Abstract
The utility model provides a sheet billet fast-replacing submerged nozzle. The sheet billet fast-replacing submerged nozzle comprises a nozzle body and a water outlet formed in the bottom of the nozzle body. The sheet billet fast-replacing submerged nozzle is characterized in that the nozzle body comprises a straight line section arranged at the upper end and a horn section connected to the straight line section. An upper caliber and a lower caliber of an inner cavity of the straight line section are equal, the barrel diameter of the upper end of the horn section is smaller than that of the lower end of the horn section, and the top and the bottom of the horn section are in smooth transition. The water outlet is in a flat shape. Compared with the prior art, the sheet billet fast-replacing submerged nozzle has the advantages that the sheet billet fast-replacing submerged nozzle is suitable for continuous casting of a sheet billet with a narrow crystallizer, molten steel can flow more stably inside the nozzle and at the outlet, the molten steel can reasonably flow in the crystallizer, an unstable state of a molten steel liquid level is reduced, and therefore the quality of the billet is improved. The sheet billet fast-replacing submerged nozzle has good thermal shock resistance, the service life of the submerged nozzle is prolonged, and the risk of suspending casting is reduced.
Description
Technical field
The utility model relates to the submersed nozzle that a kind of continuous casting is used thin stock plate quick-changing type.
Background technology
Continuous casting has become the major way of modernization iron and steel enterprise STEELMAKING PRODUCTION.In continuous casting technology, for improving slab quality, be typically provided with submersed nozzle between tundish and crystallizer, its Main Function is: (1) prevents splashing of secondary oxidation of steel, nitrogenize and molten steel; (2) regulate MOLTEN STEEL FLOW state and injection rate; (3) non-metallic inclusion that prevents covering slag is involved in molten steel, simultaneously the floating that promotes foreign substance in molten steel is played an important role; (4) opposite side casting throwing lumber recovery and slab quality have decisive influence.
The modal configuration of existing quick-changing type submersed nozzle be one with the refractory material conical tube in zirconium matter slag line layer and the hole that spues, this conical tube shape be mainly used in slab, generous sheet billet continuous casting demand.As shown in Figure 1, staving 1 is the main part at the mouth of a river, and molten steel passes staving 1 and flows at bowl inner chamber 2, is flowed out by discharge opening 3 at last.Although this structure has good practical function, and be not suitable for the narrow sheet blank continuous casting of crystallizer.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of thin stock plate quick-changing type submersed nozzle is provided.
The purpose of this utility model is achieved through the following technical solutions:
Thin stock plate quick change submersed nozzle, comprise mouth of a river body and be arranged on body bottom, mouth of a river delivery port, described mouth of a river body comprises the straightway that is arranged on the upper end and is connected in the loudspeaker section composition of straightway, the inner chamber bore of described straightway is unanimous between the higher and lower levels, the barrel dliameter upper end of described loudspeaker section is less than the lower end, and be rounding off from top to bottom, described delivery port is pancake.
Preferably, the outer surface of described straightway is cylindric, and the outer surface of described loudspeaker section is pancake, and the cross section is tubaeform.
Preferably, described delivery port cross section is circular, quadrangle or ellipse.
Preferably, described delivery port be arranged on the side of mouth of a river body bottom or with mouth of a river inner chamber on same axis, described delivery port is provided with one at least.
Preferably, described straightway is arranged on the top of slag line layer.
The beneficial effects of the utility model are mainly reflected in: be applicable to the narrow sheet blank continuous casting of crystallizer, make steel stream in inside, the mouth of a river and exit, better stability be arranged, make molten steel reasonably to flow in crystallizer, reduced the labile state of liquid steel level, thereby improved the quality of steel billet, thermal shock resistance is preferably arranged, extended the life-span of submersed nozzle, reduced and interrupted watering inferior risk.

The specific embodiment
The utility model has disclosed a kind of thin stock plate quick change submersed nozzle, as shown in Figure 2, comprises mouth of a river body and is arranged on the delivery port 13 of mouth of a river body two bottom sides.
Certainly, the quantity of delivery port and position can arrange as required.Described delivery port 13 also can be provided with one, only be arranged on the bottom, namely with mouth of a river chamber body on same axis.
Described mouth of a river body comprises that the straightway 1 that is arranged on the upper end and the loudspeaker section that is connected in straightway 1 12 form.Inner chamber 11 bores of described straightway 1 are unanimous between the higher and lower levels, and outer surface is cylindric.Such structure has well realized the effect of quick change.Concrete, described straightway 1 is arranged on the top of slag line layer, and the outer surface profile of described loudspeaker section 12 is pancake, and the cross section is tubaeform.Structure of the present utility model both had been suitable for the continuous casting of the narrow sheet billet of crystallizer, can engage with tundish upper nozzle or the slide plate of various shapes again, and enough mechanical strengths are arranged, and can also carry out argon gas-sealed, and isolated air improves the quality of products.
The barrel dliameter upper end of described loudspeaker section 12 is less than the lower end, and is rounding off from top to bottom, and the lumen openings in the mouth of a river is consistent with it, also is the tubaeform of rounding off.Described delivery port 13 is pancake.Extremely shown in Figure 5 in conjunction with Fig. 3, described delivery port 13 cross sections can arbitrarily arrange as required, can be chosen as circle, quadrangle or ellipse etc., make steel stream in inside, the mouth of a river and delivery port, better stability be arranged, make molten steel reasonably to flow in crystallizer, reduce the labile state of liquid steel level, thereby improved the quality of steel billet, thermal shock resistance is preferably arranged, extended the life-span of submersed nozzle, reduced and interrupted watering inferior risk.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the claimed scope of the utility model.
