Description

Removable class buggy ladle private cable

Technical field:

The utility model relates to the private cable field, relates in particular to a kind of removable class buggy ladle private cable.

Background technology:

Buggy ladle belongs to the converter auxiliary equipment, be a very crucial equipment, if fault can cause the stagnation of whole operation, cause cable short circuit even meeting breaking out of fire on the trailing cable that drips to buggy ladle owing in the process of converter, there are a large amount of molten steel to spill, have to overhaul or the replacing cable, the such order of classes or grades at school of cable fault of tool statistics takes place three times at least, probably wastes 60 minutes at every turn, thereby cause normal production routine change, make degradation problem under the production efficiency.

Common buggy ladle cable is in operation and is subject to such environmental effects, resistance to elevated temperatures is poor, anti-especially molten steel calcination poor performance, cause cable often to damage, cause normal production routine change, make degradation problem under the production efficiency, not only lose time but also have very big danger when changing cable, produce black smoke endotoxin contamination environment behind the cable fire, had a strong impact on the normal operation of cable, and limited buggy ladle and changed towards heavily loaded high speed direction.

The utility model overcomes the deficiency of above-mentioned prior art, structurally thin requirement, the form of single sheet of insulating barrier abandoning tradition, adopt composite construction, strong assurance the continuity in hot environment, used of cable, for reaching this kind cable tensile property, symmetry adds steel wire in the middle of core, form the 3+3 structure of symmetry, stressed even when making the steel wire tension; Be strict with in selection, insulating material is selected the heat-resisting silicon rubber insulation of potteryization for use, and temperature resistant grade is more than the ordinary silicon rubber-covered far away, and braided wires is selected zinc-coated wire for use, has both increased the flexibility of cable, has increased the ability of the anti-molten steel calcination of cable again; Require highlyer on technology, the material of each operation all satisfies the high flame resistance class requirement, guarantees that cable can operate as normal under hot environment.By setting about from above aspect, can guarantee that the utility model satisfies under the high temperature occasion, move the instructions for use of using and bearing bigger resistance to tension, its temperature resistant grade is higher, and particularly anti-molten steel calcination ability is superior.

The utility model content:

The purpose of this utility model provides a kind of removable class buggy ladle private cable, solved in high temperature mobile tensile occasion the existing buggy ladle cable deadly defect of continuous service for a long time, solved successfully that the not anti-molten steel calcination of buggy ladle cable, cable dilatoryly back and forth in the high-altitude are very easily broken, the cable fixing point is because for a long time stressed problem such as often be short-circuited.

Technical scheme of the present utility model is as follows:

Removable class buggy ladle private cable; comprise several conductors, insulating barrier; described several conductor is enclosed with lapping layer, insulating barrier, protective layer one outward successively; it is characterized in that: the gap of described many conductors outside, twining package tape inboard is provided with many tension finer wires and filler as filling, and described many conductors are enclosed with twining package tape, protective layer two, restrictive coating, thermal insulation layer, armour outward successively.

Described removable class buggy ladle private cable; it is characterized in that: described lapping layer adopts double-deck synthetic mica tape to add the gluing glass fibre belt; described insulating barrier is the heat-resisting silicon rubber of potteryization; described protective layer one adopts the organic synthesis mica tape to add the gluing glass fibre belt; described filler is the high temp glass silk; described protective layer two adopts double-deck gluing glass tape; described restrictive coating adopts the heat-resisting silicon rubber of fire-retardant potteryization; described thermal insulation layer adopts three laminated one-tenth mica tapes to add two layers of gluing glass fibre belt, and described armour adopts the zinc-coated wire braiding.

1, conductor

As more than 750 ℃, conductor also can adopt silver-plated or nickel plating copper wire flexible conductor structure in some superhigh temperature occasion.

2, insulating barrier

Insulating barrier adopts the duplex structure; primary insulation adopts double-deck synthetic mica tape to add high-performance gluing glass fibre belt; novel organosilicon polymer composite-heat-resisting silicon rubber of potteryization is adopted in the middle level insulation; the outer organic synthesis mica tape that adopts adds high-performance gluing glass fibre belt; help keeping the superior isolation performance of this cable; potteryization tensile type silicone rubber insulation layer can continue to use in the high-temperature work environment more than 500 ℃; even also can be in the regular hour in some hyperthermal environments ablatedly change into hard ceramic-like material; form the good isolated protective layer of one deck; the continuation that stops high temperature is ablated; and the ablation time is long more; temperature is high more; hard effect is obvious more, has well prolonged the useful life of cable.

Mica tape is peripheral, and glass fibre belt has been strengthened its heat-resisting quantity and fire resistance, has well protected mica tape again with wrapped protection mica of gluing glass fibre belt and insulating barrier, makes mica be difficult for being galled.

3, stranding is filled wrapped

Stranding adopts the high-temperature glass fibre silk to fill, and adds three finer wires in the middle of three insulated wire cores, forms the 3+3 symmetrical structure, makes steel wire stressed evenly, survivable insulation or sheath.Twining package tape adopts composite structure, adopts two-layer low smoke and zero halogen band overlapping wrapped earlier, adopts two-layer gluing glass fibre belt overlapping wrapped again, has promptly guaranteed the whole heat-resistant fireproof ability of cable, makes cable not produce black smoke toxin environmentally safe again when burning.
