According to the frequency of the alternating current level can be divided into ultra-high frequency induction heating heat treatment, high-frequency, super audio, frequency, frequency 5 categories. ① ultra-high frequency induction heating heat treatment used in the current frequency up to 27 MHz frequency machine accessories wholesale, very thin layer of high-frequency heating machine parts prices, only about 0.15 mm, can be used for surface hardening thin circular saws and other complex shape of the workpiece. ② high-frequency induction heating frequency of the current heat treatment is usually used 200 to 300 kHz, the heating layer depth of 0.5 to 2 mm high frequency machine parts, can be used for gear, cylinder liners, cams, shafts and other parts of surface hardening. ③ Super Audio induction heating current frequency used in heat treatment is generally 20 to 30 kHz, for small module gear with Super Audio induction heating current, heat distribution layer generally along the tooth profile, pure fire after using better performance. ④ induction heating heat treatment used in the current frequency is generally 2.5 to 10 kHz, the heating layer depth of 2 to 8 mm high-frequency machine parts manufacturers, and more for large modulus gear, larger diameter shafts and other parts of cold roll surface hardening. ⑤ frequency induction heating heat treatment used in the current frequency of 50 to 60 Hz, the heating layer depth of 10 to 15 mm, can be used for surface hardening of large workpieces. High frequency induction heating machine is mainly used to adapt to industry-wide industry are: high frequency induction welding, high frequency induction heat treatment, high frequency induction metal smelting. Such as: carbide saw blades, diamond cutting tools, drilling, turning, planing, milling cutters, reamers and other cutting welding; heat standard parts, bolts, power tools, hardware tools, hand tools; pliers, wrenches, screwdrivers tools, hammers, axes, auto parts, crankshaft, connecting rod, piston pin, crank pin, sprocket, camshaft, valves, all kinds of rocker, rocker shaft; transmission of various gears, spline shaft, mass support axle, a variety of small axes, various fork and other high-frequency quenching treatment.
