Abstract
The invention provides an improved tundish retaining wall which is characterized by comprising a middle flow baffling plate and inclined buffering plates which are spliced at left and right sides of the middle flow baffling plate, wherein a reversed ladder-shaped structure without a bottom edge is spliced by the middle flow baffling plate and the inclined buffering plates; and the inclined buffering plates at left and right sides are uniformly provided with a plurality of flow leakage holes. The reversed ladder-shaped structure without the bottom edge is arranged, so that the improved tundish retaining wall is effectively prevented from being cracked and the service life is prolonged.
Description
Technical field
The present invention relates to tundish protector in the blast furnace steel-making field, relate in particular to a kind of improved weir and dam in tundish.
Background technology
Tundish is a refractory material container of using in the short flow process steel-making, at first accepts to water down molten steel from ladle, and then is assigned in each crystallizer by middle water containing opening and goes; Iron and steel is being brought into play very important effect as a kind of important basic raw material in the economic development of countries in the world, because MOLTEN STEEL FLOW is inhomogeneous in the tundish, the interior impurity of tundish is more; Be easy to generate eddy current in the tundish, it is bigger that the tundish wall is washed away, and tundish is generally shorter service life; The tundish baffle plate generally all is set in tundish on the market, effectively controls the impact of molten steel, effectively raise the service life of tundish tundish bag wall; But mostly the impact zone baffle plate of operated by rotary motion is plate shaped on the market; Under the molten steel percussion, occur phenomenon of rupture easily, service life is shorter, effectively uses the stove number to be merely the 5-10 stove; Steel quality is difficult to guarantee, tundish shortens service life greatly.
Summary of the invention
The present invention is directed to prior art problems, a kind of long service life, anti-fracture improved weir and dam in tundish are provided.
The present invention is for solving the problems of the technologies described above; Following technical scheme is provided: a kind of improved weir and dam in tundish; The buffer board that flow-stopping plate, splicing are tilted in the middle flow-stopping plate left and right sides in the middle of it is characterized in that comprising; The three is spliced into the inverted trapezoidal structure on a no base, evenly offers some discharge orifices on the left and right sides inclination buffer board.
As of the present invention further preferred, it is 3-5 that discharge orifice is preferably, and has effectively reduced the surge of both sides buffer boards through this kind setting, effectively prevents the fracture of weir and dam in tundish.
As of the present invention further preferred, buffer board angle of inclination, the left and right sides is preferably 120 °-150 °, makes the surge of the middle flow-stopping plate of weir and dam in tundish be dispersed to the both sides buffer board through this kind setting, has improved the bonding strength of weir and dam in tundish greatly.
As of the present invention further preferred, discharge orifice is circular or square, through offering discharge orifice, effectively alleviates both sides buffer board surge.
As further improvement of the present invention, middle bay stream plate center is provided with the circular arc projection, through this kind setting, better cushions the impact of molten steel, improves service life.
The weir and dam in tundish of the inverted trapezoidal structure through no base is set of the present invention effectively prevents fracture, increases the service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of improved weir and dam in tundish; The buffer board 2 that flow-stopping plate 1, splicing are tilted in middle flow-stopping plate 1 left and right sides in the middle of comprising, the three is spliced into the inverted trapezoidal structure on a no base, evenly offers some discharge orifices 3 on the left and right sides inclination buffer board 2; Discharge orifice 3 is 3-5; Buffer board 2 angles of inclination in the left and right sides are 120 °-150 °, and discharge orifice 3 is circular or square, and middle bay stream plate 1 center is provided with circular arc projection 4.
Claims (5)
1. an improved weir and dam in tundish is characterized in that comprising middle flow-stopping plate, splices the buffer board that tilts in the middle flow-stopping plate left and right sides, and the three is spliced into the inverted trapezoidal structure on a no base, evenly offers some discharge orifices on the left and right sides inclination buffer board.
2. a kind of improved weir and dam in tundish according to claim 1 is characterized in that discharge orifice is 3-5.
3. a kind of improved weir and dam in tundish according to claim 1 is characterized in that buffer board angle of inclination, the left and right sides is 120 °-150 °.
4. a kind of improved weir and dam in tundish according to claim 1 is characterized in that discharge orifice is circular or square.
