Abstract
The utility model discloses a turbulent flow suppressor for a continuous casting tundish, comprising an impact resistant plate installed in the steel flow impact zone at the bottom part of the continuous casting tundish; two vertical sides of the impact resistant plate along the continuous casting tundish are provided with a pair of turbulent suppression plates having smaller upper part, larger lower part and step-shaped opposite surfaces; and the turbulent suppression plates match with the transverse lateral walls of the continuous casting tundish along two transverse ends of the continuous casting tundish so as to form a bilateral trapezoid box for gradually reducing steel flow functions. The suppressor has simple structure, easy process, convenient operation and good turbulence resistance effect, and is particularly suitable for the technical field of steel continuous casting.
Description
Technical field
The utility model relates to the appurtenances in the continuous casting tundish, refers to a kind of continuous casting tundish turbulent flow TVS particularly.
Background technology
The continuous casting tundish is a transitional container between ladle and the crystallizer, and its major function is: storage, shunting molten steel, reduce ferrostatic pressure and remove field trash.In casting process, be from the flow feature of the beam of ladle: 1, speed height, kinetic energy is big, and it is serious that washing away of lining done in the centre job contract, easily causes secondary pollution; 2, the ladle beam is equivalent to " jet pump ", if seal bad meeting surrounding air is involved in molten steel, and breaking becomes the very little bubble of diameter, forms additional circulation, increases the weight of the secondary oxidation of molten steel; 3, the ladle beam enters the impact zone of tundish, is the zone of a high turbulence, causes tundish molten steel face to form " eyelet ", causes the secondary oxidation of molten steel and middle cinder inclusion to be involved in.
At these problems, U.S. LTV steel company has adopted a kind of anti-turbulent flow pad, be installed in the ladle beam impact zone of tundish bottom, use with weir, result after the use shows: anti-turbulent flow pad is greatly improved to middle Baogang liquid flow regime, make crystallizer molten steel total oxygen content value when stable casting, descend 20%, when changing ladle, descended 30%; Because the minimizing of the cinder inclusion that is mingled with in the molten steel makes the middle water containing opening clogging reduce 57%.Should make by corrosion resistant refractory material by anti-turbulent flow pad, " goldfish jar " formula that its cavity shape is rounded, profile is square.When the steel that makes a sheer drop from long nozzle flows to into anti-turbulent flow pad, can turn back upwards, steel stream when anti-turbulent flow is got discard again and the steel that gets off stream bump against, turbulence energy is weakened by circulation and reverse circulation repeatedly, thereby reduces the speed of rising steel stream.
A kind of tundish turbulent flow TVS of Vesuius company design is the uncovered peviform structure of octagon, and intracavity bottom and sidewall are wavy.In corrugated anti-turbulent flow basin, kinetic energy is minimized from the beam of ladle.
More than invention can solve the bigger problem of bringing of molten steel kinetic energy preferably, and is big but its weak point is anti-turbulator complex structure, machine-shaping difficulty.
Summary of the invention
The purpose of this utility model to provide exactly a kind of simple in structure, processing is easy, and the good continuous casting tundish turbulent flow TVS of anti-turbulence effects.
For achieving the above object, the continuous casting tundish turbulent flow TVS that the utility model is designed, comprise the impact-resistant panels that is arranged on continuous casting tundish bottom steel stream impact zone, described impact-resistant panels is provided with a pair of turbulent flow up-small and down-big, that opposite face is stepped and suppresses plate along vertical both sides of continuous casting tundish, described turbulent flow suppresses plate coincide along the transverse ends of continuous casting tundish and the lateral sidewalls of continuous casting tundish, constitutes the trapezoidal box like structure of bilateral of the steel energy of flow that decays gradually thus.
Further, the center line of the trapezoidal box like structure of described bilateral and the long nozzle central lines on the continuous casting tundish.
Operation principle of the present utility model is such: because this continuous casting tundish turbulent flow TVS is up-small and down-big by two, the turbulent flow of the stepped structure of opposite face suppresses plate and forms, when the ladle beam enters this continuous casting tundish turbulent flow TVS, after running into stepped sidewall, the kinetic energy of steel stream is decayed gradually, thereby reduce kinetic energy and speed that molten steel makes progress, prevent the formation of tundish liquid level " eyelet ", reduce the secondary oxidation and the volume slag of molten steel.And after the turbulent flow TVS installs, toast drying for standby with the tundish working lining, its operation is identical with mode of operation of the prior art.
Advantage of the present utility model is mainly reflected in following two aspects:
1, simple in structure, process easy, easy to operate;
2, anti-turbulence effects is good.
Description of drawings
Accompanying drawing is a kind of sectional structure schematic diagram of continuous casting tundish turbulent flow TVS.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Continuous casting tundish turbulent flow TVS shown in the figure, the turbulent flow of being made by the refractory material plate that comprises that two up-small and down-big, stepped structures of opposite face and size equate fully suppresses plate 4 and is arranged on the impact-resistant panels 5 of continuous casting tundish 3 bottom steel stream impact zone, turbulent flow suppresses plate 4 and is arranged at the vertical both sides of impact-resistant panels 5 along continuous casting tundish 3, and coincide along the lateral sidewalls of the transverse ends of continuous casting tundish 3 and continuous casting tundish 3, constitute the trapezoidal box like structure of bilateral of the steel energy of flow that decays gradually thus.Long nozzle 1 central lines on trapezoidal box like structure center line of above-mentioned bilateral and the continuous casting tundish 3 is beneficial to evenly to be applied to turbulent flow from the steel stream of long nozzle 1 ejection and suppresses on the plate 4.Above-mentioned turbulent flow suppresses plate 4 can directly build by laying bricks or stones on impact-resistant panels 5, also can build moulding with impact-resistant panels 5 is integrated.Adhering at the inner surface of continuous casting tundish 3 has working lining 2, and working lining 2 is made by refractory material.
After this continuous casting tundish turbulent flow TVS installs, toast drying for standby with bakie working lining 2, its operation is identical with mode of operation of the prior art.With respect to the anti-turbulent flow TVS of the peviform structure of anti-turbulent flow pad of " goldfish jar " formula and the uncovered band wave of octagon, that this continuous casting tundish turbulent flow TVS has is simple in structure, processing is easy, easy to operate, the anti-good characteristics of turbulence effects.
