Abstract
The utility model provides a connecting nozzle brick for quick sliding plate shifting, slag blocking and tapping device of a converter. The connecting nozzle brick is characterized in that a molten steel hole is formed in the center of the connecting nozzle brick and is round. The connecting nozzle brick is simple in structure, has a long service life and is suitable for the quick sliding plate shifting, slag blocking and tapping device of the converter.
Description
Technical field
The utility model is the mechanism refractory materials of metal liquid spout control flow, especially relates to the connection nozzle brick for converter furnace sliding plate quick change pushing off the slag tapping set.
Background technology
The slag that produces in the converter steelmaking is harmful to, and the lower cinder ladle during converter tapping is drawn together three parts: pre-slag, process slag and later stage slag.The extensive slag stopping method that adopts of converter tapping is that the gear pre-slag adopts slag retaining cap both at home and abroad at present, gear later stage slag employing slag-blocking ball, floating plug (slag blocking dart).Pneumatic dreg blocking and infrared lower slag inspection method also begin to be applied in the slag control under converter tapping gradually in addition, but these slag stopping methods all can not be realized the whole process pushing off the slag of forward and backward phase of converter tapping, particularly almost can not control pre-slag, bringing into of slag affected steel quality.
Therefore, provide a kind of connection nozzle brick that is used for converter furnace sliding plate quick change pushing off the slag tapping set that can have than the long life just to seem particularly necessary.
The utility model content
The purpose of this utility model provides a kind of connection nozzle brick for converter furnace sliding plate quick change pushing off the slag tapping set.
The utility model discloses a kind of connection nozzle brick for converter furnace sliding plate quick change pushing off the slag tapping set, and wherein, the central authorities of described connection nozzle brick have steel outlet hole.
The above-mentioned connection nozzle brick that is used for converter furnace sliding plate quick change pushing off the slag tapping set, wherein, the outer rim of described connection nozzle brick is provided with a circle flange.
The above-mentioned connection nozzle brick that is used for converter furnace sliding plate quick change pushing off the slag tapping set, wherein, described connection nozzle brick is oval or circular, its upper and lower end face is provided with the pressing plate groove.
The above-mentioned connection nozzle brick that is used for converter furnace sliding plate quick change pushing off the slag tapping set, wherein, the periphery cover of described connection nozzle brick has stirrup.
The above-mentioned connection nozzle brick that is used for converter furnace sliding plate quick change pushing off the slag tapping set, wherein, described steel outlet hole inwall is inlaid with the zirconium material.
Connection nozzle brick of the present utility model simple in structure, work-ing life is longer, is suitable for converter furnace sliding plate quick change pushing off the slag tapping set, has long work-ing life.
