Steel pipe hot expanding middle frequency induction heating furnace
Specification:
The induction heating furnace is widely used for the preheating for the steel pipe hot expanding. It takes advantage of the electromagnetic induction principle for heating to achieve quick heating.
The complete set of inductin heating furnace is made of middle frequency power supply, capacitance transformer cabinet, induction heating coil, water cooling connecting cable, supporting lining, furnace body fixture.
Description:
The whole system adopts full digital control which can realize power factor calibration, constant power control, temperature control, frequency tracking, zero power start-up, real-time monitor on over-current and over-voltage faults, alarm display etc.
Complete and reliable protection system on over current, over voltage, low voltage etc.
The induction heating furnace adopts unique zero voltage, sweep frequency, soft start-up mode, users can leisurely select one-time start-up or automatic repeatable start-up mode.
The central control panel adopts single-panel structure, highly integrated, 3 phases synchronous, rectification trigger and control, inversion trigger and control, the rectification pulse transformer unit is mounted on a central control panel which is of high interchangeability and convenient for user maintenance and change.
The equipment has a complete and reliable automatic adjustment system made up of current, voltage, impedance and inverter leading trigger angle adjustments. The current and voltage double circles automatically achieve constant power adjustment, the impedance adjustment can make the power supply be the optimum state during the whole smelting process.
The lining can be categorized into the following types: white corundum, stainless steel and integral sintered, which can be selected by users themselves.
Competitive advantage:
High speed of heating.
The induction power supply can be used for different sizes of steel pipes.
Less oxidation and decarbonization.
Less energy consumption.
No pollution to environment.
High degree of automation.
The equipment can achieve fully unmanned operation.
Homogeneous heating.
Quick IGBT driver which can improve the shapes of resonant waves, reduce the time of dead zone and decrease the loss of switch as well as increase the stability of the high frequency tracking converter.
Engineers are available abroad for installation, debugging as well as training.
