Abstract
The utility model mainly relates to a slag blocking wall of a tundish for square billet continuous casting. The slag blocking wall of the tundish for square billet continuous casting comprises a planar wall body and an oblique wall body which is arranged on one side of the planar wall body, liquid steel holes are formed in the planar wall body and the oblique wall body respectively, one end of the oblique wall body is connected with one end of the planar wall body, so that an L-shaped structure is formed, and a thickening layer which protrudes out of wall surfaces is arranged on the position of a slag line, above the liquid steel holes, on the wall surfaces of the planar wall body and the oblique wall body. According to the slag blocking wall of the tundish for square billet continuous casting, due to the fact that the slag blocking wall is of the L-shaped structure, a flow field of liquid steel can be more stable, furnace slag can be separated from the liquid steel conveniently, and the cleanliness of the liquid steel is improved; due to the fact that the corner position where the planer wall body is connected with the oblique wall body is of an arc structure, scouring of eddies to the corner position is effectively reduced, and the overall scouring resistance of the slag blocking wall is improved; due to the fact that the thickening layer is arranged on the position of the slag line of the slag blocking wall, corrosion of the liquid steel to the planar wall body and the oblique wall body is effectively relieved, and the overall corrosion resistance of the slag blocking wall is improved.
Description
Technical field
The utility model relates to tundish metallurgy refractory for continuous casting, is specifically related to a kind of billet continuous casting tundish slag wall.
Background technology
Along with the progress of Technology of Tundish Metallurgy, to improve centered by the cleanliness factor of molten steel, from improving MOLTEN STEEL FLOW state, take, reach that to reduce molten steel slag inclusion thing be object, slag blocking wall is set in tundish.Slag blocking wall is divided into two by tundish and had not only connected each other but also separate region: impact zone and beam district.The effect of slag blocking wall on tundish metallurgy is as follows: 1, become the movement locus that steel flows, extend the time of staying of steel stream in tundish, make the field trash in molten steel have sufficient time collision, assemble, float, purify hot metal.2, the molten steel fluidised form changing in tundish distributes, and makes molten steel flow field reach optimum state.3, reduce stagnant area, expand current stabilization district.4, steel is flow to reach the time at each shunting mouth of a river of tundish basic identical, with even temperature of each stream, reduce bleedout and stopper bonding phenomenon.At present tundish slag wall is traditionally arranged to be U-shaped, V-arrangement, the structure such as trapezoidal, continuous casting is opened while watering molten steel in ladle and is injected fast tundish, forms strong eddy current and turbulent flow in tundish impact area, and the flow regime of molten steel is more disorderly, slag is easily involved in molten steel, affects the cleanliness factor of molten steel; The eddy current simultaneously forming, washes away seriously the resistance to material of slag blocking wall slag lining, and along with the increase of pouring furnace number, slag blocking wall slag lining corrodes and aggravates, and easily causes the slag blocking wall slag lining phenomenon that even slag line comes off with upper part integral body of boring a hole.
Utility model content
The purpose of this utility model is to provide a kind of billet continuous casting tundish slag wall, and this slag blocking wall is simple in structure, is conducive to the separated of slag and molten steel, and erosion resistibility and resistance to erosiveness are strong, and whole service life is long.
The utility model is for solving the problems of the technologies described above, the technical scheme providing is: a kind of billet continuous casting tundish slag wall, comprise plane body of wall and the inclined-plane body of wall that is arranged on plane body of wall one side, on plane body of wall and inclined-plane body of wall, be provided with steel outlet hole, described inclined-plane body of wall and one end of plane body of wall join and form L shaped structure, and on the metope of plane body of wall and inclined-plane body of wall, the slag lining that is positioned at steel outlet hole top is provided with the thickening layer that protrudes from metope.
Described plane body of wall and the junction of inclined-plane body of wall are arc transition.
The thickness of described thickening layer is 30mm.
beneficial effect
1, L shaped slag blocking wall structure of the present utility model can make molten steel flow field more stable, is conducive to the separated of slag and molten steel, has improved the cleanliness factor of molten steel simultaneously.
2, slag blocking wall of the present utility model is arcuate structure in the junction, turning of plane body of wall and inclined-plane body of wall, has effectively cut down eddy current to the washing away of this position, and has improved the whole erosion resistibility of slag blocking wall.
3, slag blocking wall of the present utility model arranges thickening layer at slag lining place, has effectively slowed down the erosion of molten steel to plane body of wall and inclined-plane body of wall, has improved the whole corrosion-resistant property of slag blocking wall.

Fig. 1 is the front view of the utility model structural representation; Fig. 2 is the top view of the utility model structural representation; Fig. 3 is along the sectional structure schematic diagram of A-A direction in Fig. 2; Fig. 4 is along the sectional structure schematic diagram of B-B direction in Fig. 2;
Reference numeral: 1, plane body of wall, 2, inclined-plane body of wall, 3, thickening layer, 4, steel outlet hole.
The specific embodiment
A kind of billet continuous casting tundish slag wall, comprise plane body of wall 1 and the inclined-plane body of wall 2 that is arranged on plane body of wall 1 one sides, on plane body of wall 1 and inclined-plane body of wall 2, be provided with steel outlet hole 4, described inclined-plane body of wall 2 joins and forms L shaped structure with one end of plane body of wall 1, and on the metope of plane body of wall 1 and inclined-plane body of wall 2, the slag lining that is positioned at steel outlet hole 4 tops is provided with the thickening layer 3 that protrudes from metope.Described plane body of wall 1 and the junction of inclined-plane body of wall 2 are arc transition.The thickness of described thickening layer 3 is 30mm.As shown in Figure 1, 2, the utility model in use, because plane body of wall 1, inclined-plane body of wall 2 connect into L shapedly, makes molten steel flow field in tundish stable, is conducive to the separated of slag and molten steel, has improved the cleanliness factor of molten steel.The curved structure in junction of plane body of wall 1 and inclined-plane body of wall 2, has effectively cut down eddy current to the washing away of this position, and has improved the whole erosion resistibility of slag blocking wall.As shown in Figure 3,4, the utility model, because the slag lining place at plane body of wall 1 and inclined-plane body of wall 2 is provided with thickening layer 3, has effectively slowed down the erosion of molten steel to plane body of wall 1 and inclined-plane body of wall 2, has improved the whole corrosion-resistant property of slag blocking wall.
