Description
Technical field
The utility model belongs to converter taphole refractory part field, relates in particular to the carbon-free corundum brick of a kind of coverter pig.
Background technology
The converter taphole life-span is one of important technical indicator of converter steelmaking.Due to the direct erosion and the violent scour that frequently stand high-temperature molten steel and hyperoxia voltinism slag, the effect of rapid heat cycle causes tap hole very easily to destroy in addition.The length in its life-span directly has influence on converter smelting cycle, STEELMAKING PRODUCTION rate and pushing off the slag effect, and then affects steel quality.
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, the phenomenons such as the cracked and tap hole brick cup floating of brick cup easily appear, 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.
The utility model content
The utility model 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 brick of coverter pig easy for installation.
For solving the problems of the technologies described above, the utility model is to realize like this.
The carbon-free corundum brick of a kind of coverter pig, it comprises interior block assembly and outer block assembly; Described interior block assembly and outer block assembly are columnar structure; Described interior block assembly is embedded in outer block assembly; Is furnished with the fastening bed of material between described interior block assembly and outer block assembly.
Described interior block assembly comprises interior brick the first subassembly and interior brick the second subassembly; The upper and lower surface of described interior brick the first subassembly is provided with annular notch; The corresponding annular notch of the upper and lower surface of described interior brick the second subassembly place is provided with annular projection; Interior brick the first subassembly and interior brick the second subassembly are through annular projection and fixedly clamping of annular notch.
Described outer block assembly comprises outer brick the first subassembly and outer brick the second subassembly; The upper and lower surface of described outer brick the first subassembly is provided with annular notch; The corresponding annular notch of the upper and lower surface of described outer brick the second subassembly place is provided with annular projection; Outer brick the first subassembly and outer brick the second subassembly are through annular projection and fixedly clamping of annular notch.
As a kind of preferred version, the outer wall of interior brick the first subassembly described in the utility model and interior brick the second subassembly is fixed with respectively endless belt.
The utility model is simple in structure, long service life, easy for installation, by interior block assembly and outer block assembly double braid covering connecting structure and be aided with the fastening bed of material, can effectively decompose the stress distribution caused because of expanded by heating, reduced the frequency and labour intensity that tap hole refractory brick is repaired, alleviated the erosion of molten steel high temperature oxidation and mechanical erosion and destroyed, obviously extend work-ing life.Brick the first subassembly and interior brick the second subassembly in the utility model, outer brick the first subassembly and outer brick the second subassembly are respectively by the fixedly clamping design of annular projection and annular notch, realized the resistance to overturning of tap hole refractory brick, in addition, the endless belt that interior brick the first subassembly described in the utility model and interior brick the second subassembly outer wall are fixed with has further been strengthened the stability of system.
