Description

Technical Field

[0001] This utility model belongs to the technical field of converter tapping outlet, and particularly relates to a split-type seat brick for converter tapping outlet. Background Technology

[0002] As part of the converter's working lining, the taphole seat bricks are subjected to the scouring of molten steel during tapping and thermal shock damage from rapid temperature changes. The lifespan of the taphole is a crucial factor affecting the overall lifespan of the converter. Currently, most converter taphole seat bricks are of the split type, with some being of the integral type. Split-type bricks are assembled on-site, resulting in low installation precision, high requirements for masonry skills, and potential safety risks. Integral-type bricks, formed using isostatic pressing, struggle to guarantee product density, thus impacting the brick's lifespan. Therefore, developing a split-type converter taphole seat brick that ensures installation precision is key to solving this problem. Utility Model Content

[0003] The present invention provides a split-type seat brick for the tapping port of a converter.

[0004] This utility model is achieved through the following technical solution: it includes a grinding disc brick and a seat brick. The inner layer of the steel outlet is a grinding disc brick, and the outer layer is a seat brick body. The seat brick body includes seat brick A, seat brick B, seat brick C, and seat brick D. The inner walls of seat brick A, seat brick B, seat brick C, and seat brick D are arranged in an arc shape, and the angle corresponding to the arc of the inner wall of each seat brick is 90 degrees. The two outer walls intersect at right angles. The combination of seat brick A, seat brick B, seat brick C, and seat brick D forms a columnar structure with an inner circle and an outer square. Angle adjustment bricks are respectively set at the top and bottom of the seat brick body.

[0005] Furthermore, the A-type brick and the B-type brick have the same shape and structure. The thickness of one outer wall is the same at both ends, while the other outer wall is set in a sloping structure. The angle between the sloping surface and the horizontal line is 2 to 3 degrees, and the angle a1 of the sloping surface is 85 degrees, the angle a2 is 95 degrees, the angle a3 is 75 degrees, and the angle a4 is 105 degrees.

[0006] Furthermore, the C-type brick and the D-type brick have the same shape and structure. The thickness of one outer wall is the same at both ends, while the other outer wall is set in a sloping structure. The angle between the sloping surface and the horizontal line is 3 to 4 degrees, and the c1 angle of the sloping surface is 105 degrees, the c2 angle is 75 degrees, the c3 angle is 85 degrees, and the c4 angle is 95 degrees.

[0007] Furthermore, the angle adjustment bricks include adjustment brick E and adjustment brick F, both of which are triangular bricks. The bottom length of adjustment brick E is the same as the length of brick A or brick B, and the bottom length of adjustment brick F is the same as the length of brick C or brick D.

[0008] The beneficial effects of this utility model are: by prefabricating the steel tapping outlet as a whole structure, it is simple to construct. Then, by using a splicing connection combination, the installation level requirements are low and the construction speed is fast. While effectively ensuring the installation accuracy and density, it greatly reduces the difficulty of converter masonry construction and improves the service life of the steel tapping outlet seat bricks.
