Abstract
The present invention relates to refractory part field, be specially a kind of silicon nitride bonded silicon aluminum silicon carbide brick, comprise matrix, it is characterized in that described matrix is made up of brick seat and brick pipe, brick seat is cross section is foursquare cuboid, and brick pipe is cylinder, brick seat inside is divided into three, left, center, right part, left part and right part are "the" shape cavity, and middle part is cavity body, bottom brick seat and brick pipe upper surface be the loading end of not perforate.Use silicon nitride bonded silicon aluminum silicon carbide brick of the present invention to replace aluminium siliceous mullite brick, silicon nitride bonded silicon aluminum silicon carbide brick has high abrasion and excellent heat-resistant knocking stability, and its service life improves more than 40% than traditional siliceous mullite brick.
Description
Technical field
The present invention relates to refractory part field, be specially a kind of silicon nitride bonded silicon aluminum silicon carbide brick.
Background technology
Along with cement rotary kiln progressively maximizes, traditional aluminum silicon carbide brick can not adapt to its instructions for use, each cement plant also proposes the requirement of more increasing accordingly to preheating zone siliceous mullite brick, particularly it is also proposed harsher requirement to the thermal shock resistance of product and wearability.The present invention's silicon nitride bonded silicon aluminum silicon carbide brick replaces siliceous mullite brick, and silicon nitride bonded silicon aluminum silicon carbide brick has high abrasion and excellent heat-resistant knocking stability, and its service life improves more than 40% than traditional siliceous mullite brick.
Summary of the invention
The thermal shock resistance that the object of the invention is to for siliceous mullite brick pointed in background technology is poor, in use easily there is large-area peeling phenomenon, thus affect service life, a kind of silicon nitride bonded silicon aluminum silicon carbide brick that can solve foregoing problems is provided.
For realizing object of the present invention, there is provided following technical scheme: a kind of silicon nitride bonded silicon aluminum silicon carbide brick, comprise matrix, it is characterized in that described matrix is made up of brick seat and brick pipe, brick seat is cross section is foursquare cuboid, and brick pipe is cylinder, brick seat inside is divided into three, left, center, right part, left part and right part are "the" shape cavity, and middle part is cavity body, bottom brick seat and brick pipe upper surface be the loading end of not perforate.
As preferably, the length of three parts in the inner left, center, right of described brick seat is identical.
As preferably, the external diameter of described cylinder brick pipe is identical with brick seat length, and internal diameter is identical with the central cavity body length of brick seat inside.
As preferably, the height of described cylinder brick pipe is 1/2 of brick seat height.
As preferably, the central cavity body of described brick seat inside communicates with brick pipe.
Beneficial effect of the present invention: the thermal shock resistance that instant invention overcomes siliceous mullite brick is poor, in use easily there is large-area peeling phenomenon, thus affect the shortcomings such as service life, provide a kind of silicon nitride bonded silicon aluminum silicon carbide brick, comprise matrix, it is characterized in that described matrix is made up of brick seat and brick pipe, brick seat is cross section is foursquare cuboid, brick pipe is cylinder, brick seat inside is divided into a left side, in, right three parts, left part and right part are "the" shape cavity, middle part is cavity body, bottom brick seat and brick pipe upper surface be the loading end of not perforate."the" shape cavity is set and cavity body makes silicon nitride bonded silicon aluminum silicon carbide brick own wt alleviate, silicon nitride bonded silicon aluminum silicon carbide brick have employed the making of new material and new technology, with salic 90% high grade bauxite and one-level fused white corundum in sintering procedure, because it has less glassy phase, next selects 97% carborundum, it has higher wearability, the appropriate silicon nitride of another interpolation and metallic silicon, thus improves high-temperature behavior and the thermal shock resistance of product.
Accompanying drawing explanation
Fig. 1 is silicon nitride bonded silicon aluminum silicon carbide brick front view.
In figure, 1 is brick seat, and 2 is brick pipe, and 1.1 is left cavity, and 1.2 is middle part cavity, and 1.3 is right cavity.
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 silicon nitride bonded silicon aluminum silicon carbide brick front view, a kind of silicon nitride bonded silicon aluminum silicon carbide brick, comprise matrix, it is characterized in that described matrix is made up of brick seat 1 and brick pipe 2, brick seat 1 for cross section be foursquare cuboid, brick pipe 2 is cylinder, brick seat inside is divided into left cavity 1.1, middle part cavity 1.2, right cavity 1.3 3 parts, left cavity 1.1 is "the" shape cavity with right cavity 1.3, middle part cavity 1.2 is cavity body, bottom brick seat 1 and brick pipe 2 upper surface be the loading end of not perforate, the inner left cavity 1.1 of brick seat, middle part cavity 1.2, the length of right cavity 1.3 3 parts is identical, the external diameter of brick pipe 2 is identical with brick seat 1 length, internal diameter is identical with middle part cavity 1.2 length of brick seat 1 inside, the height of brick pipe 2 is 1/2 of brick seat 1 height, the middle part cavity 1.2 of brick seat 1 inside communicates with brick pipe 2.
The present invention is not limited to the silicon nitride bonded silicon aluminum silicon carbide brick involved by above-mentioned detailed description of the invention, 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.
