Description
Technical field
The present invention relates to make steel ladle, the especially prefabricated section of usefulness in the flat block method in ladle wall, slag line district.
Background technology
The ladle of steel-making usefulness, its structure mainly comprises the housing of ladle, is compounded in the permanent layer on the said inner walls, and builds prefabricated section or machine made brick on said permanent layer inwall by laying bricks or stones.Said permanent layer inwall can be divided into three zones, slag line district on bag base area, Bao Bi (being the circular arc sidewall) district and Bao Biqu top.
At present; Said prefabricated section or machine made brick are generally laid on end at the masonry way in ladle wall district and slag line district; Be that prefabricated section or machine made brick are built (extremely shown in Figure 9 like Fig. 4) by laying bricks or stones with leptoprosopy 1 ' level, wide 2 ' vertical mode; Because prefabricated section or machine made brick leptoprosopy 1 ' (end face when promptly building by laying bricks or stones and bottom surface) in sintering procedure can occur spending error e, f (as shown in Figure 4) and center line size biased error b (as shown in Figure 7) slightly, for the same a collection of prefabricated section or the machine made brick of spending error e, f (as shown in Figure 4) slightly arranged, when laid on end; If guarantee the smooth of bottom leptoprosopy 1 ' (being the bottom surface); Just i, j, k puzzle joint (as shown in Figure 5) be can occur,, m, n puzzle joint (as shown in Figure 6) just can be occurred if guarantee adjacent wide 2 ' smoothly; For same a collection of prefabricated section or the machine made brick of own centre line size biased error b (as shown in Figure 7), when laid on end, if guarantee the smooth of bottom leptoprosopy 1 '; A puzzle joint (as shown in Figure 8) just can appear; If guarantee adjacent wide 2 ' smoothly, d puzzle joint (as shown in Figure 9) just can appear, and puzzle joint is prone to cause the working lining back side drill steel that is built into by said prefabricated section or machine made brick; Influence in service life to ladle is big, and the ladle security of operation is constituted a threat to.In addition, because prefabricated section or machine made brick leptoprosopy 1 ' size are shorter, the overlapping probability of vertical puzzle joint when building by laying bricks or stones between the adjacent circular layer increases greatly, influences the intensity of ladle; Laid on end prefabricated section or machine made brick be because its more than 2 times of width highly normally, prefabricated section or machine made brick in the high and low temperature change procedure along the expansion on the short transverse, shrink and can not effectively decompose and cause the ladle transverse joint to worsen.
Summary of the invention
The objective of the invention is to: the flat block method of a kind of prefabricated section in ladle wall, slag line district is provided; Can guarantee the flatness of building by laying bricks or stones; Avoid spending the puzzle joint that error, center line size biased error are produced slightly because of same area with a collection of prefabricated section or machine made brick; Effectively decompose prefabricated section or expansion and the contraction of machine made brick in the high and low temperature change procedure, the security and the service life of improving ladle.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Prefabricated section of the present invention is in the flat block method in ladle wall, slag line district; Wherein used prefabricated section comprises A, B two symmetrical rectangle sides; Symmetrical up and down and be parallel to each other wedge shape end face and wedge shape bottom surface; And when building by laying bricks or stones towards the wide end surface of ladle wall permanent layer and the narrow end surface relative with this wide end surface; The width of said narrow end surface along continuous straight runs is greater than the distance between said wedge shape end face and the wedge shape bottom surface, and said wide end surface is plane or arc surface, and said narrow end surface is plane or circular arc concave surface; Concrete grammar comprises the following steps:
A. with first prefabricated section horizontal positioned, its wedge shape bottom surface is downward, and wide end surface is towards the ladle wall permanent layer;
B. with second prefabricated section horizontal positioned, build by laying bricks or stones an one of which side alignment and a side being close to first block of said prefabricated section, and its wedge shape end face is downward, and wide end surface is towards the ladle wall permanent layer;
C. with the 3rd said prefabricated section horizontal positioned, build by laying bricks or stones an one of which side alignment and another side of being close to second block of said prefabricated section, its wedge shape end face upwards, wide end surface is towards the ladle wall permanent layer;
D. repeat above-mentioned steps b and c successively, build other prefabricated section by laying bricks or stones, build completion by laying bricks or stones up to first circular layer;
E. upwards build second circular layer, the 3rd circular layer by laying bricks or stones according to above-mentioned each steps in sequence, up to having built Bao Biqu and slag line district by laying bricks or stones, the vertical puzzle joint between adjacent two circular layers is misplaced distribution.
Prefabricated section of the present invention or machine made brick; Because the width of said narrow end surface along continuous straight runs is greater than the distance between said wedge shape end face and the wedge shape bottom surface; Compare with existing laid on end, the overlapping probability of the vertical puzzle joint when building by laying bricks or stones between the adjacent circular layer is minimum, helps the raising of ladle intensity; Prefabricated section or the flat ladle working layer of building out of machine made brick with this structure; Along the bed joint quantity of short transverse than existing brick-on-end many many; Be generally two to three times; Can prefabricated section or machine made brick effectively be decomposed in the expansion and the contraction of high and low temperature change procedure, avoid ladle working layer transverse joint to worsen, improve the security and the service life of ladle.
The present invention is a kind of to use said prefabricated section or the machine made brick flat block method in ladle wall, slag line district; Because the width of the narrow end surface along continuous straight runs of said prefabricated section or machine made brick is greater than the distance between said wedge shape end face and the wedge shape bottom surface, thereby guaranteed that the present invention can adopt described flat block method to build by laying bricks or stones; Owing to adopted described flat block method in Bao Biqu and the slag line district of ladle, the center line size biased error that occurs at same position with a collection of prefabricated section or machine made brick can be able to elimination because of contiguous prefabricated or machine made brick rectangle sides turn around up and down to build to connect; Spend error slightly on the one hand because of said rectangle sides turns around up and down to build to connect to be improved, on the other hand, adopt prefabricated section of the present invention or machine made brick, because of highly reducing, the depth of parallelism of wedge shape end face and wedge shape bottom surface is easy to guarantee, spends error slightly and be further improved.Thereby flat block method of the present invention, can guarantee the flatness of circular layer, avoid the appearance of puzzle joint drill steel phenomenon, improve the security and the service life of ladle.
