Abstract
This invention relates to an inductive smelting furnace with a compound housing of an outer shell of steel and an inner shell of aluminium fixed together. Said outer shell and inner shell are all formed by two halves of left and right butt-through fastened by screw bolts with insulation cover and insulation washer at the joint part of the screw bolt and the outer shell and the inner shell. There is a magnetic shield plate formed by two unconnected halves on the internal surface of the inner shell bottom, and in the cavity formed by the inductive coil and the inner shell there are several support rods radial-arranged from upper to down, one end of which is insulation block fastened with the bakelite axially and uniformly arranged around the inductive coil, and the other end of which is a steel piece fastened with the inner shell.
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 bleed-out 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, shell and inner casing are by a left side, right two halves are by being with the bolt of insulating sheath, and the bolt two ends and in, shell merging place adds felt pad respectively to wearing fastening forming, inner surface device at 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, the direct-axis all around that places the induction coil in the housing is to the bakelite posts that are evenly equipped with several fixing every circle coils, 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 inner casing port annular tile is arranged, in the cavity of induction coil and inner casing formation, 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 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.
Description of drawings
Fig. 1 is the longitudinal sectional drawing of inducing smelting furnace with composite shell;
Fig. 2 is the furnace shell A-A view of Fig. 1;
Fig. 3 is the magnetic shield panel schematic diagram.
The specific embodiment
With reference to Fig. 1, the inducing smelting furnace with composite shell of invention has stainless steel casing 1-1 and the aluminium inner casing 1-2 that is fixed in one, shell and inner casing are by the bolt 3 of left and right two halves by being with insulating sheath, and add 4 pairs of felt pads respectively in bolt two ends and merging place of inside and outside shell and wear fastening forming, can avoid forming circulation.Usually, be to save material and further reduce dispersion loss, can be in the bottom of stainless steel casing, be welded with several and stretch to the center along circumferential (see figure 2) is uniform, be used to support and fixing inner casing
Type carriage 5, and make inner shell bottom ringwise.Inner surface device at inner shell bottom has disjunct annular magnetic shielding copper coin 6, can adopt two disjunct annular slabs that match with the inner shell bottom shape as shown in Figure 3.On the magnetic screen copper coin, be provided with water-cooled copper 7.Induction coil 2 places in the housing, direct-axis is to being evenly equipped with several bakelite posts 8 around it, the every circle coil and the bakelite post of induction coil are fixed, in the illustrated example, the lower end of induction coil utilizes the bakelite post to be positioned to be located in the groove of refractory brick 9 of magnetic screen copper coin 6 tops, and fix with leg fixture 12 and furnace bottom, between the upper end of coil and the inner casing port annular tile 10 is arranged, in the cavity of induction coil and inner casing formation, the support bar 11 that some radial arrangement are arranged from top to bottom, an end of support bar is collets, and is fastening with bakelite post 8, the other end is a stainless steel, and is fastening with inner casing.
