Abstract
A tundish nozzle slag-guard ring, is a ring body, several salient are arranged around the upper surface of the ring body, the salient on the upper surface of the ring body is tooth profile structure; the salient can ensure the baking and air drafting effect of submerged nozzle while the tundish is baking, the refractory of tundish and other slag can be prevented from entering the nozzle simultaneous. The utility model has characteristics in that: while the molten steel of tundish is pouring, the slag-guard ring can automatically float upper and lower according to the height of the liquid steel level, so the vortex formed by steel slag of the molten steel is controlled to be brought into the mould, the slag of tundish is prevented from entering the nozzle. So the pouring quality of slab is not affected, and the braking quality of the submerged nozzle is ensured, the cost is low, the effect is well, and the labor intensity of operator is reduced.
Description
Technical field
The utility model relates to continuous casting of iron and steel equipment, particularly is used for continuous casting tundish mouth of a river pushing off the slag technology.
Background technology
The continuous casting tundish is the transferring equipment of accepting ladle molten steel and injecting molten steel to crystallizer, can reduce molten steel to the impact of crystallizer and splash, it also plays current stabilization and shunting action simultaneously, help non-metallic inclusion in the molten steel further come-up in tundish, played purify hot metal, be convenient to effect such as sequence casting.But in present production process, in the time of can not in time arriving continuous casting owing to preceding operation reason molten steel, the time regular meeting tundish quick baking takes place and prolong two kinds of situations of baking.Because of gas flow is bigger, can causes tundish paint, refractory material, clad to water material feeding and in bake process, come off during quick baking, flow directly into the mouth of a river (tundish lowest part); Can cause clad iron oxide cast to dissolve into liquid when prolonging baking and enter in the tundish upper nozzle, filling pipe end Yin Wendu is lower, can solidify these flowing liquids, directly stops up middle water containing opening, influences the normal cast of continuous casting.For this reason; to the tundish in each bake process; half an hour before using, take usually to cease fire and carry out mouth of a river spot check, after employing the method; though reduced the clogging at the mouth of a river; but can have influence on the baking quality of exhausting formula submersed nozzle again, because mouth of a river fracture can take place in the shock heating or quenching of submersed nozzle; shorten the service life of submersed nozzle greatly, also directly influenced normal cast when increasing production cost.
Summary of the invention
The purpose of this utility model is to provide a kind of tundish lining coating refractory material, clad of preventing to water foreign material such as material feeding and iron oxide flow into zone, the mouth of a river when baking middle water containing opening pushing off the slag circle.
For achieving the above object, the middle water containing opening pushing off the slag circle that the utility model provides, it comprises a ring body, be provided with several projectioies along the ring body upper surface, projection can guarantee baking, the exhausting effect of tundish when baking submersed nozzle, can prevent that slag thing such as tundish refractory material from entering in the mouth of a river simultaneously.
Further, described projection is a tooth-shape structure.
In addition, described projection and ring body are structure as a whole;
Described height of projection is 1/3~1/2 of a pushing off the slag circle height.
Advantage of the present utility model is, when the tundish pouring molten steel, use pushing off the slag circle of the present utility model, the pushing off the slag circle can float up and down according to the highly automated of liquid steel level, thereby contained that effectively the formed vortex of the slag in the molten steel is brought in the crystallizer, can stop effectively that the foreign material in the tundish enter the mouth of a river.At the casting quality that does not influence slab, guaranteed the baking quality of submersed nozzle again like this, it is low effective to have a cost, has also alleviated labor intensity of operating personnel simultaneously.

Fig. 2 is the schematic top plan view of Fig. 1.
Fig. 3 is user mode figure of the present utility model.
The number in the figure explanation
1 pushing off the slag circle
11 ring bodies, 111 upper surfaces, 12 projectioies
2 stoppers
3 tundish
31 permanent layer bricks, 32 brick cups, 33 operational layer bricks
4 filling pipe ends, 5 slide plates, 6 submersed nozzles, 7 molten steel
The specific embodiment
See also Fig. 1, Fig. 2, the middle water containing opening pushing off the slag circle 1 that the utility model provides comprises a ring body 11, is provided with several projectioies 12 along ring body 11; Described protruding 12 is tooth-shape structure, and projection 12 is structure as a whole with ring body 11; It highly is 1/2 of pushing off the slag circle 1 height, and stopper 2 passes pushing off the slag circle 1.
See also Fig. 3 again, it is depicted as user mode figure of the present utility model.
During use, pushing off the slag circle 1 is positioned over filling pipe end 4 tops in the tundish 3, stopper 2 passes pushing off the slag circle 1 and cooperates with filling pipe end 4; Tundish 3 inner surfaces are made of refractory material, coating such as permanent layer brick 31, operational layer brick 33, brick cups 32; When tundish 3 pouring molten steels, pushing off the slag circle 1 can float up and down according to the highly automated of molten steel 7 liquid levels, can stop effectively that the foreign material in the tundish 3 enter submersed nozzle 6, thereby effectively contain the formed vortex of slag in the molten steel 7 and be brought in the crystallizer.
