Description

Large-scale pouring cordierite furnace door brick structure

Technical Field

The utility model belongs to the technical field of refractory material, especially, relate to a large-scale pouring cordierite furnace door brick structure.

Background

The service life of the furnace door lining brick of the coking coke oven in steel and iron enterprises and coking industry is short due to long-term thermal shock, chemical corrosion and mechanical impact, so the furnace door brick glazed brick with high quality has stronger thermal shock stability, permeation resistance, corrosion resistance and carbon deposition resistance, and has energy-saving and environmental-friendly effects. In recent years, glazed tiles of cast furnace door tiles have gradually spread over the domestic market. The inventor has been in continuous production of glazed tiles of the furnace door tiles for more than 10 years, and the users have fed back a good comment, but the tiles are still vulnerable, particularly the joints of the extending surfaces and the separating surfaces of the furnace door tiles are damaged most seriously.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims to solve the problem that the joint of the extending surface and the separating surface of the existing furnace door brick is easy to be damaged.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a large-scale pouring cordierite furnace door brick structure, includes furnace door brick body, furnace door brick is close to arbitrary one end along its length direction and has the face of extending of thickness attenuate, and there is the parting plane that sets up along furnace door brick body thickness direction between the face of extending of attenuate and the furnace door brick body of normal thickness, and the face of extending of attenuate is from the parting plane and the tip that extends the face of the combination department orientation of extending the face, and the thickness of furnace door brick body further reduces, and furnace door brick structure still includes the cube that obtains along the width direction translation with the buffering face that improves furnace door brick parting plane and extend the thickness of face combination department as the buffer layer.

Adopt the buffer layer of buffer face translation formation for the thickness of the junction of furnace door brick parting surface and extension face increases, does not influence holistic structure simultaneously as far as possible, makes on the basis of keeping original characteristic, improves holistic life.

Furthermore, the buffering face is triangular, the length of the separation face along the thickness direction of the furnace door brick body and the length of the extension face along the length direction of the furnace door brick body are respectively used as two sides of the triangle, and the translation distance of the triangle is smaller than the width of the furnace door brick body.

The design similar to that of a bracket is adopted, so that the bracket, the separating surface and the extending surface form a triangular groove structure, the stress area of the position is increased, the stress of the material in the working process is reduced, and the stability of the joint is greatly improved.

Furthermore, in the buffering face, the length of the separating face along the thickness direction of the furnace door brick body and the length of the extending face along the length direction of the furnace door brick body are respectively used as two edges of the buffering face, the two ends of the two edges which are farthest away form a curved surface recess facing the furnace door brick body, and the translation distance of the buffering face is equal to the width of the furnace door brick body.

The structure of the curved surface is adopted, and the stress applied in the working process is dispersed by improving the thickness of the joint part so as to realize the increase of the structural strength.

Further, the junction of the separating surface and the normal thickness of the furnace door brick body forms a curved surface.

Further, the bracket structure formed by the triangular translation is arranged in the middle of the furnace door brick body in the width direction.

Has the advantages that: compared with the prior art, the utility model has following positive effect:

adopt the utility model discloses a design for the stress of extension face and parting surface joint is alleviated, is shared by the structure that increases, has improved the holistic structural strength of the brick body.

FIG. 1 is a schematic diagram of a prior art structure;

fig. 2 is a schematic structural diagram of embodiment 1 of the present invention;

fig. 3 is a schematic structural diagram of embodiment 2 of the present invention.

Detailed Description

The invention is further described with reference to specific embodiments without limiting its scope.

Example 1

As shown in FIG. 1 and FIG. 2, a large-scale pouring cordierite furnace door brick structure, including furnace door brick body 1, furnace door brick 1 is close to arbitrary one end along its length direction and has the face 2 that extends of thickness attenuate, there is the parting plane 3 that sets up along furnace door brick body thickness direction between the face 2 that extends of attenuate and the furnace door brick body 1 of normal thickness, the face 2 that extends of attenuate is from parting plane 3 and the tip of extending the face 2 of junction orientation of face 2, the thickness of furnace door brick body 1 further reduces, furnace door brick 1 structure still includes and follows the cube that the width direction translation obtained with the buffering face that improves the thickness of furnace door brick 1 parting plane 3 and the face 2 junction of extending as the buffer layer.

The buffering face is triangle-shaped, and the length of separating face 3 along door brick body thickness direction and the length of extending face 2 along door brick body length direction are regarded as two limits of triangle-shaped respectively, and the distance of triangle-shaped translation is less than the width of door brick body.
