Description
Technical field
The utility model belongs to converter taphole refractory part field, particularly relates to a kind of coverter pig magnesia carbon brick.
Background technology
Converter taphole is that molten steel enters unique passage of ladle by converter.During tapping, high-temperature molten steel be born, the friction of slag washes away and oxidative attack, cause the tap hole life-span very low, need constantly to repair and change, thus 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 of pipe brick and brick cup designs 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, the work-ing life of brick cup is only about 600 times, and the frequency that converter tap hole tube brick and brick cup are repaired is higher, constrains the production cycle of converter.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, long service life, coverter pig magnesia carbon brick easy for installation.
For solving the problems of the technologies described above, the utility model realizes like this.
A kind of coverter pig magnesia carbon brick, it comprises interior brick external member and outer brick external member; Described interior brick external member and outer brick external member all adopt columnar structure; Described interior brick external member embeds in outer brick external member; The outer wall of described interior brick external member is fixed with spider; Back-up coat is provided with between described interior brick external member and outer brick external member.
As a kind of preferred version, the utility model is provided with assembling notch at the outer wall of described outer brick external member.
The utility model structure is simple, long service life, easy for installation, be aided with back-up coat by the double-deck socket join structure of interior brick external member and outer brick external member, can effectively decompose the stress distribution caused because of expanded by heating, reduce the frequency and the labour intensity of the repairing of tap hole refractory brick, alleviate molten steel high temperature oxidation and corrode and mechanical erosion destruction, work-ing life obviously extends.In addition, being fixed with spider by the outer wall of interior brick external member makes the utility model structure more firm.The utility model is provided with assembling notch by the outer wall of brick external member outside, makes it more convenient in transhipment installation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection domain of the present utility model is not only confined to the statement of following content.
Fig. 1 is the utility model one-piece construction schematic diagram.
Fig. 2 is that the utility model Figure 1A-A is to sectional view.
In figure: 1, interior brick external member; 2, outer brick external member; 3, spider; 4, back-up coat; 5, notch is assembled.
Embodiment
Shown in Fig. 1 and Fig. 2, coverter pig magnesia carbon brick, it comprises interior brick external member 1 and outer brick external member 2; Described interior brick external member 1 and outer brick external member 2 all adopt columnar structure; Described interior brick external member 1 embeds in outer brick external member 2; The outer wall of described interior brick external member 1 is fixed with spider 3; Back-up coat 4 is provided with between described interior brick external member 1 and outer brick external member 2.The utility model is provided with assembling notch 5 at the outer wall of described outer brick external member 2.
In the utility model, brick external member 1 and outer brick external member 2 are fixed to one another bonding respectively by back-up coat 4, with formed firm in brick and outer brick overall.
Be understandably, above about specific descriptions of the present utility model, only for illustration of the utility model, and the technical scheme be not limited to described by the utility model examples of implementation, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
Claims (2)
