Abstract

The utility model provides a silicon carbide brick. The silicon carbide brick comprises a brick body; the brick body is in a shape of a hexahedron; a plurality of grooves are formed on at least one surface of the brick body; protruding parts are arranged on a surface opposite to the surface with the grooves; the plurality of grooves are discontinuously arrayed; the sections of the grooves or the protruding parts are arc-shaped or trapezoidal; when the grooves on one surface are arc-shaped, the protruding parts on the opposite surface are arc-shaped; and the arc-shaped grooves and the arc-shaped protruding parts on the opposite surfaces are identical in number, size, position and direction. Through the structure, by changing the shape of the silicon carbide brick, bricks are tightly connected when kilt furnaces and large saggers are built without using chamotte; not only the construction is simplified and the roasting period is shortened, but also the kilt furnaces and the large saggers are conveniently and quickly detached; and the silicon carbide bricks can be recycled, so the current requirements on resource conservation and environment friendliness are met.

Description

A kind of silicon carbide brick

Technical field

The utility model belongs to fire-resistive construction material technology field, is specifically related to a kind of silicon carbide brick.

Background technology

The thermal conductivity height of silicon carbide brick has good wearability, thermal shock resistance and erosion resisting.Can be used for internal lining of aluminium electrolytic bath, molten aluminum conduit and furnace kiln furnitures, big-and-middle-sized blast-furnace shaft bottom, furnace bosh and bosh, aluminium refining furnace furnace lining, zinc retort lining etc.Yet traditional cuboid silicon carbide brick is when building kiln and large-scale saggar by laying bricks or stones, need between brick and brick, smear and build chamotte by laying bricks or stones and could guarantee the tight of brickwork joint, thereby when causing kiln and large-scale saggar to toast before use, because of waiting for moisture content eliminating prolongation stoving time in the chamotte, and after kiln and the end of large-scale saggar military service phase, when needing to remove kiln and large-scale saggar, often because of building sintered compact between chamotte and the brick by laying bricks or stones, cause and build the brick body by laying bricks or stones and be difficult to remove, to such an extent as in demolishing process, will originally can destroy by reusable silicon carbide brick.Be difficult to satisfy the requirements such as clean environment firendly that present people advocate.

The utility model content

The purpose of this utility model is to provide a kind of can solve above work progress complexity, and stoving time is long, is difficult to the silicon carbide brick of problems such as recycling.

A kind of silicon carbide brick described in the utility model, it comprises the brick body, and described brick body is a hexahedron, and wherein at least one face is provided with groove, preferable scheme is for to be equipped with groove on three of the brick body adjacent in twos faces, the face relative with the face that is provided with groove is provided with protuberance.

Described groove is a plurality of, and a plurality of grooves are intermittently arranged.

Described groove and protuberance section are arc or trapezoidal.

If be arc groove on one of them face, be exactly the arc protuberance on the then relative face with it, the arc groove on every pair of opposite face on the brick body and quantity, size and the orientation of arc protuberance are identical.

After the utility model adopts said structure, by changing the contour structures of silicon carbide brick, when building kiln and large-scale saggar by laying bricks or stones, be connected between brick and the brick and closely and not need to build by laying bricks or stones chamotte, not only simplified construction, shortened baking cycle, and it is also convenient and swift when removing kiln and large-scale saggar, realized the recycle and reuse of silicon carbide brick simultaneously, met current society and advocate and economize on resources, and the requirement of environmental protection and energy saving.

Description of drawings

Fig. 1 is the structural representation of a kind of silicon carbide brick of the utility model.

Among the figure, 1-brick body, 2-face, 3-groove, 4-protuberance.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As shown in Figure 1, a kind of silicon carbide brick, it comprises brick body 1, and described brick body 1 is a hexahedron, and wherein at least one face 2 is provided with groove 3, and its opposite is provided with protuberance 4.

Described groove 3 is a plurality of, and a plurality of grooves 3 are intermittently arranged.

The section of described groove 3 and protuberance 4 is an arc or trapezoidal.

When being arc groove 3 on one of them face, be exactly arc protuberance 4 on the then relative another side with it, the arc groove 3 on the opposite face and quantity, size and the orientation of arc protuberance 4 are identical.

When using a kind of silicon carbide brick of the present utility model to build kiln or large-scale saggar by laying bricks or stones, use is equipped with the silicon carbide brick of arc groove 3 on three of brick body 1 adjacent in twos faces, being provided with one of arc groove 3 faces down, its top is arc protuberance 4, its left side is the arc groove 3 of side, its the right is a corresponding side arc protuberance 4, second brick built by laying bricks or stones on the right side of first same horizontal direction of brick, its direction unanimity, 3 arc protuberances 4 with the side of first brick of the arc groove of the side of second brick are closely pegged graft, all the other silicon carbide bricks also are arranged in order, and form firm body of wall basis.

When body of wall needed 90 degree corners, the brick that changes another direction over to need insert the side arc groove 3 of angle position brick body 1 with arc protuberance 4, reaches the corner effect.

When brick build finish first annular after, then build last layer by laying bricks or stones, the direction of brick is constant, the silicon carbide brick of the second layer is because will avoid the generation of straight joint, the opposing horizontal loading, increase integral rigidity, improve the stability of wall body structure, the arrangement so misplace, simultaneously, because be continuously arranged cross type at the arc protuberance 4 on the brick top at turning, so, the bottom surface arc groove 3 of the silicon carbide brick of the second layer can misplace arrange after, still can closely cooperate with the brick of ground floor, continuous like this repeat to reach build height by laying bricks or stones.

Fitting tight between the brick body of the present utility model and do not need to build by laying bricks or stones chamotte or mortar, rely on its groove 3 and protuberance 4 to peg graft fully, avoid the slit that produces because thermal coefficient of expansion differs, increased safety coefficient, also be convenient to simultaneously remove and recycle and reuse.

Above-mentioned embodiment is a preferred embodiment of the present utility model; it is not the scope that is used for limiting enforcement of the present utility model and claim; all equivalences of making according to the described content of the utility model patent application protection domain change and modify, and all should be included in the scope of the utility model patent application.
