Description
Technical field
The utility model belongs to metal continuous cast equipment technical field, is specifically related to a kind of structure simply, has the fixture of submersed nozzle during quick-replaceable continuous casting.
Background technology
In the continuous casting of metal is produced, the ladle that the good molten steel of refining is housed is transported to panoramic table, after panoramic table turns to pouring position, molten steel is injected tundish, molten steel to be assigned in each crystallizer by the mouth of a river and to go by tundish again.Crystallizer makes casting forming and quick solidification crystallization.Immersion water gap for continuously casting is the molten steel sleeve pipe of molding casting, plays the effect of insulation and isolated air.Along with the production capacity of conticaster is increasing, the life-span of tundish improves constantly, and the service life of submersed nozzle can not be synchronous with tundish.Due to reasons such as molten steel temperature change and field trashes in actual production process, being mingled with in molten steel is easily bonded on the wall of the mouth of a river with oxide, causes damming of the mouth of a river.Under continuous casting production, the life-span at the mouth of a river becomes one of principal element affecting rhythm of production, caster work rate and strand qualification rate.At present, submersed nozzle quick-changing technology generally adopts fixed frame and chute system, produces pressure and the old mouth of a river is shifted out, put into the new mouth of a river by cylinder.But when changing, accurately must locate the sliding position at the mouth of a river, and need to make the new mouth of a river and tundish bottom tightly contact by parts such as springs, change program complicated, the operating time is longer.Therefore, the fixture developing a kind of Quick-changeable immersed type water is the key point solved the problem.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, is easy to implement, safe and reliable, has the fixture of quick-replaceable middle water containing opening.At short notice by new and old outlet replacing, can not can have an impact to crystallizer liquid steel level, even the time of watering increases substantially, and reduce raw materials consumption, alleviate labor strength, ensure that slab quality and stable operation, Operation and Maintenance is simple.
The purpose of this utility model realizes like this, comprise suspension rod, mouth of a river cross bar, counterweight, mouth of a river inner ring, described suspension rod one end and mouth of a river cross bar are rotatably assorted and arrange, the other end is fixed on the outer wall of tundish, and described mouth of a river inner ring and counterweight are arranged at the two ends of mouth of a river cross bar respectively.
The utility model utilizes lever principle, adopt at the fixing suspension rod of tundish outer wall as fulcrum, mouth of a river cross bar can under the effect of counterweight, make the mouth of a river inner ring of the other end rise or decline, submersed nozzle is arranged in the inner ring of the mouth of a river, fast and safely can wrap separation submersed nozzle from centre.Rise the Balance weight end of mouth of a river cross bar, mouth of a river inner ring end wraps separation from centre, and fast old submersed nozzle is taken out, new submersed nozzle puts into mouth of a river inner ring, finally reduces Balance weight end, and mouth of a river inner ring end rises, and new submersed nozzle Fast Installation puts in place.Accurately can fixedly mount position by cross bar, mouth of a river inner ring and mouth of a river cross bar are rotatably assorted, and are convenient for changing submersed nozzle, and the submersed nozzle that can make contacts tightly with tundish bottom, no longer needs the parts such as spring.The utility model structure is simple, easy and simple to handle, safe and reliable, fast at short notice by new and old outlet replacing, can alleviate labor strength, ensure that slab quality and stable operation, improve the quality of products.

Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but limited the utility model never in any form, any conversion done based on the utility model training centre or replacement, all belong to protection domain of the present utility model.
As depicted in figs. 1 and 2, the utility model comprises suspension rod 1, mouth of a river cross bar 2, counterweight 3, mouth of a river inner ring 4, described suspension rod 1 one end and mouth of a river cross bar 2 are rotatably assorted and arrange, and the other end is fixed on the outer wall of tundish 5, and described mouth of a river inner ring 4 and counterweight 3 are arranged at the two ends of mouth of a river cross bar 2 respectively.
Described mouth of a river cross bar 2 one end is the circular arc of opening, and mouth of a river inner ring 4 is arranged in circular arc.
Described mouth of a river inner ring 4 is rotatably assorted with mouth of a river cross bar 2 and is connected.
Described mouth of a river inner ring 4 is rotationally connected by gudgeon 7 and mouth of a river cross bar 2.
Described mouth of a river cross bar 2 is split-type structural with counterweight 3.Can Fast Installation or take off counterweight.
Described counterweight 3 is detachable structure.Adjustable balance weight.
utility model works principle and the course of work:
The utility model utilizes lever principle, adopt at the fixing suspension rod of tundish outer wall as fulcrum, mouth of a river cross bar can under the effect of counterweight, make the mouth of a river inner ring of the other end rise or decline, submersed nozzle is arranged in the inner ring of the mouth of a river, fast and safely can wrap separation submersed nozzle from centre.When needing to change submersed nozzle, first the Balance weight end of mouth of a river cross bar is risen, mouth of a river inner ring end declines, submersed nozzle is allowed to be separated from tundish, then old submersed nozzle is taken out from the inner ring of the mouth of a river, new submersed nozzle is put into mouth of a river inner ring, finally reduces Balance weight end, mouth of a river inner ring end rises, and new submersed nozzle Fast Installation puts in place.Accurately can fixedly mount position by cross bar, mouth of a river inner ring and mouth of a river cross bar are rotatably assorted, and are convenient for changing submersed nozzle, and the submersed nozzle that can make contacts tightly with tundish bottom.Skilled operation personnel can change submersed nozzle in 1 second, do not affect the carrying out of cast.The utility model structure is simple, easy and simple to handle, safe and reliable, fast at short notice by new and old outlet replacing, can alleviate labor strength, ensure that slab quality and stable operation, improve the quality of products.
