Description
Technical field
The utility model belongs to refining furnace dip pipe and circulating pipe refractory lining technical field, and in particular to one kind is used for essence
The monoblock type refractory lining of furnace dip pipe and circulating pipe.
Background technology
As steel production capacity constantly expands, the continuous aggravation of competition, RH vacuum refining furnaces are as the most advanced of current main-stream
Vacuum refining device, vital effect is played in the smelting of high-level steel grade；Before steel treatment, first by dip pipe
Immerse in pending ladle molten steel.Two dip pipes connected with vacuum tank, one be tedge, one be down-comer.By
Argon gas constantly is blown into molten steel in tedge, is blown into that when gases are heated, they expand, so as to drive molten steel constantly to rise, flows through vacuum tank
The gases such as argon gas, hydrogen, carbon monoxide in molten steel are pumped under vacuum conditions.The molten steel of degassing is due to the work of self gravitation
With ladle is flowed into through down-comer again, this is constantly circulated repeatedly；With the accumulation and progress of technology, SECONDARY REFINING IN A VACUUM CHAMBER it is continuous
Improve, be to improve product quality necessary means.
At present, domestic dip pipe is built by laying bricks or stones respectively with circulating pipe, and under the service condition of refining furnace, molten steel is largely circulated
Brick body is washed away larger, in addition to the requirement to resistance to material performance is higher, the stability requirement to molten steel circulating channel structure is more
It is high.Dip pipe builds the problem of being primarily present by laying bricks or stones respectively with circulating pipe in the prior art is：Because molten steel largely circulate to brick
Body wash away it is larger, easily cause brick body separation, make the refractory material stability of the whole vacuum tank circulatory system not high；Inventor's base
It has developed in the prior art the defects of a kind of for refining furnace dip pipe and the monoblock type refractory lining of circulating pipe, can solve the problem that
The problems of the prior art.
Utility model content
The utility model is in order to solve the above-mentioned technical problem, there is provided a kind of entirety for refining furnace dip pipe and circulating pipe
Formula refractory lining, its design structure is simple, scientific and reasonable, easy to use；By by two layers of circulating pipe brick of refining furnace circulating pipe
Built by laying bricks or stones with alternative form, and entirety is connected in impregnated tube liner position brick body combined crosswise；Improve in the vacuum tank circulatory system
Dip pipe and the stability of circulating pipe refractory material brick body.
Technical scheme is used by the utility model：A kind of monoblock type fire resisting for refining furnace dip pipe and circulating pipe
Liner, including circulating pipe lining brick, dip pipe lining brick；Circulating pipe lining brick is located at the bottom of refining furnace vacuum tank, circulating pipe lining brick with
The bottom connection of refining furnace vacuum tank；Circulating pipe lining brick staggeredly builds connection by laying bricks or stones along molten steel circulation passage；Dip pipe lining brick is set
In the bottom of circulating pipe lining brick, dip pipe lining brick staggeredly builds connection by laying bricks or stones along molten steel circulation passage；Circulating pipe lining brick and dip pipe
The brick body intersection of lining brick is built connection by laying bricks or stones and is integral.
The brick body bumps of the circulating pipe lining brick and dip pipe lining brick are staggeredly built connection by laying bricks or stones and are integral.
The use process of this monoblock type refractory lining for refining furnace dip pipe and circulating pipe is：When the leaching of refining furnace
Stain pipe is inserted into when filling in molten steel ladle, and the tedge of dip pipe is pumped into molten steel from ladle the vacuum tank of refining furnace
In vacuum chamber, after degassing process, molten steel is flowed into ladle from the down-comer of dip pipe, is so moved in circles, and is just realized
The degassing process of molten steel, protection refining is now just served for the monoblock type refractory lining of refining furnace dip pipe and circulating pipe
The effect of stove steel body；Above procedure is exactly this using for the monoblock type refractory lining of refining furnace dip pipe and circulating pipe
Journey.
Concavo-convex staggeredly build by laying bricks or stones of the brick body of the circulating pipe lining brick and dip pipe lining brick is integral；The main mesh so set
Be in order to by the way that concavo-convex staggeredly build by laying bricks or stones of the brick body of circulating pipe lining brick and dip pipe lining brick is integral, to strengthen circulating pipe
The stability of lining brick and dip pipe lining brick, extend the service life of circulating pipe lining brick and dip pipe lining brick；Solve dip pipe with
The problem of circulating pipe traditional structure is scattered and avoids the unstability of brick body straight joint, while solve dip pipe and disperse with circulating pipe
The insecurity of structure.
The circulating pipe lining brick and dip pipe lining brick are annular；The main purpose so set is to pass through annular
Circulating pipe lining brick forms the longer circulating pipe of service life, and it is longer to form service life again by the dip pipe lining brick of annular
Dip pipe.
The beneficial effects of the utility model：The technical program provides a kind of entirety for refining furnace dip pipe and circulating pipe
Formula refractory lining, solve the problems, such as that dip pipe disperses with circulating pipe traditional structure and avoids the unstability of brick body straight joint, together
When solve the insecurity of dip pipe and circulating pipe dispersed structure；Improve dip pipe and circulating pipe in the vacuum tank circulatory system
The stability of refractory material brick body, dip pipe is easily changed with circulating pipe, avoided straight joint from wearing steel, prevent circulation canal float, protect
The service life of resistance to material is demonstrate,proved, improves the profitability of enterprise.
