Along with developing rapidly of domestic and international material industry, the demand of smelting equipment high-end for large-tonnage is the strongest.Therefore, large-scale electroslag refining furnace arises at the historic moment, and country advocates energy-conservation environmental protection industry energetically at present, so big by traditional design and manufacturing technology difficulty, cost is high.
1, domestic traditional electroslag furnace equipment is single column support arm type, double column rotating arm formula double electroslag furnace, support arm clamp holder clamping dummy electrode and metal electrode, controls actuating device turning T-type screw mandrel and drives roller cantilever to move up and down melting.
2, the transformator of existing domestic electroslag furnace or external import electroslag furnace is conductively connected to the short net of burner, all uses water-cooled cable structure.And the conductive site that much needs on body of heater to be flexible coupling all have employed water-cooled cable structure.As electroslag furnace technological design needs the big electric current by 18000A ~ 45000A, therefore water-cooled cable needs the biggest conductive section, the water-cooled cable so manufactured is thick, stiff, the angle of electroslag furnace equipment multiple-station rotation and the displacement of movement cannot be met, and water-cooled cable is vulnerable to bending and suppresses strength, cause the inside current are not smooth or booster, thus affect electric conductivity, even can lead to even more serious consequence.And heavy in section water-cooled cable manufacture difficulty is big, production cost is high, installs the most inconvenient with regular maintenance.And water-cooled cable is used as the conduction that is flexible coupling in many places on body of heater, so water-cooled cable needs bigger installing space installing when, so short net effectively can not accomplish coaxial or parallel wiring, therefore improve the power consumption of steel per ton and increase production cost.
Summary of the invention
What the present invention proposed is multistation coaxial electrical slag hearth short-net device, and its purpose aims to solve the problem that water-cooled cable limits the body of heater anglec of rotation and the problem of mobile displacement, reduces short net pressure drop and power consumption, reduces production cost and equipment operating cost.
1, the technical solution of the present invention: multistation coaxial electrical slag hearth short-net device, its structure is: include main station, secondary station, the most main station conductive structure is by a phase of transformator, the first main copper bar of conduction, A first conducts electricity and divides a copper bar, A the first contact tube, A the first copper sheet is flexible coupling, A bottom water case, A consutrode, A auxiliary electrode, conductive material bar, big electric current coaxial sliding conduction current collecting equipment, second copper sheet is flexible coupling, body of heater conducting copper, 3rd copper sheet is flexible coupling, upper guide electric contact, A lower guide electric contact, A the second contact tube, A second conducts electricity and divides a copper bar, the second x phase conducting electricity main copper bar and transformator is connected in sequence；
Secondary station conductive structure is by a phase of transformator, the first main copper bar of conduction, 3rd conducting copper, B first conducts electricity and divides a copper bar, B the first contact tube, B the first copper sheet is flexible coupling, B bottom water case, B consutrode, B auxiliary electrode, conductive material bar, big electric current coaxial sliding conduction current collecting equipment, second copper sheet is flexible coupling, body of heater conducting copper, 3rd copper sheet is flexible coupling, upper guide electric contact, B lower guide electric contact, B the second contact tube, 2nd B conduction point copper bar, 4th conducting copper, the second x phase conducting electricity main copper bar and transformator is connected in sequence.
Advantages of the present invention: 1) body of heater rotates and movement is not pind down by water-cooled cable, can move freely by design needs completely；2) reduce the pressure drop of overall short net system, reduce the power consumption of steel per ton, thus reduce production cost；3) manufacturing cost of equipment is reduced；4) water-cooled cable belongs to wearing detail, after 1 ~ 2 year validity period, all can be replaced, and each maintenance downtime is long, costly.After water-cooled cable is cancelled, equipment uses this expense that unit is saved, and improves the productivity ratio of equipment；5) need not suspension water-cooling cable and cooling water pipe, therefore body of heater overall appearance on body of heater, neatly.6) short net monolithic conductive structural safety is reliable.
