Abstract
The utility model discloses a kind of high performance and long service life tapping hole brick of converter, including brick cup and pipe brick, brick cup and pipe brick are cylindrical, the upper surface of brick cup is provided with an annular groove, the lower surface of pipe brick is provided with and the annular protrusive board of annular groove matching, the first through hole with its concentric is provided with the inside of annular groove, the second through hole with its concentric is provided with the inside of annular protrusive board；Compared with existing technical scheme, high performance and long service life tapping hole brick of converter of the present utility model, pass through brick cup and pipe brick bilayer socket join structure, improve installation rate, gap between annular groove and annular protrusive board can effectively decompose the stress distribution because of caused by expanded by heating, the frequency and labor intensity of tapping hole refractory brick repairing are reduced, the erosion of molten steel high-temperature oxydation is alleviated and mechanical erosion destroys, service life is obviously prolonged.
Description
Technical field
A kind of high performance and long service life tapping hole brick of converter is the utility model is related to, belongs to converter taphole refractory part technology
Field.
Background technology
The tapping hole brick of converter life-span is one of important technical indicator of pneumatic steelmaking.Due to being frequently subjected to high-temperature molten steel and height
The direct erosion of oxidisability clinker and violent scour, the in addition effect of rapid heat cycle cause tapping hole to be highly vulnerable to breakage.Its life-span
Length directly influences converter smelting cycle, STEELMAKING PRODUCTION rate and pushing off the slag effect, and then influences steel quality.The intact degree of tapping hole
The quantity of slag under converter is directly control, and alloy yield and rear step treatment process are brought and directly affected.
At present, brick cup of converter tapping hole uses single square structure substantially, and the brick design of pipe brick and brick cup is unreasonable,
Stress non-homogeneity when pipe brick and heated brick cup, easily there is phenomena such as brick cup fragmentation and tapping hole brick cup floating, converter taphole
Pipe brick and the frequency that brick cup is repaired are higher, constrain the production cycle of converter.
The content of the invention
（One）Technical problems to be solved
To solve the above problems, the utility model proposes a kind of high performance and long service life tapping hole brick of converter.
（Two）Technical scheme
High performance and long service life tapping hole brick of converter of the present utility model, including brick cup and pipe brick, brick cup and the pipe brick are equal
For cylindrical, the upper surface of the brick cup is provided with an annular groove, and the lower surface of the pipe brick is provided with and annular groove matching
Annular protrusive board, the first through hole with its concentric is provided with the inside of the annular groove, is provided with the inside of the annular protrusive board same with it
Second through hole in the center of circle.
As preferable technical scheme, the thickness of the annular protrusive board is the 8/9-9/10 of the groove width of the annular groove.
As preferable technical scheme, the height of the annular groove and annular protrusive board is respectively the height of brick cup and the pipe brick
The 1/6-1/5 of degree.
As preferable technical scheme, the first through hole and the second through hole match.
（Three）Beneficial effect
Compared with prior art, it has the advantages that the utility model：High-performance of the present utility model is long-lived
Tapping hole brick of converter is ordered, by brick cup and pipe brick bilayer socket join structure, installation rate is improved, between annular groove and annular protrusive board
Gap can effectively decompose the stress distribution because of caused by expanded by heating, reduce tapping hole refractory brick repairing the frequency and work
Intensity, alleviates the erosion of molten steel high-temperature oxydation and mechanical erosion destroys, and service life is obviously prolonged.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only

Embodiment
A kind of high performance and long service life tapping hole brick of converter as shown in drawings, including brick cup 1 and pipe brick 2, the He of brick cup 1
Pipe brick 2 is cylindrical, and the upper surface of the brick cup 1 is provided with an annular groove 11, and the lower surface of the pipe brick 2 is provided with and described
The annular protrusive board 21 that annular groove 11 matches, the inner side of annular groove 11 are provided with the first through hole 12 with its concentric, the annular
The inner side of protrusive board 21 is provided with the second through hole 22 with its concentric.
Further, the thickness of the annular protrusive board 21 is the 8/9-9/10 of the groove width of the annular groove 11, is so both protected
The stable socket between brick cup and pipe brick has been demonstrate,proved, gap has been left again and decomposes stress distribution caused by expanded by heating.
Further, the height of the annular groove 11 and annular protrusive board 21 is respectively the height of the brick cup 1 and pipe brick 2
1/6-1/5。
Further, the through hole 22 of first through hole 12 and second matches.
High performance and long service life tapping hole brick of converter of the present utility model, pass through phase interworking between annular groove and annular protrusive board
Close, allow brick cup and pipe brick to realize double-deck socket join structure, improve installation rate, molten steel is flowed into by first through hole and the second through hole
Ladle, the gap between annular groove and annular protrusive board can effectively decompose the stress distribution because of caused by expanded by heating, reduce out
The frequency and labor intensity of steel mouth refractory brick repairing, alleviate the erosion of molten steel high-temperature oxydation and mechanical erosion destroys, service life
It is obviously prolonged.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design conception is not departed from, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, the scope of protection of the utility model, this reality all should be dropped into
With new claimed technology contents, all record in detail in the claims.
