Abstract
The utility model discloses an improved ladle cover for middle ladles, which comprises a ladle cover substrate, the upper part of the substrate is provided with an arc arch surface, the lower part of the substrate is provided with a rectangular body, a sealing steel plate is arranged between the arc arch surface and the rectangular body and divides the substrate into an upper layer and a lower layer, the upper layer is a thermal insulation layer, the lower layer is a refractory material layer, the bottom surface of the sealing steel plate is provided with a plurality of inverted Y-shaped supports, and a refractory material is poured and filled in the refractory material layer. Through the setting, the ladle cover for middle ladles is long in service life and low in cost, and can achieve an effect of reutilization; and the thermal insulation effect of middle ladles is remarkable.
Description
Technical field
The utility model belongs to steel-making refractory material container and makes the field, relates 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 utility model provides a kind of high temperature deformation that prevents, the improved tundish clad that can repeatedly utilize to the deficiency of prior art.
The utility model 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.
Further preferred as the utility model, " Y " shape support that falls is preferably 8-12.
For better explaining the technical scheme of the utility model; Introduce the operation principle of the utility model once in detail: when the tundish clad with the utility model carried out capping to middle cover, refractory material oil effectively prevented collapsing of fire proofed wood in being cast in down between " Y " shape support; 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, prevented that clad is owing to excessive deformation ruptures; When the refractory material inefficacy needs to change; Can be again lower floor's refractory masses pouring fireproof material again, realize recycling, prolong the service life of clad.
The beneficial effect of the utility model: long service life, cost is low, can realize recycling, and the heat insulation effect of tundish is remarkable.
