The medium frequency induction diathermy furnace refers to the overall penetration type of metal before thermal deformation or heat treatment. It is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (above 300HZ to 20K HZ). Magnesium brick manufacturers put three-phase power frequency alternating current After rectification, it becomes DC power, and then the DC power is changed into an adjustable intermediate frequency current, and the intermediate frequency alternating current flowing through the capacitor and the induction coil is supplied, and a high-density magnetic line is generated in the induction coil, and the cutting induction coil is filled. The metal material produces a large eddy current in the metal material.
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.
