatment of various mechanical (automobile, motorcycle) parts and overall quenching, annealing, tempering of metal materials.
The intermediate frequency furnace is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency (300HZ or more to 1000HZ), converts the three-phase power frequency alternating current into a direct current, and then converts the direct current into an adjustable intermediate frequency current, and supplies the capacitor. And the intermediate frequency alternating current flowing through the induction coil generates high-density magnetic lines in the induction coil, and cuts the metal material contained in the induction coil to generate a large eddy current in the metal material. The metal is heated by the principle of electromagnetic induction.
