Abstract
The utility model discloses a combined type integral current stabilizer for an irregular tundish. The combined type integral current stabilizer is an open hollow combined integral structure quasi to a quarter of a cylinder, which is formed by three side plates and one bottom plate (8) and has a big mouth and a small bottom, the three side plates include a guard plate (1), a guard plate (3) and a current guide plate (2), the current guide plate (2) is in an arc structure, and the bottom surface (7) of an inner cavity is provided with a primary constant-current stabilizer which is in a hollow necking barrel structure. The utility model solves the problem that the excellent current control device can not be used by the multi-strand irregular tundish with a smaller impact zone, has the characteristics of easy construction, high corrosion and erosion resistance and the like and enables the molten steel temperature and components to be fully uniform through primary current stabilization, secondary stabilization and reasonable current distribution so as to be good for impurities to float upwards and hereby improve the blank casting quality of the multi-strand irregular tundish.
Description
Technical field
The utility model relates to the tundish flow straightener that a kind of iron and steel metallurgical industry uses in steelmaking process, particularly relate to a kind of a kind of whole flow straightener of special-shaped tundish combined type that is used for that secondary current stabilization, water conservancy diversion, protection impact zone side wall function are one that collects.
Background technology
Development along with steel industry and continuous casting technology, produce high-quality variety steel and become the target that each iron and steel enterprise chases, the setting of current stabilization such as flow straightener, slag blocking wall, flow control device is a necessary means that improves steel product quality, but these configurations can only be applied to the shape comparison rule as in inverted T-shaped continuous casting tundish and the rectangle continuous casting tundish, and for the irregular special-shaped continuous casting tundish of multithread number form shape, several current stabilizations, flow control device are set within it but can't desirablely realize.
Chinese patent CN2794695Y has disclosed a kind of continuous casting tundish integrated impact plate slag blocking wall, the continuous casting tundish integrated impact plate slag blocking wall of this disjunctor die casting structure has the function of shock plate and slag blocking wall simultaneously, raising to a certain degree the quality of strand, but because it does not have good current stabilization effect to cause easily that molten steel splashes in the steel pouring process, simultaneously since its reasons in structure yield rate low, be not easy transportation.
Chinese patent CN201140273Y has disclosed a kind of tundish multifunctional integral flow straightener, this six terrace with edge overall structure flow straighteners have improved Chinese patent CN2794695Y because reasons in structure and yield rate are low, the problem that is not easy to transport, but fully do not solve the problem that molten steel splashes in the steel pouring process, the kind that is suitable for tundish bag type simultaneously is also more limited.
The purpose of this utility model is to provide a kind of further improvement at above-mentioned integrated impact plate slag blocking wall or tundish usefulness multifunctional integral flow straightener.
Summary of the invention
The current stabilization flow control device is set reaching the goal of the invention of producing high-quality variety steel in the multithread number abnormity continuous casting tundish in order to solve, it is a kind of whole flow straightener of special-shaped tundish combined type that is used for of one that the utility model provides a kind of secondary current stabilization, water conservancy diversion, protection impact zone side wall function of collecting.
A kind of whole flow straightener of special-shaped tundish combined type that is used for, it is characterized in that: this device is three side plates and the hollow uncovered composite monolithic structure of class quadrant post that base plate 8 constitutes, the big bottom of its oral area is little, described three side plates comprise backplate 1, backplate 3 and deflector 2, described deflector 2 is an arcuate structure, inner chamber bottom surface 7 is provided with constant-current stabilizer 9 No. one time, and a described constant-current stabilizer 9 is hollow closing in barrel shaped structure.
The utility model also can be done following improvement:
Described deflector 2 is provided with auxiliary pod apertures 6 and the function pod apertures 4,5 according to special-shaped middle water containing opening position and the setting of continuous casting parameter optimization.
The material of described flow straightener is magnesia or magnalium matter or magnalium matter or alumina-silica or high alumina matter.
The utility model has the advantages that the problem that the less relatively multithread abnormity tundish of impact zone can't use good flow control device that solved, it is simple to have construction simultaneously, characteristics such as anti-erosion and erosion resistibility are strong, and can make liquid steel temperature and composition full and uniform by current stabilization, secondary current stabilization and a reasonable diffluence, help inclusion floating, thereby improve the slab quality of multithread abnormity tundish.

The specific embodiment
Below, describe preferred embodiment of the present utility model in detail with reference to accompanying drawing.Need to prove before this, employed term or word can not limited interpretation be common implication or the implication in the dictionary in this specification and claims book, and should be based in order to illustrate that in the best way principle that its practical novel inventor can suitably define the notion of term is interpreted as meeting the implication and the notion of the utility model technological thought.Thereupon, the structure of representing in embodiment that this specification is put down in writing and the accompanying drawing is one of the utility model most preferred embodiment, can not represent technological thought of the present utility model fully, therefore should be understood that for the utility model, to have various equivalents and the variation that to replace.
See Fig. 1, Fig. 2 is suitable for about 25T four machines, four streams, mouth of a river spacing is a kind of whole flow straighteners of special-shaped tundish combined type that are used for of 1300 millimeter shown in Fig. 3.
See Fig. 1, Fig. 2, a kind of whole flow straightener of special-shaped tundish combined type that is used for of Fig. 3; This device is provided with 2 three side plates of deflector and the hollow uncovered class quadrant post composite monolithic structure that base plate 8 constitutes of auxiliary pod apertures 6 and function pod apertures 4,5 by backplate 1, backplate 3 with for its of arcuate structure, the big bottom of its oral area is little, constant-current stabilizer 9 once on the inner chamber bottom surface 7, device 9 is hollow closing in barrel shaped structure. Described backplate face 2 is an arcuate structure, and it is provided with auxiliary pod apertures 6 and function pod apertures 4,5 according to special-shaped middle water containing opening position and the setting of continuous casting parameter optimization, evenly shunting to greatest extent. A described constant-current stabilizer 9 is hollow closing in barrel shaped structure, and molten steel enters the class quadrant post cavity that is surrounded by backplate 1, backplate 3 and deflector 2 after installing 9 current stabilizations, forms the secondary current stabilization. Described a kind of material that is used for the whole flow straightener of special-shaped tundish combined type is magnesia or magnalium matter or magnalium matter or alumina-silica or high alumina matter.Solved the problem that the less relatively multithread abnormity tundish of impact zone can't use good flow control device, it is simple to have construction simultaneously, characteristics such as anti-erosion and erosion resistibility are strong, and can make liquid steel temperature and composition full and uniform by current stabilization, secondary current stabilization and a reasonable diffluence, help inclusion floating, thereby improve the slab quality of multithread abnormity tundish.
