Converting Unit 5 and Converting Unit 6 series resonant inverter.
Embodiment 2: as shown in Figure 1, Converting Unit 5 and Converting Unit 6 parallel inverter, Converting Unit 5 and Converting Unit 6 are connected to rectifying part.All the other contents are with embodiment 1.
Embodiment 3: as shown in figures 1 and 3, high energy efficiency induction heating apparatus, comprise furnace shell 1, furnace bottom 3 and furnace lining 2, upwards induction coil 11 and induction coil 12 is provided with successively along furnace lining 2 outer wall from furnace bottom 3, also comprise the supply unit possessing and switch power supply mode, the power supply that supply unit uses is intermediate frequency power supply, supply unit comprises rectifying part 10, rectifying part 10 is electrically connected with Converting Unit 9, two ports of Converting Unit 9 are electrically connected by water-cooled cable 4 with induction coil 11 and induction coil 12 respectively and each water-cooled cable 4 is provided with change-over switch 8, induction coil 11 and induction coil 12 are arranged in parallel.
In addition, in above-described embodiment, the quantity of induction coil can also be other quantity such as three or four.
Use procedure:
At the fusing initial stage, first to the independent high-power power supply of induction coil 11 near furnace bottom 3, under the induced field of high power density, bottom metal furnace charge rises rapidly molten, plays molten speed faster than traditional melting scheme more than 3 times;
Bottom furnace charge forms fusion rapidly, can absorb more magnetic field energy, produce larger eddy current, make bottom metal furnace charge rapid melting, form a high temperature molten bath in bottom after rising and melting, and top furnace charge, under gravity or manpower effect, enters molten bath and continues fusing;
After metallic solution liquid level is higher than induction coil 11, stop powering to induction coil 11, or reduce the power delivery of induction coil 11, make it be in keeping warm mode.This process can ensure that bottom metal liquid temp is unlikely too high, reduces furnace lining 2 and corrodes.On the one hand, the reduction of bottom power, can weaken or eliminate magnetic field force washing away furnace bottom skirt angle, avoids the formation of elephant pin effect.Great role is had to raising furnace lining 2 life-span.Furnace lining 2 life-span can be made to improve 1-3 doubly;
Reduce or stop while induction coil 11 power supply, high-power, high power density provides energy to induction coil 12, makes induction coil 12 enter the efficient fusion stage;
The like, supply unit upwards switches the output power to induction coil successively, until fusing terminates.Whole operating process will adjust charging rate in time, control power density will avoid the formation of locally warm area affects furnace lining 2 life-span.There is not the overtemperature stage in whole operating process, makes furnace lining 2 evenly ablation, extend furnace lining 2 life-span.
After end to be melted, distribute power and power to all induction coils, homogenising is made it to the overall temperature raising of molten metal and adjusting component.
