Abstract
The present invention relates to an induction smelting furnace with a composite shell body. The shell body is provided with a steel outer shell and an aluminium inner shell which are fixed into a whole. The outer shell and the inner shell are respectively formed in the way that a left half and a right half are butt through and fastened by a screw bolt sheathed with an insulating sheath, and an insulating pad is respectively added at the merging points of both ends of the screw bolt, the inner shell and the outer shell. The inner surface of the bottom of the inner shell is provided with a magnetic shield panel formed by two non conterminous halves; in a hollow chamber formed by an induction coil arranged in the shell body and the inner shell, a plurality of support bars arranged in the radial direction are arranged from top to bottom. One end of each support bar is provided with an insulation block fastened with bakelite poles which are uniformly distributed along the axial direction around the induction coil, and the other end is provided with a rigid component fastened with the inner shell. Due to the fact that the aluminium inner shell is used and the magnetic shield panel is covered on the bottom of the aluminium inner shell, the induction smelting furnace can shield magnetic leakage around the induction coil and effectively reduces the temperature rise of a furnace body. Due to the fact that space is formed between the aluminum inner shell and the induction coil, the reliable insulation distance and the safe running are ensured, and the sufficient maintenance space is provided, which is in favor of maintenance.
Description
Technical field
The present invention relates to induction melting furnace.
Background technology
Induction melting furnace is in Metal Melting and the existing application very widely of casting industry.It is to utilize when passing to alternating current in the coil, can produce alternating magnetic field in coil, makes the metal material that places coil be heated to fusing because of electromagnetic induction produces eddy current and heating.The present induction melting furnace that uses, its housing is to be welded with ordinary carbon steel, device has induction coil in the housing, consider carbon steel easily heating in leakage field, then outside induction coil, surrounded the magnetic conductor that a circle is made of silicon steel sheet, between magnetic conductor and induction coil, be lined with insulating barrier, for preventing that both from producing relative displacement, this insulating barrier is very thin, only several millimeters of general thickness, the induction melting furnace of this structure is though mechanical strength is fine, but because induction coil is surrounded by magnetic conductor, insulating barrier therebetween is very thin, and is impaired even a small amount of leakage field also can cause insulating, and checks with maintenance also comparatively difficult, even can cause the pernicious stove of wearing, cause induction coil and magnetic conductor to be fused into one and scrap by molten steel.
Summary of the invention
The purpose of this invention is to provide a kind of existing sufficient mechanical strength and dielectric strength, maintain easily maintenance again, can guarantee the inducing smelting furnace with composite shell of safety, reliability service.
The inducing smelting furnace with composite shell of invention, it is two-layer that its housing has the outer steel shell and the aluminium inner casing that are fixed in one, outer steel shell and aluminium inner casing are by a left side, right two halves constitute, and by being with the bolt of insulating sheath, and at bolt two ends and aluminium inner casing, outer steel shell merging place adds felt pad respectively to wearing fastening forming, inner surface device at the aluminium inner shell bottom has the magnetic shield panel that is made of disjunct two halves, device has water cooling tube on the magnetic shield panel, place induction coil in the housing around along circumferentially be evenly equipped with several along housing shaft to the bakelite post of fixing every circle coil, the lower end of induction coil is positioned to be located on the refractory brick of magnetic shield panel top, between the upper end of coil and the aluminium inner casing port annular tile is arranged, in the cavity of induction coil and the formation of aluminium inner casing, the support bar that some radial arrangement are arranged from top to bottom, one end of support bar is collets, fastening with the bakelite post, the other end is the rigidity part, and is fastening with the aluminium inner casing.
Inducing smelting furnace with composite shell of the present invention; owing to adopt the aluminium inner casing and cover magnetic shield panel at the aluminium inner shell bottom; can shield induction coil leakage field on every side; avoid leakage field to cause that other metal parts beyond the aluminum hull generates heat; the heating of avoiding aluminum hull bottom and box hat bottom to cause because of induction; effectively reduce the body of heater temperature rise; guarantee mechanical strength and weight capacity; owing to have the space between aluminium inner casing and induction coil; not only guaranteed reliable insulation distance; guarantee safe operation, and the sufficient space of safeguarding is provided, be convenient to safeguard.
