Abstract
The invention discloses an improved tundish cover comprising a tundish cover body, wherein an arced surface is arranged on the upper part of the body, a rectangular body is arranged on the lower part of the body, a sealing steel plate is arranged between the circular arc-shaped arched surface and the rectangular body to divide the body into an upper layer and a lower layer, the upper layer is an insulation isolating layer, the lower layer is a refractory material layer, a plurality of inverted Y-shaped brackets are arranged on the bottom surface of the sealing steel plate, and a refractory material is poured in the refractory material layer. By means of the arrangement, the tundish ladle cover has long service life and low cost, the tundish ladle cover can be repeatedly used, and the insulation effect of the tundish is excellent.
Description
Technical field
The invention belongs to steel-making refractory material container and make the field, relate in particular to a kind of improved tundish clad.
Background technology
Tundish is as the most frequently used a kind of refractory material container of field of steel-making, and molten steel flows in a plurality of tundish from big ladle branch, in order to prevent the thermal loss of molten steel in the tundish; Air pollution that causes with molten steel and toxic gas are to workman's injury, and generally all tundish is provided with clad, existing on the market mostly clad be plate; Easy deformation under the high-temperature baking of molten steel, thus cause inner refractory material to come off, fall into molten steel; Cause molten steel to splash or explode and cause unnecessary accident; And be difficult to after refractory material comes off repair, shortened the service life of tundish greatly, have much room for improvement.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of high temperature deformation that prevents is provided, the improved tundish clad that can repeatedly utilize.
The present invention provides following technical scheme for solving the problems of the technologies described above: a kind of improved tundish clad comprises the clad matrix; It is characterized in that matrix top is the circular arc arch face, the bottom is a cuboid, is provided with the sealing steel plate between circular arc arch face and cuboid and matrix is separated into two-layer up and down; The upper strata is an insulating interlayer; Lower floor is a refractory masses, and sealing steel plate bottom surface is provided with several " Y " shape supports, and refractory material casting is filled out and is overlying in the refractory masses.
As of the present invention further preferred, " Y " shape support that falls is preferably 8-12.
For better explaining technical scheme of the present invention, introduce operation principle of the present invention once in detail: when with tundish clad of the present invention middle cover being carried out capping, refractory material oil is in being cast in down between " Y " shape support; Effectively prevent collapsing of fire proofed wood, prevent effectively that through end face and the insulating interlayer that the sealing steel plate constitutes heat from directly conducting on the clad end face, and because end face is the circular arc arch; Increased the distortion allowance of clad greatly; Prevent clad owing to excessive deformation ruptures, when the refractory material inefficacy need to be changed, can be again lower floor's refractory masses pouring fireproof material again; Realize recycling, prolong the service life of clad.
Beneficial effect of the present invention: long service life, cost is low, can realize recycling, and the heat insulation effect of tundish is remarkable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of improved tundish clad comprises clad matrix 1, it is characterized in that matrix 1 top is the circular arc arch face; The bottom is a cuboid, is provided with sealing steel plate 2 between circular arc arch face and cuboid and matrix is separated into two-layer up and down, and the upper strata is an insulating interlayer 3; Lower floor is a refractory masses 4; Sealing steel plate 2 bottom surfaces are provided with several " Y " shape supports 5, and refractory material 6 cast are filled out and are overlying in the refractory masses 4, and " Y " shape support 5 that falls is 8-12.
Claims (2)
1. an improved tundish clad comprises the clad matrix, it is characterized in that matrix top is the circular arc arch face; The bottom is a cuboid; Be provided with the sealing steel plate between circular arc arch face and cuboid and matrix be separated into two-layer up and down, the upper strata is an insulating interlayer, and lower floor is a refractory masses; Sealing steel plate bottom surface is provided with several " Y " shape supports, and refractory material casting is filled out and is overlying in the refractory masses.
