Medium frequency induction diathermy

The medium frequency diathermy furnace heating device has the advantages of small volume, light weight, high efficiency, excellent thermal processing quality and favorable environment. It is rapidly eliminating coal-fired furnaces, gas furnaces, oil-fired furnaces and ordinary resistance furnaces. Metal heating equipment.

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. 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. The temperature of the energized coil itself is already low, but the surface of the cylinder is heated to redness or even melt. And the speed of this redness and melting can be achieved by adjusting the frequency and current intensity. 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 induction diathermy furnace is widely used in forging heating [for bar, round steel, square steel, steel plate through heat, temperature compensation, blue quenching online heating, local heating, metal material online forging (such as gears, axles) Precision forging of connecting rods, bearings, etc., extrusion, hot rolling, heating before shearing, spray heating, thermal assembly, and overall quenching, annealing, tempering of metal materials. Heat treatment [mainly for shafts (straight shaft, variable diameter shaft, camshaft, crankshaft, gear shaft, etc.); gears; sleeves, rings, discs; machine tool screws; guide rails; planes; ball heads; hardware tools, etc. Surface heat treatment of mechanical (automobile, motorcycle) parts and tempering, annealing, tempering of metal materials, etc.

The medium frequency induction diathermy furnace is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency (300HZ 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. The intermediate frequency alternating current flowing through the capacitor and the induction coil generates a high-density magnetic line in the induction coil, and cuts the metal material contained in the induction coil to generate a large eddy current in the metal material. Since the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself. The average worker can use the medium frequency electric furnace to carry out the continuous work of the forging task ten minutes after going to work. The professional workers do not need to burn the furnace and seal the furnace in advance. . Since the heating method has a high heating rate, the oxidation is extremely small, the oxidation burning loss of the intermediate frequency heating forging is only 0.5%, the oxidation burning loss of the gas furnace heating is 2%, the coal burning furnace reaches 3%, the intermediate frequency heating process material, each Compared with coal burning furnace, tons of forgings can save at least 20-50 kg of steel raw materials. Medium frequency induction heating furnace has fast heating speed, medium frequency furnace production efficiency is high, medium frequency furnace has less oxidative decarburization, medium frequency furnace prolongs mold life, medium frequency furnace has excellent working environment, medium frequency furnace improves worker labor environment and company image, medium frequency furnace has no pollution, medium frequency furnace Low energy consumption, medium frequency furnace melting speed, medium frequency furnace power saving effect, less burning loss, low energy consumption, medium frequency furnace self-mixing function, melting temperature and metal composition uniform, medium frequency furnace electric heating working environment, medium frequency furnace starting performance Well, the empty furnace and the full furnace can reach 100% startup.
