CN202139248U - Brick for tuyere side of blast furnace - Google Patents

Abstract

The utility model discloses a brick for the tuyere side of a blast furnace, which horizontally penetrates through portions of the left side and the right side of a tuyere and is similarly in a cuboid structure. The upper surface and the lower surface of the brick are in rectangular shapes and parallel to each other, the front end face, the rear end face and the left lateral face of the brick are in rectangular shapes and parallel to each other, and the right lateral face is in a concave arc shape. The brick for the tuyere side of the blast furnace is simple and regular in structure, easy to put together and combine, convenient to construct and high in construction speed. The brick for the tuyere side of the blast furnace can be formed by mechanical pressing and is stable in quality and high in efficiency, thereby achieving economic effects of reducing production cost, bringing convenience to on-site building and prolonging service life. The inner surface and the outer surface of the built tuyere are planes, thereby facilitating edge processing of the tuyere. The outer edge of the tuyere is easy to be provided with annular grooves, thereby bringing convenience to plugging and sealing.

Description

The blast-furnace tuyere side is used brick

Technical field:

The utility model relates to the improvement technology in high end furnace air port, is specifically related to a kind of blast-furnace tuyere side and uses brick.

Background technology:

At present, high end furnace mostly adopts cirque structure, and this structure is to be different from common planar to build by laying bricks or stones building by laying bricks or stones; It is big to build difficulty by laying bricks or stones; Because air port zone inside liner arc surface, the brick type of modular tile of press the arc surface design is quite complicated, to all strictnesses of requirement of brick type and brickwork joint coating.Local even need manual ramming, perhaps cast, vibrating forming, this conventional design method makes troubles to production, difficult quality control, yield rate is low, and difficulty is built at the scene by laying bricks or stones.Especially the setting in sidewall air port, the air port, side of annular further strengthen the difficulty of building by laying bricks or stones, occur the situation of doing over again easily, influence the whole construction progress.

The utility model content:

The utility model proposes a kind of blast-furnace tuyere side and uses brick the deficiency of at present existing situation.

The technical scheme that the utility model adopted: a kind of blast-furnace tuyere side is used brick; Laterally the and arranged on left and right sides position through the air port is approximate rectangular structure, and its upper and lower surface is parallel rectangle; The front and rear end is parallel rectangle with left surface, and right flank is a cancave cambered surface shape.

Cancave cambered surface and one of them end face intersection are provided with arc groove.

The internal surface of arc groove is a cancave cambered surface.

The useful positively effect of the utility model:

1, the utility model air port top brick is simple in structure and regular, pieces together combination easily, is beneficial to enforcement, and speed of application is fast.Can mechanical pressing, steady quality, efficient is high, reduces production costs thereby obtain, and build by laying bricks or stones at the scene of being convenient to, and improves the economical effectiveness in work-ing life.

2, because the inside and outside surface in the air port after building by laying bricks or stones is the plane, so the inside and outside surface in air port is the plane also, be convenient to edge, air port processing treatment, the air port outer rim is provided with annular recesses easily, helps shutoff and sealing.

Description of drawings:

Label 1 is an end face among the figure, and 2 is upper surface, and 3 is cancave cambered surface, and 4 is arc groove, and 5 use brick for the blast-furnace tuyere side.

Embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4; Horizontal and arranged on left and right sides position when this blast-furnace tuyere side is used with brick through the air port, its structure is approximate rectangular parallelepiped, its upper surface 1 is parallel rectangle with lower surface; Front and rear end 2 is parallel rectangle with left surface; Right flank is a cancave cambered surface shape 3, and this cancave cambered surface 3 is provided with arc groove 4 with end face 2 intersections wherein, and the internal surface of arc groove 4 is a cancave cambered surface.

Claims (3)

1. a blast-furnace tuyere side is used brick, it is characterized in that: the horizontal and arranged on left and right sides position through the air port is approximate rectangular structure, and its upper and lower surface is parallel rectangle, and the front and rear end is parallel rectangle with left surface, and right flank is a cancave cambered surface shape.

2. blast-furnace tuyere side according to claim 1 is used brick, it is characterized in that: cancave cambered surface and one of them end face intersection are provided with arc groove.

3. blast-furnace tuyere side according to claim 2 is used brick, it is characterized in that: the internal surface of arc groove is a cancave cambered surface.
