Abstract
The utility model relates to a building structure of a ladle bottom working lining brick in the steel-making technical field. The ladle bottom working lining brick in a center zone in which a nozzle base brick and ventilating base bricks exist adopts the way that parallel arranged horizontal brick bodies and built brick bodies are crossly arranged, wherein the sides of the built brick bodies are vertical to the horizontal brick bodies, and the brick bodies at two sides of the center zone adopt a lambda-shaped arrangement way. The base line for positioning the ventilating base bricks and the water tap base brick is positioned at the place where the center line of the ventilating base bricks and the water tap base brick and the center line of a ladle lug shaft form an angle of 60.5 degrees. The building structure weakens the directional properties of the ladle bottom building structure, has reasonable structure, obviously improves the safety of a large ladle, and causes the shock resistance, the erosion resistance and the service life of the ladle to be greatly improved.
Description
Technical field
The utility model relates to the masonry construction of the working lining brick at bottom of ladle in the steelmaking technical field.
Background technology
World steel industry equipment constantly trends towards maximizing at present, series of new problems appears in building by laying bricks or stones of molten steel jar, reason and the increase of lining brick working strength owing to the design of brick type, lining brick obviously reduces service life, life-span can reach 120 times when molten steel jar lining brick uses on 180 tons of ladles, when on 260 tons of ladles, using, only can use about 70 times.The large-scale ladle of process for making is built by laying bricks or stones and is generally adopted compound masonry way both at home and abroad at present, and the mode difference of building by laying bricks or stones that adopts is very big to the ladle life influence.Build by laying bricks or stones at the bottom of the present stage molten steel jar jar and generally adopt flat block scheme, masonry construction as shown in Figure 2.Anisotropy at the bottom of the shortcoming of this masonry way is jar is stronger, because molten steel expanded by heating at the bottom of the jar in the splendid attire molten steel, temperature reduces the back and produces contraction, the expanded by heating effect at the jar end is different on two main directions of level, the extruding of brick at the bottom of direction causes jar easily, cause the breakage of brick, on another direction, then be prone to bigger slit, occurring a jar end brick in the process of using easily heaves, phenomenons such as steel base brick hikes up, the security that the serious threat iron and steel is produced, influenced the service life of whole molten steel jar to a great extent, production cost is increased.
Summary of the invention
For solving the problem that prior art exists, the purpose of this utility model provides a kind of masonry construction of working lining brick at bottom of ladle, this structure has weakened the anisotropy of masonry construction at the bottom of the molten steel jar jar, masonry construction rationally, significantly improve the security of large-scale molten steel jar, make at the bottom of the ladle resistance to impact, erosion resisting and improve greatly service life.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of masonry construction of working lining brick at bottom of ladle, it is the mode that the horizontal brick masonary that is arranged in parallel and side and horizontal brick masonary vertical direction are built the alternate layout of brick body by laying bricks or stones in the central area at pocket block, ventilative brick cup place that jar basic skill or training makes lining brick, is the mode of circular array at this both sides, central area brick body.
The baseline position that described ventilative brick cup, pocket block position becomes the position at 60.5 ° of angles for the center line of ventilative brick cup, pocket block with the molten metal ladle trunnion center line.
Compared with prior art, the beneficial effects of the utility model are:
Adopt this structure to build working lining at the bottom of the molten steel jar jar by laying bricks or stones, weakened the anisotropy of masonry construction at the bottom of the molten steel jar jar, masonry construction is reasonable, impact resistance, corrosion resistance at the bottom of the molten steel jar have been strengthened, reduce jar breakage of end brick and fall the possibility of brick, improve molten steel jar safety in utilization, reduce cost, improved service life.
Description of drawings
Fig. 1 is the schematic diagram of the masonry construction at the bottom of the molten steel jar jar.
Among the figure: the ventilative brick cup 3-pocket block 4-gudgeon of the ventilative brick cup 2-of 1-
Fig. 2 is the flat masonry construction figure that builds working lining brick at bottom of ladle in the prior art.
The specific embodiment
See Fig. 1, the masonry construction of working lining brick at bottom of ladle, it is the mode that the horizontal brick masonary that is arranged in parallel and side and horizontal brick masonary vertical direction are built the alternate layout of brick body by laying bricks or stones in the central area at pocket block 3, ventilative brick cup 1, ventilative brick cup 2 places that jar basic skill or training makes lining brick, is the mode of circular array at this both sides, central area brick body.The baseline position that ventilative brick cup 1, ventilative brick cup 2, pocket block 3 position becomes the position at 60.5 ° of angles for the center line of ventilative brick cup, pocket block with the molten metal ladle trunnion center line.
Be example with 260 tons of ladles below, introduce the building method of working lining brick at bottom of ladle, this method may further comprise the steps:
1) will breathe freely brick cup, pocket block positions, and finds baseline accurately, and the baseline position that ventilative brick cup, pocket block position becomes the position at 60.5 ° of angles for the center line of ventilative brick cup, pocket block with the molten metal ladle trunnion center line.
2) in ventilative brick cup both sides to molten steel jar tank skin along the ventilative horizontal successively block of brick cup width, and it is concordant with ventilative brick cup one side to build brick body one side by laying bricks or stones; The brick body that the opposite side of ventilative brick cup is built by laying bricks or stones is and the vertical direction of above-mentioned horizontal brick masonary, builds by laying bricks or stones successively to tank skin;
3) build by laying bricks or stones successively to molten steel jar tank skin in the pocket block both sides, along the horizontal successively block of pocket block width, and it is concordant with pocket block one side to build brick body one side by laying bricks or stones; The brick body that the opposite side of pocket block is built by laying bricks or stones is and the vertical direction of above-mentioned horizontal brick masonary, builds by laying bricks or stones successively to tank skin;
4) build one deck brick body by laying bricks or stones in the outside direction vertical with above-mentioned horizontal brick masonary of pocket block 1, ventilative brick cup 3, tank skin is close in both sides;
5) look for the center of step 4) institute brick masonary then, vertically this row brick body is built by laying bricks or stones, first brick and center centering;
6) then with step 5) institute brick masonary vertical direction, build by laying bricks or stones successively from the center to the both sides tank skin;
7) above-mentioned steps is carried out repeatedly, build do lining cutting until the jar basic skill or training and to finish, forming jar end working lining and in the central area at pocket block, ventilative brick cup place be the horizontal brick masonary that is arranged in parallel and side and horizontal brick masonary vertical direction and build the mode of the alternate layout of brick body by laying bricks or stones, be the mode of the circular array of expansion gradually, even layout at this both sides, central area brick body.
