The brick comprises an inner brick suite (1) and an outer brick suite (2), wherein the inner brick suite (1) is arranged in the outer brick suite (2); a strengthening layer is arranged between the inner brick suite and the outer brick suite (2); the inner brick suite (1) comprises an inner brick first unit piece (101) and an inner brick second unit piece (102); an inner brick fixing insert piece (401) is arranged in an inner brick fixing through hole (301); the outer brick suite (2) comprises an outer brick first unit piece (201) and an outer brick second unit piece (202); an outer brick fixing insert piece (402) is arranged in an outer brick fixing through hole (302). The brick disclosed by the invention is long in service life and convenient to install.
Description
Technical field
The invention belongs to converter taphole refractory part field, relate in particular to the carbon-free corundum refractory brick of a kind of coverter pig.
Background technology
Converter taphole is that molten steel is entered unique passage of ladle by converter.During tapping, bear the friction of high-temperature molten steel, slag and wash away and oxidative attack, cause the tap hole life-span very low, need to constantly repair and change, thereby not only can affect the production cycle, and have influence on steel quality and production stability.
At present, brick cup of converter tapping hole adopts single square structure substantially, the brick type design of pipe brick and brick cup is unreasonable, Stress non-homogeneity when pipe brick and brick cup are heated, easily there is the phenomenons such as the cracked and tap hole brick cup floating of brick cup, be only 600 left and right the work-ing life of brick cup, and the frequency that converter tap hole tube brick and brick cup are repaired is higher, restricted the production cycle of converter.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, long service life, the carbon-free corundum refractory brick of coverter pig easy for installation.
For solving the problems of the technologies described above, the present invention realizes like this.
The carbon-free corundum refractory brick of coverter pig, it comprises interior brick external member and outer brick external member; Described interior brick external member is placed in outer brick external member; Between described interior brick external member and outer brick external member, be provided with back-up coat.
Described interior brick external member comprises interior brick first module part and interior brick second unit part; Described interior brick first module part and interior brick second unit part are provided with interior brick fixed via; In described interior brick fixed via, be provided with interior brick fixing pluge.
Described outer brick external member comprises outer brick first module part and outer brick second unit part; Described outer brick first module part and outer brick second unit part are provided with outer brick fixed via; In described outer brick fixed via, be provided with outer brick fixing pluge.
As a kind of preferred version, the outer wall of first module part of the present invention and interior brick second unit part is fixed with respectively annular projection.
The present invention is simple in structure, and long service life is easy for installation.By interior brick external member and outer brick external member double braid covering connecting structure and be aided with back-up coat, can effectively decompose the stress distribution causing because of expanded by heating, the frequency and labour intensity that tap hole refractory brick is repaired have been reduced, alleviated the erosion of molten steel high temperature oxidation and mechanical erosion and destroyed, obviously extend work-ing life.The present invention is provided with interior brick fixed via by interior brick first module part and interior brick second unit part; In interior brick fixed via, be provided with interior brick fixing pluge and outside be provided with outer brick fixed via on brick first module part and outer brick second unit part, in described outer brick fixed via, be provided with the resistance to overturning that the structure designs such as outer brick fixing pluge have realized tap hole refractory brick, in addition, the outer wall of first module part of the present invention and interior brick second unit part is fixed with respectively annular projection, and it is the stability of consolidation system further.
