Abstract

The utility model discloses an easy-to-recycle silicon carbide brick. The silicon carbide brick comprises a brick body with a trapezium-shaped section, wherein the brick body is a hexahedron consisting of an inner face, an outer face, two sides and two big faces; a groove is formed on one side, and a bulge is correspondingly formed on the other side; crossed grooves are formed on one big face, and one of the grooves is perpendicular to the inner face and the outer face; crossed bulges are correspondingly formed on the other big face, and one of the bulges is perpendicular to the inner face and the outer face; and a notch groove is formed at the intersecting part of the big face with the grooves and the side with the groove. According to the silicon carbide brick provided by the utility model, by changing the outline structure of a conventional silicon carbide brick, during building a kiln or a large-scale sagger, the connection among brick bodies are compact, so that no or a little amount of building masonry fire clay is required, accordingly, the construction is simplified and the baking period is shortened, while the dismantling of the kiln and the large-scale sagger is convenient and fast, and recycling of the silicon carbide brick is realized.

Description

The silicon carbide brick that is easy to reclaim

Technical field

The utility model relates to a kind of fire-resistant heat insulating material, relates to specifically a kind of silicon carbide brick that is easy to reclaim.

Background technology

The thermal conductivity of existing silicon carbide brick is high, and good wearability, thermal shock resistance and erosion resisting are arranged.Can be used for internal lining of aluminium electrolytic bath, molten aluminum conduit and furnace with 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 to smear between brick and brick and build the tight of chamotte guarantee brickwork joint by laying bricks or stones, thereby when causing kiln and large-scale saggar to toast before use, because waiting for that the moisture content eliminating in chamotte extends stoving time, and after kiln and the end of large-scale saggar military service phase, when needing to remove kiln and large-scale saggar, often because building sintered compact between chamotte and 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 to will originally can destroy by reusable silicon carbide brick in demolishing process.

Summary of the invention

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of silicon carbide brick that is easy to reclaim, and this brick can be simplified work progress, reduces stoving time, and recycling also more for convenience.

To achieve these goals, the technical solution adopted in the utility model is: a kind of silicon carbide brick that is easy to reclaim, comprise that the cross section is trapezoidal brick body, and described brick body is by a inside, an outside, two sides and two hexahedrons that large face forms; Be provided with groove on a side, correspondence is provided with projection on the another side; Be provided with the groove that intersects in length and breadth on a large face, one bar groove and within and without are perpendicular, and be positioned in the middle part of the outer of the inside and outside, the corresponding projection that intersects in length and breadth that is provided with on another large, one bar projection is perpendicular with within and without, and is positioned at the middle part, outer of the inside and outside; Offer short slot establishing reeded large the intersection with the side.

Preferably, the section of described groove and projection is curved or trapezoidal.

Preferably, described short slot and projection are complementary.

Compared with prior art, the beneficial effects of the utility model are: silicon carbide brick of the present utility model, by changing the contour structures of silicon carbide brick, when building kiln and large-scale saggar by laying bricks or stones, being connected between brick body and brick body closely and not needs to build by laying bricks or stones chamotte or has not only simplified construction with building chamotte by laying bricks or stones less, has shortened baking cycle, and also convenient and swift when removing kiln and large-scale saggar, realized simultaneously the recycle and reuse of silicon carbide brick.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1 and Fig. 2, the silicon carbide brick that is easy to reclaim of the present utility model comprises that the cross section is trapezoidal brick body 1, and described brick body 1 is by a inside 11, an outside, two sides 12 and two hexahedrons that large face 13 forms; Be provided with groove 2 on a side 12, correspondence is provided with projection 3 on another side 12; Be provided with the groove 2 that intersects in length and breadth on a large face 13, one bar groove 2 is perpendicular with the inside 11 and outside, and be positioned in the middle part of the outer of the inside 11 and outside, the corresponding projection 3 that intersects in length and breadth that is provided with on another large 13, one bar projection 3 is perpendicular with the inside 11 and outside, and is positioned at the middle part, outer of the inside 11 and outside; Offer short slot 4 at the large face 13 that is provided with groove 2 and the intersection of side 12.The section of described groove 2 and projection 3 is curved.Described short slot 4 is complementary with projection 3.

During use, this silicon carbide brick fissure of displacement is built by laying bricks or stones, in building by laying bricks or stones, closely and not needs to build by laying bricks or stones chamotte or few with building chamotte by laying bricks or stones owing to connecting between brick body 1, its large 13 short slot 4 with 12 intersections, side, just with face 13 greatly on the tight joint close of projection 3; Also convenient and swift when removing kiln and large-scale saggar, realized the recycle and reuse of silicon carbide brick.

Above-mentioned is only a kind of embodiment of the present utility model; not in order to limit the utility model; those skilled in the art can make various changes and improve said structure; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
