Abstract
The utility model relates to a new type of furnace base liner for the spherical-bottom converter furnace including a furnace cytase; the furnace cytase includes combined central bricks, the combined central bricks comprise a central brick and a number of rings of single furnace-based crown brick, rings around the combined central brick are compounded and laid by two kings of furnace-based crown bricks with the same molding section and a furnace-based straight brick. The beneficial effects of the utility model are: 1) simple structure of the central brick, convenient masonry construction; simple appearances and few types of the furnace-based crown bricks and the furnace-based straight brick of different rings, compounding closely with each other, effectively eliminating the thermal stress concentration; 2) adjusting in longitude and latitude direction when laying, strong applicability; 3) convenient and swift masonry construction, wide scope of applicability; 4) high efficiency and low production cost, wide applicability scope, no broken bricks in use; the service life of the new furnace liners which are made of the same material has a 20 percent increase compared to the other two types.
Description
Technical field
The utility model relates to field of metallurgy, concrete relates to converter furnace bottom working lining at the bottom of a kind of novel ball.
Background technology
At present, known tube spherical furnace bottom the working lining spherical and converter of conisphere shape is built institute's use brick shape by laying bricks or stones two kinds, perpendicular wide wedge brick " ten " font of a kind of employing is built by laying bricks or stones, its shortcoming is toward faulting of slab ends occurring in the building process all around from the furnace bottom central section, the closer to faulting of slab ends is high more on every side, undertighten and brickwork joint are many with cooperating between the permanent layer, bottom-blowing air feed element is in the layout and installation inconvenience of furnace bottom, last ring brick needs clip processing to contact with the molten bath working lining is fine, because how the clip amount causes disconnected brick easily during building construction, thereby influences work-ing life; Another kind is built by laying bricks or stones for annular, the centre adopts 2～4 perpendicular wide wedge brick combinations to be processed into truncated cone-shaped or approximate terrace with edge shape center brick, each ring adopts different ball dome brick annulars to build by laying bricks or stones on every side, its shortcoming is that brick shape is many, though cooperate between brick and the brick closely, but be difficult for adjusting and control, the manufacturing expense height, the building construction difficulty is big.
Summary of the invention
Problem to be solved in the utility model is to propose converter furnace bottom working lining at the bottom of a kind of novel ball at above-mentioned prior art, and its used brick shape is few, build by laying bricks or stones and cooperate tightly, and brickwork joint is less.
The utility model is to address the above problem the solution that is adopted to be: converter furnace bottom working lining at the bottom of a kind of novel ball, include the furnace lining body, described furnace lining body includes the combination center brick, difference is that described combination center brick is closely combined together and formed by a center brick and the single furnace bottom wedge brick of the ring of numbers surface and the surface of center brick by furnace bottom wedge brick vertical and horizontal, and described center brick is positive 16 terrace with edge shapes.
Press such scheme, described combination center brick is combined by positive 16 terrace with edge shape center bricks and the single furnace bottom wedge brick of 2～4 rings.
Press such scheme, each ring forms for furnace bottom wedge brick and brick the building of the straight shape of furnace bottom with identical moulding cross section around the described combination center brick.
Press such scheme, each ring is that two kinds of furnace bottom wedge bricks with identical moulding cross section and the straight shape brick of a kind of furnace bottom cooperate to build by laying bricks or stones and form around the described combination center brick.
Combination center brick of the present utility model is combined by the center brick and the single furnace bottom wedge brick of 2～4 rings of positive 16 terrace with edge shapes, between each ring and with center brick between cooperates tightly, brickwork joint is even, suitable dry method is built by laying bricks or stones, can effectively avoid thermal stresses to concentrate the disconnected brick that causes, described furnace bottom wedge brick is wedge shape at horizontal and vertical both direction, can on the longitude and latitude both direction, adjust during the sphere masonry of well, thereby suitability is stronger, brick figurate number amount is less, around the combination center brick each ring by 2 kinds of furnace bottom wedge bricks and the straight shape brick of a kind of furnace bottom totally three kinds of brick shapes can satisfy and build needs by laying bricks or stones, can finely satisfy layout and the installation of bottom-blowing air feed element simultaneously at furnace bottom.The multiple bottom brick of lining thickness unanimity can be produced by shared same mold cavity, thereby can significantly improve production efficiency, reduces production costs, and the inconsistent various bottom bricks of lining thickness can cooperate well.
The beneficial effects of the utility model are:
1) center brick is simple in structure, and building construction is convenient; The furnace bottom wedge brick and the straight shape brick of the furnace bottom profile of each ring is simple, brick shape kind is few, cooperates closely each other, can eliminate the stress concentration under hot effectively;
Can adjust on the longitude and latitude both direction when 2) building by laying bricks or stones, suitability is stronger, can finely satisfy layout and the installation of bottom-blowing air feed element at furnace bottom;
3) building construction is convenient and swift, and is applied widely, can satisfy 30～320 tons of various tubes spherical furnace bottom working linings spherical and converter of conisphere shape and build needs by laying bricks or stones;
4) brick shape is simple, brick shape kind is few and common mode ratio height, production efficiency height, production cost are low, applied widely, does not have disconnected brick in the use, and the novel furnace lining of identical material is compared work-ing life and can be improved more than 20% with other two kinds.
