Melting furnace using 200 ~ 2500Hz medium-frequency power supply to conduct induction heating, the power range of 20 ~ 2500Kw, while according to its characteristics can also be called as intermediate frequency furnace. Mainly used for precious metals such as gold, platinum, silver, copper, iron, stainless steel, aluminum alloy, aluminum and other metals smelting and for raising temperature, which is ideal equipment for university laboratory, research institutes, jewelry processing. Power using advanced IGBT parts, which is more integrated miniaturized, the effective output power can reach more than 90%, has feature of energy saving, more 60% than traditional thyristor medium frequency furnace.
Melting furnace advantages:
1, Melting furnaces with small volume, light weight, high efficiency, low power consumption;
2, Temperature is low around the furnace, less dust, good working environment;
3, Operation process is simple, and reliable melting;
4, Heating temperature uniform, less burning ratio, uniform metal components;
5, Good quality casting parts, melting temperature raising fast, oven temperature easy to control, and high production efficiency;
6, High utilization ratio, easy to replace varieties;
7, According to its characteristics in the industry, could be called as industrial furnace, electric furnace, high-frequency furnace, small stove, energy-saving stoves etc..
Melting furnace structure introduction:
The entire melting furnace include: medium frequency power supply cabinet, compensation capacitor, furnace body(two) and water-cooled cables, reducer. Furnace body composed by furnace shell, induction coil, lining, tilting furnace gearbox four parts, while furnace shell is made of non-magnetic material, the induction coil is made by rectangular hollow tubular body into a spiral circle shape, when melting, inside the tube cooling by water through. Coil leads out copper bar to connect with cable, lining close to induction coil, made of quartz sand pushing and sintering, furnace body tilting by direct turning of tilting gearbox. Tilting furnace gearbox is secondary turbo speed gearbox system, with good self-locking performance, smooth rotation, and reliable emergency power off when furnace knock off, to avoid danger. Can conduct selection through 2 furnace body tilting furnace gearbox motor by means of selection switch furnace, with 4 core rubber wire switch box allows the operator to stand in a suitable position for tilting the furnace, and the reset through jog control.
At present, more than 3 tons melting furnace generally do not use this kind of structure. The tilting mainly adopts hydraulic, induction coil has several external uniform curved magnet yoke to prevent magnetic flux leakage. With this method, the furnace shell no need to use non-magnetic material, so the outside oven shell is not hot. By using of hydraulic tilting furnace, the tilting process is gentle and safe.
