Abstract

The invention relates to the field of fireproof components, in particular to a novel mullite brick. The novel mullite brick comprises a basic body and is characterized in that the basic body is a cube with groove strips and protruding strips, the four protruding strips are arranged on the upper surface of the basic body, the four groove strips are arranged at the positions, corresponding to the protruding strips on the upper surface, of the lower surface, and bricks are assembled together through the protruding strips and the groove strips. The left and right surfaces of the basic body are planes, and four equal and square through holes are formed in the front and back surfaces of the basic body. The novel mullite brick is used for replacing a high-alumina brick or a clay brick, has the advantages of being high in refractoriness under load, strength and thermal shock resistance and the like, is a novel anti-stripping abrasion-resistant fireproof material and facilitates long-time stable work of a lime kiln.

Description

A kind of Novel mullite brick

Technical field

The present invention relates to refractory part field, be specially a kind of Novel mullite brick.

Background technology

Along with developing rapidly of smelting iron and steel, Large Lime kiln is (telescopic, wheat Wurz series) arise at the historic moment, and general high-alumina brick or clay brick have been not suitable for and have employed on limekiln, particularly the thermal shock resistance of clay brick and general high-alumina brick is poor, in use easily there is large-area peeling phenomenon, thus affect service life, the present invention's Novel mullite brick replaces high-alumina brick or clay brick, mullite brick has high RUL, the advantage such as high strength and high thermal shock resistance, it is a kind of novel anti-strip wearing-proof refractory material, be conducive to the long-term stable operation in limekiln.

Summary of the invention

The object of the invention is to for the thermal shock resistance of pointed clay brick and general high-alumina brick in background technology poor, in use easily there is large-area peeling phenomenon, thus affect service life, a kind of Novel mullite brick that can solve foregoing problems is provided.

For realizing object of the present invention, there is provided following technical scheme: a kind of Novel mullite brick, comprise matrix, it is characterized in that described matrix is the cube with slot stick and raised line, described body upper surface is provided with large raised line such as 4 grades, and lower surface has for the position of upper surface raised line the slot stick that 4 grades are large, is assembled together between fragment of brick by raised line and slot stick, about matrix, surface is plane, and front and rear surfaces is provided with large square through-hole such as 4 grades.

As preferably, the length of the square through-hole of described Novel mullite brick is 1/4 of brick body length.

As preferably, the raised line of described Novel mullite brick and slot stick can be square, trapezoidal, triangles, and raised line and slot stick shape match, and are spliced between fragment of brick by raised line and slot stick.

As preferably, the large square through-hole inner surface such as 4 grades of described Novel mullite brick all scribbles heat insulating coat.

Beneficial effect of the present invention: the thermal shock resistance that instant invention overcomes clay brick and general high-alumina brick is poor, in use easily there is large-area peeling phenomenon, thus affect the shortcomings such as service life, provide a kind of Novel mullite brick, comprise matrix, it is characterized in that described matrix is the cube with slot stick and raised line, described body upper surface is provided with large raised line such as 4 grades, lower surface has for the position of upper surface raised line the slot stick that 4 grades are large, be assembled together by raised line and slot stick between fragment of brick, make the combination of fragment of brick and fragment of brick more firm, about matrix, surface is plane, front and rear surfaces is provided with large square through-hole such as 4 grades, arranging through hole makes mullite brick own wt alleviate, Novel mullite brick have employed the making of new material and new technology, in sintering procedure, raising is burnt till stable, the compressive resistance of corresponding like this raising finished product and refractoriness under load, suitably add additive in addition to improve its thermal shock resistance to improve the resistance to flaking of finished product, key position in limekiln uses mullite brick, make increase substantially 50% the service life in limekiln like this, accordingly also 50% is reduced to the loss of refractory material.

Accompanying drawing explanation

Fig. 1 is mullite brick structural representation.

In figure, 1 is matrix, and 1.1 is raised line, and 1.2 is slot stick, and 1.3 is square through-hole.

Detailed description of the invention

The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.

Embodiment 1: Fig. 1 is mullite brick structural representation, a kind of Novel mullite brick, comprise matrix 1, it is characterized in that described matrix 1 is with the cube of slot stick 1.2 with raised line 1.1, described matrix 1 upper surface is provided with large raised line 1.1 such as 4 grades, lower surface has for the position of upper surface raised line the slot stick 1.2 that 4 grades are large, about matrix, surface is plane, front and rear surfaces is provided with large square through-hole 1.3 such as 4 grades, the length of square through-hole 1.3 is 1/4 of brick body length, raised line 1.1 and slot stick 1.2 can be squares, trapezoidal, triangle, raised line 1.1 and slot stick 1.2 shape match, spliced by raised line and slot stick between fragment of brick, 4 large square through-hole inner surfaces such as grade all scribble heat insulating coat.

The present invention is not limited to the mullite brick involved by above-mentioned detailed description of the invention, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the present invention or similar change all should be encompassed in the scope of the claims in the present invention.
