The utility model adopts the special structures that an oxide film aluminium beltwinding is adopted, corrosion prevention and waterproofing protective layer of resin, etc. is coated on the outer surface of the winding, aluminium belts are adopted to directly lead out the transition joint of copper and aluminium, etc. The utility model has the advantages of low cost, light weight, small size, high temperature resistance, corrosion resistance, long service life, high work efficiency, etc. The utility model can widely used on magnetic stirrer devices on continuous casting machines in metallurgy industry.
Description
The utility model relates to a kind of when metal melting casts continuously, uses the auxiliary device that magnetic effect is handled metal in casting mold.
The winding of magnetic stirrer generally adopts the copper strap wire coiling of handling through insulative water-proof to form at present.This copper strap wire winding is owing to insulating layer thickness, thereby volume is big, activity coefficient is low after the coiling (being about 0.5-0.6).Simultaneously,,,, be stranded this and can cause within a short period of time insulating barrier aging, the insulation quality is descended because of there is hot spots in the big inside of winding temperature gradient though outer surface temperature under cooling water flow impacts is lower because the insulating layer thickness conductivity of heat is relatively poor.Because the copper strap wire winding needs sandwich wound,, so just cause the easy short circuit of turn-to-turn of winding core that winding is burnt again so voltage between layers is higher.
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art and a kind of Oxidation film aluminium belt coil electromagnetic stirrer is provided.
The purpose of this utility model can realize by following structure:
Oxidation film aluminium belt coil electromagnetic stirrer.Structures such as having comprised housing, iron core, magnetic pole, magnetic pole winding and cooling water circulation and powered terminals.Special feature of the present utility model be exactly magnetic pole winding internal structure be that aluminium strip one circle one deck is entwined, it is the Al that 8 to 12 microns anodic oxidations form that the aluminium strip surface has a layer thickness
2O
3Oxide-film, Wrapping formed magnetic pole winding table mask have oxide-film strong adhesion, the good heat resistance (Al of the anticorrosion fish tail and waterproof layer of resin, this oxide-film aluminium strip magnetic pole winding
2O
3Fusing point be 2050 ℃), have good insulation performance (oxide-film does not puncture, do not damage) below power frequency 400V, the activity coefficient of winding can reach 0.95.Because turn-to-turn is tight, good integrity, whole winding temperature is evenly distributed and eliminates hot spots and the low winding reliable operation of voltage between layers.Special feature of the present utility model also is dip-coating silicon organic insulation lacquer in the magnetic pole winding technique, makes winding become firm integral body with further raising turn-to-turn insulation intensity through toasting drying, improves heat transfer property.Descend the insulation putty that evenly fills in the both ends of the surface turn-to-turn slit by epoxy resin and silica flour furnishing thereon after the winding baking, with the turn-to-turn insulation intensity of further enhancing end and improve water resistance.Then, use parallel glass fiber not have three layers of the tight take-up straps of latitude epoxy adhesive tape at magnetic pole winding and leading-out terminal surface.In vacuum Rotary drying stove, be cured.Brush match fluorine dragon (SIOCFLON) coating protection layer on the magnetic pole winding surface that is cured with good waterproof, antiseptic property.Magnetic pole winding al zone thickness of the present utility model is the 0.3-1.0 millimeter, and width is the 30-100 millimeter.Magnetic pole winding leading-out terminal structure is that aluminium strip is directly drawn, and cuts the fillet that is cut into many certain widths with drawing aluminium strip, behind folding and forming, and crimping copper-aluminium transition joint.Thereby avoided copper aluminium directly to connect caused couple corrosion effectively to improve the joint life-span.
The utility model compared with prior art improves one to three times service life, thermal losses is low, can be in hot operate as normal down, its operating efficiency can improve 5% to 10%, realize simultaneously can saving more valuable copper raw material and significantly reducing material cost for copper production agitator winding, simplify technology and the about two/first-class advantage of weight reduction with aluminium
