Abstract
The invention provides a novel continuous casting tundish. The novel continuous casting tundish comprises a tundish container, a liquid inlet pipe arranged in the top surface of the tundish container and an outlet pipe arranged at the other end of the bottom of the tundish container, wherein the tundish container also comprises a bubble generator arranged between the outlet pipe and the liquid inlet pipe; and bubbles generated by the bubble generator are used for changing the flow direction of molten steel between the liquid inlet pipe and the outlet pipe. The novel continuous casting tundish has the advantages of reducing nitrogen absorption of the molten steel in the tundish, promoting foreign impurities in the molten steel in the tundish to float upwards, reducing non-metal foreign impurities flowing into a crystallizer, improving temperature uniformity and whole mixing effect of the molten steel, thus improving the quality of the molten steel.
Description
Technical field
The present invention relates to a kind of novel continuous casting tundish.
Background technology
In steel and iron industry technical development process, continuous casting has become the main mode of modernized iron and steel enterprise STEELMAKING PRODUCTION.At present, tundish structure used in iron and steel enterprise's steel-making is simple, as shown in Figure 1, it is the container 3 of a refractory material, molten steel enters near the feed tube 1 of tundish bottom from inserting tundish, and the tundish bottom other end is provided with molten steel effuser 2, makes molten steel lead to crystallizer by effuser 2.Non-metallic inclusion in the uncontrollable molten steel of the tundish of this structure makes the non-metallic inclusion that flows into crystallizer too much, causes stifled slag easily, deslagging is had some setbacks, influence the operate as normal of tundish, even influence slab quality, cause the defective deficiency that waits of steel grade.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of novel continuous casting tundish is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of novel continuous casting tundish, comprise the tundish container, insert the feed tube and the effuser that is arranged on the tundish container bottom other end of tundish container top surface, described tundish container also comprises a bubble generator that is arranged between effuser and the feed tube, and the bubble that described bubble generator generates is in order to change the MOLTEN STEEL FLOW direction between described feed tube and the effuser.
Further, above-described a kind of novel continuous casting tundish, wherein said bubble generator is fixed on the bottom interior wall of tundish container.
Further, above-described a kind of novel continuous casting tundish, wherein said bubble generator adopts welding or is threaded fixing.
Further, above-described a kind of novel continuous casting tundish, the feed tube bottom of described feed tube stretches to the middle part of described tundish container, and the effuser upper end of described effuser and the bottom of tundish container are at grade.
Beneficial effect of the present invention is mainly reflected in: this novel continuous casting tundish has reduced the suction nitrogen of tundish molten steel, can help floating foreign in the tundish molten steel, reduce the non-metallic inclusion that flows into crystallizer, improve the uniformity of liquid steel temperature, strengthen the overall effect of mixing of molten steel, thereby improve the quality of molten steel.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: continuous casting tundish schematic diagram of the prior art.
Fig. 2: novel continuous casting tundish schematic diagram of the present invention.
Wherein:
1 feed tube, 2 effusers, 3 tundish containers
21 effusers upper end, 4 bubble generators, 11 feed tube bottoms
The specific embodiment
The present invention has disclosed a kind of novel continuous casting tundish, as shown in Figure 2, a kind of novel continuous casting tundish, comprise tundish container 3, insert the feed tube 1 and the effuser 2 that is arranged on the tundish container 3 bottom other ends of tundish container 3 end faces, feed tube 1 and effuser 2 are separately positioned on the both sides of tundish container 3, make molten steel that enough mixed flow distances be arranged in tundish.
The feed tube bottom 11 of described feed tube 1 stretches to the middle part of described tundish container, and the effuser upper end 21 of effuser 2 and the bottom of tundish container 3 are at grade.The bottom surface inwall is provided with a bubble generator 4 in the middle of tundish container 3 bottom surface effusers 2 and the feed tube 1, and the bubble that described bubble generator generates is in order to change the MOLTEN STEEL FLOW direction between described feed tube and the effuser.Described bubble generator 4 adopts welding or is threaded fixing.
The course of work of the present invention is as follows: molten steel enters tundish from feed tube 1; bubble generator 4 work; make molten steel in tundish, mix; field trash wherein is owing to the bubble that bubble generator 4 produces floats; tundish container 1 surface is provided with the tundish covering slag, and field trash is trapped in the covering slag, and the molten steel after non-metallic inclusion reduces enters effuser 2; flow in the crystallizer, guarantee the quality of strand.
The present invention compared with prior art has the following advantages: novel continuous casting tundish has reduced the suction nitrogen of tundish molten steel, the bubble generator 4 that is increased can help floating foreign in the tundish molten steel, reduce the non-metallic inclusion that flows into crystallizer, improve the uniformity of liquid steel temperature, strengthen the overall effect of mixing of molten steel, thereby improve the quality of molten steel.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
