The structure of the medium frequency melting furnace

Medium frequency melting furnace furnace shell structure is divided into two kinds of aluminum and steel shell structure: small capacity furnace shell generally adopt aluminum alloy material, reasonable structure small volume, convenient installation, simple maintenance, low maintenance cost. Large capacity of intermediate frequency furnace shell adopts steel structure, furnace body structure is composed of the fixed frame of blast furnace and ontology, furnace fixed frame and the furnace USES the integrity of the skeleton structure. Furnace body is rotated by a hydraulic system control, depend on either side of the furnace to achieve two hydraulic cylinder jacking, and furnace is reset by the pressure of the furnace body weight of produce.
Furnace iron liquid height and diameter is quite high. This reference foreign advanced type furnace, furnace is set on the basis of computer analysis, slim than increase, improve natural power factor, power efficiency was improved. Furnace built-in copying yoke, magnetic yoke block can reduce the magnetic flux leakage, prevent furnace heating, improve efficiency. At the same time as supporting effect, induction coil, fixed yoke furnace to achieve high strength and low noise. Yoke is to use cold rolled silicon steel sheet, stainless steel plate produced by crescent-shaped yoke, the combination of core and coil surface for circular arc surface, pressure JinChu is a surface rather than a line in the past, the structure of the compaction effect is good, less magnetic flux leakage. For the silicon steel sheet pile, instead of a cast, a splint dedicated to tighten, without special wear heart screw tightening, this structure can make full use of the permeability of silicon steel sheet area, reduce the probability of local heating.
