Description
Technical field
The utility model belongs to Ladle Treatment technical field in converter steelmaking, relates in particular to a kind of without scaling loss oxygen lance shower nozzle.
Background technology
In steel-making converter is produced, the ladle transporting, store molten steel is the requisite visual plant of whole operation.Ladle comes and goes and transports molten steel between converter, continuous casting, due to slag, slag inclusion can not be avoided completely during converter tapping, add in storage with transport molten steel process, for reducing molten steel thermal radiation, add a large amount of insulation at molten steel upper layer and carry out lid agent, after casting machine has watered molten steel, remaining bits and cold steel can cover collector nozzle of ladle and bottom blowing brick, if do not processed the production that can affect next stove.General method leads to oxygen with oxygen lance to purge the bits covered on the mouth of a river, bottom blowing brick, and in treating processes, oxygen also can be lighted oxygen lance self, make its consumption oxygen lance that burns while blowing and burning cold steel, residue.The oxygen lance of one 4 meters long can only process cold steel and the residue on about 10 35 tons bottom of steel ladle gas permeable brick surfaces, therefore the oxygen lance of about 1.5 tons will be consumed when monthly dress bag processes gas permeable brick and the mouth of a river, the method consumes a large amount of oxygen lances, be unfavorable for reducing Iron and Steel Production cost, cause the waste of production cost.
Summary of the invention
A kind of structure that the purpose of this utility model is to overcome above-mentioned shortcoming and provides is simple, high temperature resistant, flame retardant resistance is high, practical inexpensive without scaling loss oxygen lance shower nozzle.
The utility model object and solve its technical problem underlying and realize by the following technical solutions: of the present utility model without scaling loss oxygen lance shower nozzle; comprise protective casing, interior pipe, connecting joint; interior pipe is equipped with in protective casing inside; it is characterized in that: be bonded with adiabator layer between protective casing and interior pipe, protective casing one end is connected with connecting joint.
Above-mentioned without scaling loss oxygen lance shower nozzle, wherein: described protective casing and connecting joint pass through screwed connection.
Above-mentioned without scaling loss oxygen lance shower nozzle, wherein: described protective casing is steel pipe.
Above-mentioned without scaling loss oxygen lance shower nozzle, wherein: described interior pipe.
Above-mentioned without scaling loss oxygen lance shower nozzle, wherein: described lagging material layer thickness is 2mm.
The utility model compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, in described steel protective casing and pyroceramic, between pipe, be bonded with adiabator layer, utilize that it is high temperature resistant, oxygen and oxygen lance separate by flame-retarding characteristic, stop the burning of oxygen pipe to consume; There is connecting joint protective casing one end by screwed connection, if after a shower nozzle damage, it can be unloaded from screw thread, changes another and continues to use, easy to operate, and saves the consumption of oxygen pipe, effective.In a word, the utility model structure is simple, high temperature resistant, flame retardant resistance is high, practicality is inexpensive, is applicable to operate without scaling loss oxygen blast.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Identify in figure:
1, protective casing; 2, adiabator layer; 3, interior pipe; 4, connecting joint.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to the utility model proposes without scaling loss oxygen lance shower nozzle embodiment, structure, feature and effect thereof, be described in detail as follows.
See Fig. 1; of the present utility model without scaling loss oxygen lance shower nozzle, comprise protective casing 1, interior pipe 3, connecting joint 4, interior pipe 3 is equipped with in protective casing 1 inside; wherein: between protective casing 1 and interior pipe 3, be bonded with adiabator layer 2, protective casing 1 one end is connected with connecting joint 4.Described protective casing 1 passes through screwed connection with connecting joint 4.Described protective casing 1 is steel pipe.Described interior pipe 3 is high temperature ceramic material.Described adiabator layer 2 thickness is 2mm.Described protective casing 1 is formed by the steel pipe manufacturing of Φ 25*2, long 150mm.Described connecting joint 4 round steel of Φ 25 is made, long 35mm.The specification of described interior pipe 3 is Φ 17*2, long 135mm.The long 15mm of thread of described protective casing 1 and connecting joint 4.
During use, connecting joint 4 one end not with screw thread is welded on oxygen lance front end, then by screw thread the protective casing 1 of shower nozzle is connected on connecting joint 4 and namely can uses, if after a shower nozzle damages, can unload from screw thread, change another and continue to use.From service condition, this shower nozzle use easy to operate, high temperature resistant, flame retardant resistance is high, save the consumption of oxygen pipe, effective, be applicable to operate without scaling loss oxygen blast.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, anyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
