MFS medium frequency heating systems

medium frequency induction heating systems and heating power supplies

Medium frequency induction heating systems (MFS series) are acetized by frequency range 500Hz～10KHz and power100～1500KW，they are mainly used for penetrated  heating, such as rod heating for shaping, melting, fitting and preheat for welding. Due to its wide frequency range, satisfied heating effect is easily achieved by design to considerate all factors such as penetrating desire, heating efficiency, working noise, magnetic stirring force and so on. In MFS medium frequency machines，parallel oscillating structure is used . IGBT module power components and our fourth generation inverting control technologies are applied to ensure high quality and reliability. Fully protection is adopted such as over current protection, water fail protection, over temperature protection, over voltage protection, short circuit protection and phase fail protection.  When working, output current, output voltage , oscillating frequency and output power are all displayed on the operating panel to help in the design of the coil and adjust of the machine. According to different usage, two main structures are used: (1) structure 1 ：MF generator + capacitor + coil This structure is adopted often in many uses, such as rod induction heating machine and melting machine.  This structure is simple, low lost and high efficient in heating. In this structure, usually  3 to 15 meters copper tube is needed to make the coil;  voltage of the coil  is high to 550V, and not isolated to the power supply system, so coil must be insulated properly to ensure the safety of operators. （2）structure 2：MF generator + cap + transformer + coil This structure is also used often, such as melting in vacuum, medium frequency induction hardening machine and so on.   Through the design of transformer ratio,  output current and voltage can be controlled to satisfy different heating desire. In this structure,  coil is safe for operators,  coil tube can exposed directly with out insulation.  Coil is easy to make with only a few turns. Of course, transformer will increase the cost and consumption the machine. Specifications
