CN202139272U - Brick used for top of tuyere of blast furnace - Google Patents

Abstract

The utility model discloses a brick used for the top of the tuyere of a blast furnace. The brick transversely penetrates the top or the bottom of the tuyere; the cross section of the brick adopts a structure taking the shape similar to an isosceles trapezoid; the upper surface and two side surfaces of the brick used for the top are rectangular plane surfaces; the two end surfaces of the brick are plane surfaces; and the upper surface of the brick is wider than the lower surface thereof and is a concave cambered surface. The brick used for the top of the tuyere has a simple and regular structure, is easy to splice and combine, is favorable for implementation, and helps to increase the construction speed; the brick can be formed through machine moulding, the quality is stable, and the efficiency is high, so that the economical effects of lowering the manufacturing cost, being convenient for field masonry and improving the service life can be achieved; besides, the inner and the outer surfaces of a built tuyere are plane surfaces, so that the inner and the outer surfaces of the tuyere are plane surface, then the edge of the tuyere can be processed conveniently, a ring-shaped groove can be formed on the edge of the tuyere easily, and plugging and sealing are facilitated.

Description

The blast-furnace tuyere top 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 top 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 top brick to the deficiency of at present existing situation.

The technical scheme that the utility model adopted: a kind of blast-furnace tuyere top brick; Laterally through top, air port or bottom; Its xsect is approximate isosceles trapezoidal structure, and the upper surface of this top brick and two sides are rectangle plane, and both ends of the surface are the plane; The width of upper surface is greater than the lower surface width, and lower surface is a cancave cambered surface.

Lower 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:

Fig. 1 is the front schematic view in blast-furnace tuyere zone;

Fig. 2 is the perspective view of the utility model brick type;

Fig. 3 is that the A of Fig. 2 is to structural representation;

Fig. 4 is the side structure synoptic diagram of Fig. 2.

Label 1 and 1 ' is an end face among the figure, and 2 is upper surface, and 3 is the side, and 4 is arc groove, and 5 is lower surface, and 6 is the blast-furnace tuyere top brick.

Embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of blast-furnace tuyere top brick is applicable in the regular polygon blast-furnace tuyere structure, because the inside and outside surface in zone, air port is the plane, is rectangle so the brick type is positioned at the upper surface 2 in air port, and both ends of the surface 1 and 1 ' are the plane.This brick is laterally through top, air port, and its xsect is approximate isosceles trapezoidal structure, and its two sides also are rectangle plane 3.In addition, the width of upper surface 2 is greater than the lower surface width, and lower surface is a cancave cambered surface.Lower surface 4 is provided with arc groove with end face 1 intersection wherein.The internal surface of arc groove 4 is a cancave cambered surface.

Claims (3)

1. blast-furnace tuyere top brick; It is characterized in that: laterally through top, air port or bottom; Its xsect is approximate isosceles trapezoidal structure, and the upper surface of this top brick and two sides are rectangle plane, and both ends of the surface are the plane; The width of upper surface is greater than the lower surface width, and lower surface is a cancave cambered surface.

2. blast-furnace tuyere top brick according to claim 1 is characterized in that: lower surface and one of them end face intersection are provided with arc groove.
