[Introduction] IF induction heat through, because of its high thermal efficiency, uniform heating, the low rate of burning materials and precise control of heating temperature, etc., have been widely used in various types of metal materials processing fields.Due to be able to accurately control the heating temperature, not only to improve the quality of the forging, but also to ensure that post-forging heat treatment effect. Equipment uses prestressedstructure, strength, long life, easy to maintain. Sensors designed, high efficiency, the first pulse-heating methods,the effective elimination of large-diameter heating temperature difference between the heating diameters, which is leading level in domestic. [Our Suggestions] 1.Chooseintermediate frequency heating furnacefor the blank with diameter above Ø15mm 2. Choose mains frequency heating furnace for the blank with diameter above Ø100mm [Technical Parameters] Product Namemains frequency(50 or 60 Hz)intermediate frequencyModelDimension (mm)Rated Power (KW)Productivity(t/h)temperature (oC)transformer capacity (KVA)cooling water(t/h)dimension (mm)frequency(Hz)power (Kw)400kWGTL-1425Ø145x2504000.73500630625 300400 2500100 1500500kWGTL-1960Ø190x6005001.550063010GTL-1760Ø175x6004401.26500GTL-1630Ø160x3004201.15500GTL-1360Ø130x6003801.95007.5600kWGTL-2770Ø270x(300 700)5762.0520800GTL-2770Ø222x(300 700)5612.0520GTL-1770Ø172x7005501.8520800kWGTL-3640Ø360x(250 400)6502.8450100019GTL-3185Ø310x(700 850)7403.0470GTL-2785Ø270x(300 850)8003.05201300kWGTL-32120Ø320x120013005.0520160025700kWGTL-1430Ø145x3007001.79008001520 200400 2500100 1500900kWGTL-2050Ø200x5009343.390019GTL-1850Ø180x5007983.0900GTL-1445Ø145x4507322.79001300kWGTL-3065Ø295x65013005.0900160025
