Induction heating is widely used for surface quenching of gears, shafts, crankshafts, cams, rolls and other workpieces in order to improve the wear resistance and fatigue breaking resistance of these workpieces. Induction heating surface quenching is adopted for the rear half axle of automobile, and the number of fatigue cycles under design load is about 10 times higher than that with quenching and tempering treatment. Medium frequency induction heating furnace is widely used in:
1. Smelting of non-ferrous metals [it is mainly used for smelting ferrous metal materials such as steel, alloy steel, special steel and cast iron, as well as non-ferrous metal materials such as stainless steel and zinc. It can also be used for smelting, heating and thermal insulation of non-ferrous metals such as copper and aluminum, and can operate in tandem with blast furnace.]
2. Forging heating [used for diathermy of bar, round steel and square steel, temperature supplement, on-line heating of blue quenching blanking, local heating, on-line forging of metal materials (such as precision forging of gears, half shaft couplings and bearings), heating before extrusion, hot rolling and shearing, hot assembly, and overall quenching and tempering, annealing and tempering of metal materials]
3. Heat treatment [mainly for shafts (straight shaft, reducer shaft, camshaft, crankshaft, gear shaft, etc.); Gears; Sleeves, rings and discs; Machine tool lead screw; guide; Plane; Ball joint; Surface heat treatment of various mechanical (automobile, motorcycle) parts such as hardware tools and overall quenching and tempering, annealing and tempering] of metal materials
