Abstract
The utility model discloses a special perforated precast brick for the air deflecting wall of a shaft furnace. The special perforated precast brick for the air deflecting wall of the shaft furnace comprises a brick body which is rectangular, a through hole is formed between two large surfaces of the brick body, and the through hole is positioned in the centers of the large surfaces; a rectangular bulge is formed on one end surface of the two end surfaces of the brick body in the length direction, a rectangular groove is formed on the other end surface and in a position corresponding to the rectangular bulge, and the rectangular bulge are perpendicular to the two large surfaces; and bulges are symmetrically formed on one large surfaces of the brick body in the length direction, and grooves are formed on the other large surface in the length direction and in positions corresponding to the bulges. The constructed air deflecting wall of the shaft furnace is firm, the stability is excellent, the weight is light, the service life of the air deflecting wall is prolonged, and the service life of the air deflecting wall reaches more than two years at least. The furnace shutdown time of the shaft furnace is reduced, more than 10 thousand tons of pellets can be produced each year, and the production efficiency and the economic benefits of the shaft furnace are improved.
Description
Technical field
The utility model relates to a kind of fire-resistant heat insulating material, relates to specifically the special-purpose preformed bricks with holes of a kind of air guide wall for vetical furnace.
Background technology
At present, the air-guiding wall in iron and steel metallurgy system Shaft Furnace Pelletizing Process all adopts standard refractory brick to pile up to form at home, and its life-span of this air-guiding wall is shorter, also all is no more than the longest service life about a year and a half, and its life-span is basic termination just also.Its main cause is that after air-guiding wall is subjected to high temperature, the oxidative attack of wind brush, because air-guiding wall load is too large, deflection deformation, displacement and circulation are not smooth, cause its life-span to terminate fast.Palletizing shaft furnace is changed an air-guiding wall just needs the time in a nearly week of stopping production, economic loss nearly 1,000,000.This has a strong impact on the operating rate of palletizing shaft furnace, the raising of restriction labor productivity, economic benefit.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the special-purpose preformed bricks with holes of a kind of air guide wall for vetical furnace, and this brick structure is simple, is easy to make,, good stability lightweight with its air guide wall for vetical furnace of building by laying bricks or stones, long service life.
To achieve these goals, the technical solution adopted in the utility model is: the special-purpose preformed bricks with holes of a kind of air guide wall for vetical furnace, comprise the brick body, and described brick body is rectangular, is provided with through hole between two large faces of brick body, and it is central that through hole is positioned at large face; On brick body both ends of the surface along the length direction, one end is provided with rectangular preiection, and the other end is provided with rectangular recess to the reply rectangular preiection, and rectangular preiection and two large faces are perpendicular; Be provided with the air-flow short slot on brick body two sides along the length direction, short slot is positioned at middle part, side and perpendicular with two large faces; Four corner angle sections of intersecting in the end face of brick body and side are provided with flat chamfering; A large face at the brick body is arranged with projection along the length direction, and another large face is provided with groove to tackling projection along the length direction.
Preferably, the cross section of described air-flow short slot is isosceles triangle, and drift angle is 90 degree.
Further, the area of plane of described flat chamfering is half of air-flow short slot area.
Further, described projection is two or more, and quantity can not be odd number.
Compared with prior art, the beneficial effects of the utility model are: the air guide wall for vetical furnace that the utility model is built by laying bricks or stones is firm, good stability, lightweight, the long service life that has extended air-guiding wall, and the life-span of air-guiding wall is at least more than 2 years.This has reduced the furnace outage time of shaft furnace, and every year can voluminous pelletizing more than 10,000 ton, has improved productivity ratio and the economic benefit of shaft furnace.The utility model is when increasing air-guiding wall service life, and the reduction furnace pressure is played in building by laying bricks or stones the replacing time when also having shortened the air-guiding wall overhaul simultaneously, enlivens the purpose of furnace atmosphere.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
In figure: 1, brick body; 2, through hole; 3, rectangular preiection; 4, rectangular recess; 5, air-flow short slot; 6, flat chamfering; 7, projection; 8, groove.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the special-purpose preformed bricks with holes of air guide wall for vetical furnace of the present utility model comprises brick body 1, and described brick body 1 is rectangular, is provided with through hole 2 between two large faces of brick body 1, and it is central that through hole 2 is positioned at large face; On brick body 1 both ends of the surface along the length direction, one end is provided with rectangular preiection 3, and the other end is provided with rectangular recess 4 to reply rectangular preiection 3, and rectangular preiection 3 and two large faces are perpendicular; Be provided with air-flow short slot 5 on brick body 1 two sides along the length direction, short slot 5 is positioned at middle part, side and perpendicular with two large faces; Four corner angle sections of intersecting in the end face of brick body 1 and side are provided with flat chamfering 6; A large face at brick body 1 is arranged with two projections 7 along the length direction, and another large face is provided with two grooves 8 to tackling projection 7 along the length direction.The cross section of described air-flow short slot 5 is isosceles triangle, and drift angle is 90 degree.The area of plane of described flat chamfering 6 is half of air-flow short slot 5 areas.Described protruding 7 is two.
In work, can be according to the area of the mouth of width, length and the air-out of air guide wall for vetical furnace, set the size of the utility model brick body 1, this preformed bricks is at the air-flow short slot 5 of the both sides of brick body 1, can become a square hole by two brick phase spell shapes, its corner angle section four bricks are spelled mutually equally and can be formed a square hole, evenly distribute to reach air-flow, and the purpose of atmosphere stimulate.Adopt preformed bricks of the present utility model, reduced the quantity of brickwork joint, eliminated the internal stress of brick body, increase the stability of air-guiding wall, greatly improved the service life of air-guiding wall, reduced the furnace outage time of shaft furnace, every year can voluminous pelletizing more than 10,000 ton, has improved productivity ratio and the economic benefit of shaft furnace.
