Abstract
The utility model discloses a water flow stabilizer for molten steel in tundish, which belongs to the technical field of continuous casting equipment for steel-producing, and aims at preventing molten steel from splashing at the beginning of casting, improving the service life of tundishes, and improving the continuous casting number. The technical scheme is as follows: the water flow stabilizer for molten steel in tundish consists of a flow stabilizer base, a working layer guard board and an impact board. The flow stabilizer base is of a drum shape; the bottom surface of the flow stabilizer base is of a drum; the circle of the flow stabilizer base is an annular side wall; the flow stabilizer base is connected with the working layer guard board is connected on a side wall; the working layer guard board is a square in which three sides are connected and one side is opened; the lower end of the working layer guard board is smoothly and transitionally connected with the annular side wall of the flow stabilizer base; and the impact board is arranged on the bottom surface of the flow stabilizer base. The water flow stabilizer for molten steel in tundish has the advantages as follows: the impact board can resist the impact of high-temperature molten steel, protect the bottom of the tundish, and improve the service life of the tundish; the flow stabilizer base is designed into a drum, thus preventing the molten steel from splashing at the beginning of casting; the working layer guard board can protect the working layers of the tundish, so that the continuous casting number is increased; and the water flow stabilizer for molten steel in tundish is suitable for resisting the impact of the molten steel in the tundish of continuous casting machines for various square billets, round billets and shaped billets.
Description
Technical field
The utility model relates to a kind of tundish molten steel flow straightener, belongs to the steel-making continuous casting equipment technical field.
Background technology
In steel mill square billet machine continuous casting production process, water smoothly for guaranteeing to open, turn over when preventing ladle and spatter toward tundish injection molten steel, need the tundish impact zone that the molten steel flow straightener is set, at present widely used is according to square billet tundish impact zone design shock plate.Find that in use though this shock plate can protect the tundish bottom not burnt, molten steel turns over easily and spatters, and burns out sled mechanism, even causes equipment and personal safety accident when ladle injects.And to after the long-time use, tundish shock zone bag wall corrodes serious, has limited the raising of Lian Lalu number, even the serious accident of tundish slag lining bottom pour ladle occurred.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of steel-making continuous casting with tundish molten steel flow straightener, and it can prevent to open when watering molten steel and turn over and spatter, improve tundish service life, improve to connect and draw the stove number, reduce anti-material and iron and steel stock consumption.
The technical scheme that solves the problems of the technologies described above is:
A kind of tundish molten steel flow straightener, it is made up of flow straightener base, working lining backplate and shock plate, the flow straightener base is circular tubbiness, at the bottom of the bottom surface is round tank, circumference is an annular sidewall, and the sidewall top is connected with the working lining backplate, and the work backplate is the square of three connections and openings at one side, its lower end is connected with the annular sidewall rounding off of flow straightener base, and shock plate is placed on the bottom surface of flow straightener base.
Above-mentioned tundish molten steel flow straightener, it is the 77-82 degree that there are the angle of flare, angle in the bottom surface of the sidewall of described flow straightener base and working lining backplate and flow straightener base.
Above-mentioned tundish molten steel flow straightener, the both sides, upper end of described working lining backplate are equipped with suspension ring.
Above-mentioned tundish molten steel flow straightener, described shock plate adopt magnalium carbon material to make, and the working lining backplate is made for the magnalium carbon refractory.
The utlity model has following advantage:
1. shock plate adopts magnalium carbon material, can resist the impact of high-temperature molten steel, at the bottom of the protection tundish bag, improves tundish service life;
2. the current stabilization base is the design of circular tubbiness, can prevent to open when watering molten steel and turn over and spatter, and protection ladle sled mechanism and tundish stopper control system, the personnel of preventing scald;
3. the working lining backplate is the magnalium carbon refractory, can protect bakie working lining, and slag line adopts antiscour magnalium carbon refractory, can resist the tundish molten steel and wash away for a long time, prevents that slag line from partly corroding, and has improved the Lian Lalu number;
4. suspension ring can prevent that flow straightener from damaging in handling and installation process;
5. the utility model impacts applicable to resisting various types of square billets, circle base and special-shaped billet continuous casting machine tundish molten steel.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Mark is as follows among the figure: flow straightener base 1, working lining backplate 2, suspension ring 3, shock plate 4.
The specific embodiment
Show among the figure that the utility model is made up of flow straightener base 1, working lining backplate 2, suspension ring 3, shock plate 4.Flow straightener base 1, working lining backplate 2, suspension ring 3, shock plate 4 are as a whole, are convenient to make and install.During work, in the middle of flow straightener and working lining, fill the dry type material, closely contact, can prevent that flow straightener floats on the liquid steel level in the steel pouring process with working lining.
On 2 connections of working lining backplate and the flow straightener base 1, its three side sealing closes connection, an opening.Working lining backplate 2 has the flare angle with the bottom surface of flow straightener base 1, and the angle number of degrees are the 77-82 degree, and the angle of the embodiment that shows among the figure is 80 degree.
Working lining backplate 2 can be according to tundish impact zone shaped design; take into full account the cooperation of working lining backplate 2 and tundish impact zone working lining size; according to the two kinds of different heat expansion coefficient of anti-material design fit dimensions, prevent that promptly backplate from bursting, bakie working lining can adequately protect again.Working lining backplate 2 slag lines partly adopt magnalium carbon material, can resist the dual of molten steel and liquid steel slag and wash away.In an embodiment of the present utility model, water steel continuously after 20 hours, slag line partly also has certain thickness, and working lining is intact substantially, has reached to improve to connect to draw stove to count effect.
In an embodiment of the present utility model, tundish waters steel stove number continuously and brought up to more than 20 hours by original 12 hours, has reached the purpose that reduces anti-material use cost and iron and steel stock consumption.
