induction billet heater 300KW

induction billet heater MFS-300 Main specifications: Maximum input power: 300KW Maximum frequency: 0.5-8KHz Maximum input current: 500A Input voltage: 380VAC three phases, 50 or 60Hz The range of operating voltage: 342-430V Duty cycle: 100% Efficiency: 90% Cooling water: 25-35m3/h Generator weight:350KG Generator size: (L x W x H):920 x 930 x 1950mm Main applications: Hot Forging/forming for large workpiece Surface hardening for large part Preheating of pipe bending Annealing of pipe welding Melting of copper, aluminum and so on Shrink-fit of sleeve of roller Etc. Main characteristics: voltage feedback design and adopt IGBT based LC series resonance circuit IGBT inversion technology ,high energy conversion over 97.5%energy saving 30%up compared with SCR technology. In series resonance circuit, induction coil with high voltage and low current, so energy loss is very low. Soft switch technology applied then switch loss is very low. it can be started up 100% under any condition.100% duty cycle , 24hours continuous working ability at maximum power. less harmonic current and high power factor. Power factor always remaining 0.95 above during machine running.the frequency tracking automatically technology enables power factor to remaining high level throughout heating process. Good reliability, IGBT is a self turn-off transistor that ensures inversion with success and takes protection instantly; IGBT used from infineon company, world-renowned manufacturer.easy to operate and maintain, IGBT MF induction generator is easy to prevent and maintain due to its simple circuit structure. It has perfect protection. Options: a range of heating furnace, customized different type of heating furnace according customer’s requires. infarared sensortemperature controller.CNC or PLC controlled mechanical fixture for hardening application.hydraulic pumpwater cooling systempneumatic rod feeder.customized whole automatic heating system.
