Description
Technical field
The present invention relates to a kind of refractory materials, the especially pocket block of continuous casting production filling pipe end.
Background technology
Middle water containing opening brick cup is located under middle water containing opening, and in shock platforms, the molten steel in tundish passes through centre
Tundish nozzle pocket is flowed into cooling in the crystallizer in shock platforms, and passes through the continuous vibrations of shock platforms and realize drawing steel.
In order to reduce the erosion of filling pipe end, middle water containing opening brick cup is mainly around the contact area for reducing molten steel and filling pipe end
It is realized with molten steel flow speed is reduced, current middle water containing opening brick cup molten steel import is too big, and molten steel impacts filling pipe end area also phase
It is stronger to filling pipe end corrosion dynamics to larger, continuous casting cannot be coordinated to carry out prolonged straightening, affect production efficiency, secondly
The excessive formation vortex of molten steel inlet openings, field trash can enter in crystallizer, influence billet quality.
Invention content
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which filling pipe end use can be extended by providing one kind
The middle water containing opening brick cup in service life opens up through-hole by the diameter of diminution molten steel import and on the outside of middle water containing opening brick cup,
It effectively prevent molten steel to the corrosion of filling pipe end and the generation of vortex.
Technical solution：In order to reach foregoing invention purpose, the present invention is specifically achieved like this：One kind can extend upper water
The middle water containing opening brick cup of mouth service life, includes the matrix of cylinder, and matrix central upper portion offers the molten steel import of taper,
Matrix underpart offers molten steel outlet, the filling pipe end mounted on molten steel outlet, which is characterized in that described matrix side is provided with 3
Through-hole in sustained height and mutually in 120 degree distributions between through-hole, and is connected with molten steel import, via height and centre
It is concordant that packet basic skill or training makees layer height.It is clean conducive to remaining steel flow, moreover it is possible to prevent the cast later stage to be vortexed, can prevent to be mingled with
Object enters in steel billet, while also having decelerating effect by the molten steel that the hole enters in pocket block.
Further, the through-hole is taper.It is more smooth that molten steel flows into filling pipe end.
Further, the through-hole wall is cased with hole set.Prevent through-hole from causing to block because resistance to material is loose.
Further, the hole set material is to iron diamond spar chamotte.High temperature resistant, compactness are high.
Further, the hole set is of coupled connections with through-hole for labyrinth type.Prevent molten steel impact make hole set enter molten steel into
Mouthful.
Further, the hole set outer diameter matches for the taper of taper and through-hole, and internal diameter is also taper.Conducive to steel flow
Enter molten steel import.
Advantageous effect：The present invention has the following advantages compared with traditional technology：
1, by reducing molten steel inlet diameter, reduce corrosion of the molten steel to filling pipe end.
2, by opening up through-hole, clean conducive to remaining steel flow, the later stage prevents vortex from occurring.
3, increase hole in through-hole wall to cover, further preventing tundish through-hole, there is a situation where block.

Fig. 2 is the middle water containing opening brick cup vertical view that can extend filling pipe end service life.
Fig. 3 is the structure sectional view for the middle water containing opening brick cup main body set with holes that can extend filling pipe end service life
Specific implementation mode
Embodiment 1：As shown in Figure 1, a kind of middle water containing opening brick cup extending filling pipe end service life, including cylinder
Matrix 3,3 central upper portion of matrix offers the molten steel import 2 of taper, and 3 lower part of matrix offers molten steel outlet 5, is mounted on steel
The filling pipe end 4 of water out, which is characterized in that 3 side of described matrix is provided with 3 through-holes 1, in sustained height and phase between through-hole 1
Mutually in 120 degree of distributions, and it is connected with molten steel import 2.
Embodiment 2：As shown in figure 3, on the basis of embodiment 1, to prevent molten steel from flowing into molten steel import 2 by 1 through-hole
During pocket block refractory material occur loosen be scattered cause block through-hole 1,1 inner wall of through-hole increase hole set 6, hole
The material of set 6 is the phenomenon that ironing diamond spar chamotte, effectively can prevent through-hole from blocking.Pass through step between through-hole 1 and hole set 6
Shape matches, and the outer diameter taper of hole set 6 is identical with the taper of through-hole 1, hole when multiple cooperation prevents molten steel impact opening from covering
Set 6 is pushed away such as molten steel import 2, and molten steel is caused to block.It is taper that hole, which covers 1 internal diameter, is conducive to molten steel and flows into.
Molten steel is entered by molten steel import 2, is gone out by filling pipe end 4, into crystallizer.By reducing the straight of molten steel import 2
Diameter reduces impact of the molten steel to filling pipe end 4, while 1 height of through-hole is made with tundish packet basic skill or training to increase the wall thickness of matrix 3
It is clean that layer height is concordantly conducive to remaining steel flow, moreover it is possible to prevent the cast later stage to be vortexed, field trash can be prevented to enter steel billet
In, while also having decelerating effect by the molten steel that the hole enters in pocket block, extend the tundish working time.
