Abstract
The utility model relates to a refractory material, especially the mouth of a river brick cup at mouth of a river on continuous casting tundish, including columniform base member, conical molten steel import has been seted up at base member upper portion center, and the molten steel export has been seted up to the base member lower part, installs the mouth of a river on the molten steel export, its characterized in that, open the base member side has 3 through-holes, just is 120 degrees distributions each other at same height between the through-hole to be linked together with the molten steel import. The diameter of a molten steel inlet is reduced, the through holes are increased, the impact of the molten steel on a water feeding port is reduced, the height of each through hole is flush with the height of a tundish bottom working layer, residual molten steel flow is clean, eddy current can be prevented from occurring in the later pouring period, impurities can be prevented from entering steel billets, the molten steel entering a nozzle brick cup through the through holes also has a speed reducing effect, and the pouring time of the tundish is prolonged.
Description
Technical field
The utility model relates to a kind of refractory materials, the especially pocket block of continuous casting production filling pipe end.
Background technique
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 the crystallizer in shock platforms continuous vibration realization drawing steel that is cooling, and passing through shock platforms.
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, it is not able to cooperate continuous casting and carries out prolonged straightening, affects production efficiency, secondly
The excessive formation vortex of molten steel inlet openings, field trash can enter in crystallizer, influence billet quality.
Utility model content
Purpose of utility model: it the purpose of this utility model is that in view of the deficiencies of the prior art, provides on one kind can extend
The middle water containing opening brick cup of mouth of a river service life, by reducing the diameter of molten steel import and being opened on the outside of middle water containing opening brick cup
If through-hole, it effectively prevent molten steel to the corrosion of filling pipe end and the generation of vortex.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: Yi Zhongke
The middle water containing opening brick cup for extending filling pipe end service life, including cylindrical matrix, matrix central upper portion offers taper
Molten steel import, the filling pipe end that matrix underpart offers molten steel outlet, is mounted on molten steel outlet, which is characterized in that described matrix side
Face is provided with 3 through-holes, in sustained height and mutually in 120 degree distributions between through-hole, and is connected with molten steel import, through-hole height
It is concordant that degree with tundish packet basic skill or training makees layer height.It is clean conducive to remaining steel flow, moreover it is possible to prevent the casting later period to be vortexed, it can be with
It prevents field trash from entering 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 pink fused alumina chamotte.High temperature resistant, compactness are high.
Further, the hole set and through-hole are of coupled connections 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.
The utility model has the advantages that the utility model compared with traditional technology, has the advantage that
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 period prevents vortex from occurring.
3, increase hole in through-hole wall to cover, further preventing tundish through-hole, there is a situation where block.
Detailed description of the invention
Fig. 1 is the middle water containing opening brick cup main structure cross-sectional view that can extend filling pipe end service life.
Fig. 2 is the middle water containing opening brick cup top view that can extend filling pipe end service life.
Fig. 3 is the structure sectional view that can extend the middle water containing opening brick cup main body set with holes of filling pipe end service life
Specific embodiment
Embodiment 1: as shown in Figure 1, a kind of middle water containing opening brick cup that can extend 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 phenomenon that material of set 6 is pink fused alumina 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, and multiple cooperation prevents molten steel impact opening when covering hole
6 push-in molten steel import 2 of set, causes molten steel 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 to increase the wall thickness of matrix 3, while 1 height of through-hole and tundish packet basic skill or training make
It is clean that layer height is concordantly conducive to remaining steel flow, moreover it is possible to prevent the casting later period 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.
