Abstract
The utility model relates to a continuous casting field especially relates to a device of package end vortex in middle of eliminating continuous casting, and its characterized in that, brick seat shoulder is provided with the resistant firebrick of whirlpool that disappears on the middle package mouth of a river, should disappear resistant firebrick of whirlpool and radially set up for the mouth of a river. Compared with the prior art, the beneficial effects of the utility model are that: by changing the ladle bottom structure, the flow field of molten steel at the bottom of the tundish is changed, on one hand, the eddy slag entrainment of the molten steel can be effectively avoided from being brought into a crystallizer, the casting blank quality is improved, on the other hand, the phenomenon that the liquid level of the tundish on the next ladle at night is lower than the critical liquid level and the pouring is forced to be stopped during the ladle changing process can be avoided, the pouring stopping liquid level of the tundish can be further reduced, the slag entrainment caused by the pouring stopping at the low liquid level is avoided, and the metal yield is improved.
Description
Technical field
The utility model relates to the continuous casting field, relates in particular to a kind of device of eliminating eddy current at the bottom of the continuous casting tundish bag.
Background technology
Because continuous casting tundish bag primary coat skinning loam height is concordant with pocket block, molten steel is in low liquid level and has very big kinetic energy in tundish, in the process that flows into crystallizer, because sudden change of flow speed, follow-up molten steel can not in time add to the centre, produces vortex phenomenon inevitably, very easily causes molten steel volume slag, also be unfavorable for simultaneously the steel inclusion come-up, cause scum silica frost above the molten steel to be involved in crystallizer and make strand the many problems of inclusion defect occur.
Summary of the invention
The purpose of this utility model provides a kind of device of eliminating eddy current at the bottom of the continuous casting tundish bag, and the vortex phenomenon when solving the low liquid level of tundish molten steel makes strand the many problems of inclusion defect occur.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of device of eliminating eddy current at the bottom of the continuous casting tundish bag is characterized in that the brick cup shoulder is provided with the whirlpool refractory brick that disappears on middle water containing opening, and this whirlpool refractory brick that disappears radially is provided with respect to the mouth of a river.
Compared with prior art, the beneficial effects of the utility model are: by changing structure of ladle bottom, changed the flow field of molten steel at the bottom of the tundish bag, can effectively avoid molten steel eddy current volume slag to bring crystallizer on the one hand, improve slab quality, can avoid on the other hand in changing jar process, owing to wrapping liquid level subcritical liquid level in evening, the last machine of next jar is forced to disconnected watering, also can further reduce tundish and stop watering liquid level, needn't worry that low liquid level stops watering to cause the volume slag, improve recovery rate of iron.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: the 1-brick cup 4-mouth of a river 5-bag end refractory brick under the brick cup 3-mouth of a river that disappears on the refractory brick 2-mouth of a river, whirlpool
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, a kind of device of eliminating eddy current at the bottom of the continuous casting tundish bag, brick cup 2 shoulders are provided with the whirlpool refractory brick 1 that disappears on middle water containing opening, and this whirlpool refractory brick 1 that disappears radially is provided with respect to the mouth of a river 4.General pocket block is a up-down structure, be embedded with the mouth of a river 4 on the mouth of a river under the brick cup 2 and the mouth of a river in the middle of the brick cup 3, at the bottom of the continuous casting tundish bag on the refractory brick 5 the coating height concordant with brick cup 2 on the mouth of a river, by changing structure of ladle bottom, changed the flow field of molten steel at the bottom of the tundish bag, the mutual collision effect of flowing that stops owing to the whirlpool refractory brick 1 that disappears with steel, molten steel flows into rotation no longer at a high speed in the tundish process, avoided the generation of eddy current, can effectively avoid molten steel eddy current volume slag to bring crystallizer on the one hand, improved slab quality, can avoid on the other hand in changing jar process, be forced to disconnected watering, also can further reduce tundish and stop watering liquid level owing to the last machine of next jar wraps liquid level subcritical liquid level in evening, needn't worry that low liquid level stops watering and cause the volume slag, improve recovery rate of iron.
