Description
Technical field
Fiber tube is fed in the refining furnace wire feeder outlet that the utility model relates to a kind of improvement, belongs to steel-making refining unit technical field.
Background technology
Ladle wire feeding technology is the novel ladle refining techniques starting the seventies in last century to rise, it is that Ca, Al, Si-Ca, Ca-Al etc. are oxidizable or alloy in lightweight makes cored-wire or pure metal line, then the depths of ladle molten steel is fed into by wire feeder system, so that the technology to refining treatment such as the efficient deoxidation of molten steel, alloying, nonmetal inclusion sex change.
Concise wire feeder system common is at present primarily of wire feeder body, inlet wire conduit, lifting device, control device, outlet is fed fiber tube and is fed the part compositions such as fiber tube conduit, wherein outlet hello fiber tube mainly with rational input angle and highly successfully can be imported in molten steel in order to ensure heart yearn, more satisfactory state is that outlet hello fiber tube caliber is less, distance steel liquid level is nearer, the guidance quality of heart yearn is better, yield of alloy is higher, but because outlet hello fiber tube caliber is less in reality, heart yearn frictional force is larger, especially as easy as rolling off a logly during two-wire line feeding motor overload is caused, occur to shut down phenomenon, for this reason, feed silk precision and can only reduce outlet for improving and feed distance between fiber tube and molten steel, and distance reduce after due to the hyperthermia radiation of molten steel, and molten steel sustained reaction, the slag that steel ladle bottom argon blowing causes splashes, can increase outlet feed fiber tube high temperature scaling loss or because of slag splash cause outlet feed fiber tube dry slag, block outlet and feed fiber tube, finally cause line feeding failure.Chinese patent 201762371U discloses a kind of novel " alloy-wire conduit of wire feeder ", this patent by its feed fiber tube outer setting inlet channel, outlet conduit, enter argon pipeline one and enter argon pipeline two, strengthen the cooling of feeding fiber tube, although the method can reach the object of outlet being fed to fiber tube cooling, but owing to increasing external pipe, there is design complicated, cooling efficiency is low, uses the defects such as inconvenient.Therefore, manufacture that a kind of cooling efficiency is high, high temperature scaling loss is few, can prevent the outlet of high-temperature steel slag dry slag from feeding fiber tube necessary.
Utility model content
Fiber tube is fed in the refining furnace wire feeder outlet that technical problem to be solved in the utility model is to provide a kind of improvement, by improving the water-cooled of feeding fiber tube structure and realizing feeding fiber tube, cooling efficiency is high, high temperature scaling loss is few, can effectively prevent high-temperature steel slag dry slag, improve and feed the fiber tube life-span, solve background technology defect.
The technical scheme solved the problems of the technologies described above is:
A fiber tube is fed in the refining furnace wire feeder outlet of improvement, and comprise and feed fiber tube body, its improvements are: described hello fiber tube body is bilayer structure, and comprise interior pipe, outer tube and dividing plate that length is identical, inner and outer tubes form circular annular seal space; Dividing plate is positioned at the two ends of pipe arbitrary diameter, and be fixedly connected with outer tube wall along feeding fiber tube body length direction with outer wall of inner tube, the lower partition has limbers; Circular annular seal space is divided into into water cooling room and goes out water cooling chamber by dividing plate, and the outer tube on water inlet cooling room top is communicated with inlet channel, and the outer tube going out water cooling chamber top is communicated with outlet conduit.
Fiber tube is fed in the refining furnace wire feeder outlet of above-mentioned a kind of improvement, and described diameter of inner pipe is identical with feeding fiber tube conduit caliber, and length is greater than the distance 350 ~ 500mm of water cooled cover top to ladle liquid level.
The beneficial effects of the utility model:
Because fiber tube of feeding of the present utility model have employed water cooling plant, slow down the high bake of molten steel, can shorten and feed distance between fiber tube and molten steel face, the running helter-skelter of heart yearn when preventing from feeding silk, achieves fixed point and feeds silk, improve yield of alloy; The utility model cooling area is large, and efficiency is high, prevents the high temperature scaling loss of feeding fiber tube, improves the work-ing life of feeding fiber tube, decreases slag splash to what feed that fiber tube causes and is stained with slag obstruction accident, improve wire feeder operating rate, saved production cost.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model vertical view;
Fig. 3 is the utility model left view and bottom sectional view;
A-A direction view of Fig. 4 Fig. 3;
Fig. 5 is that the utility model uses schematic diagram;
Be labeled as in figure: interior pipe 1, outer tube 2, dividing plate 3, limbers 4, water inlet cooling room 5, go out water cooling chamber 6, inlet channel 7, outlet conduit 8, feed fiber tube conduit 9, water cooled cover 10, ladle 11.
Embodiment
Fig. 1 ~ Fig. 4 shows, it is bilayer structure that the utility model feeds fiber tube body, comprise the identical interior pipe 1 of length, outer tube 2 and dividing plate 3, the diameter of interior pipe 1 is identical with the caliber of feeding fiber tube conduit 9, and length is greater than the distance 350 ~ 500mm of liquid level in water cooled cover 10 caping to ladle 11; Interior pipe 1 and outer tube 2 form circular annular seal space; Dividing plate 3 is arranged in the two ends of pipe 1 diameter vertical with inlet and outlet pipe lines, and be fixedly connected with the inwall of outer tube 2 along feeding fiber tube body length direction with the outer wall of interior pipe 1, the lower partition has limbers 4; Circular annular seal space is divided into into water cooling room 5 and goes out water cooling chamber 6 by dividing plate 3, and the outer tube on water inlet cooling room 5 top is communicated with inlet channel 7, and the outer tube going out water cooling chamber 6 top is communicated with outlet conduit 8.
Referring to Fig. 5, water-cooled of the present utility model is fed fiber tube and is connected with hello fiber tube conduit 9, when needing in production to feed silk, feeding fiber tube conduit 9 decline drives water-cooled to feed fiber tube decline, feed fiber tube by water-cooled and extend into water cooled cover less than 10, carry out apart from 20mm place, molten steel face feeding silk operation, the water coolant that inlet channel 7 passes into enters out water cooling chamber 6 through water inlet cooling room 5 through the limbers 4 of the lower partition, finally flow out through outlet conduit 8, realize recirculated water to the cooling of feeding fiber tube; Because the length of feeding fiber tube is greater than the distance 350 ~ 500mm in water cooled cover 10 caping to ladle 11 between liquid level, when feeding silk, feed fiber tube and all have employed water-cooled at water cooled cover 10 with lower part, decrease the high temperature scaling loss of feeding fiber tube well, avoid slag splash steel bonding to the blocking accident of feeding fiber tube, improve the intensity of feeding fiber tube after adopting water-cooled, prevent the distortion of feeding fiber tube high temperature, extend the work-ing life of feeding fiber tube.After hello silk terminates, feed fiber tube conduit 9 and rise, drive water-cooled to feed fiber tube and rise, water-cooled hello fiber tube is recovered to waits for position, waits for that next time feeds silk.
