Description
Technical field
The present invention relates to a kind of sealing device, more particularly, to a kind of sealing device for annealing unit.
Background technology
Annealing furnace is directly connected to the final mass of product made from steel as the visual plant of annealing unit, its air-tightness, meanwhile,
The working environment of annealing unit also depends on the bubble-tight quality of annealing furnace.Generally, the strip after entrance cleaning passes through to turn to
Roller enters in stove and is heated, and the gas tightness in annealing furnace porch is then particularly important.Existing annealing furnace entrance one
As using a pair sealed roller to be opened/closed, furnace gas is sealed, in this case, opening degree between sealed roller with
And the leakiness to furnace gas for the gap between sealed roller and furnace shell, that is, the seal degree of annealing furnace have the most direct shadow
Ring.At annealing unit, the effect of setting sealing device is the leakage in order to reduce protective gas in annealing furnace, and prevents the external world
Air enters in stove and pollutes furnace atmosphere.
At present, domestic adopted sealing roller arrangement is although have certain sealing effectiveness for annealing furnace entrance, but
Remain following defect:
1) in process of production, because sealed roller is opened and closed by air cylinder driven, the adjustment of its roller gap needs often to exist
During maintenance, the stroke of cylinder is adjusted, wastes time and energy for producers, and precision is not also high.
2) in process of production, annealing in-furnace temperature is higher, and sealing roller segment roll surface communicates with stove, and part roll surface is then
Expose at ambient temperature, excessive temperature differentials may lead to roller entirety temperature distortion, especially in roller exception stall, deform feelings
Condition is even more serious.
3) prevent although being provided with heat-barrier material along roller length direction due to there is certain interval between sealed roller and furnace shell
The leakage of furnace gas, but the gap of roller two ends end is not provided with veil, furnace atmosphere leakage situation is in rod end
More serious.
4) certain protective gas can be leaked at sealing rod, lack protective gas retracting device, in the stove leaking out
There is greatly harm to operating environment in protective gas, and can cause certain actual bodily harm to staff.
Content of the invention
It is an object of the invention to provide a kind of annealing furnace inlet seal device, it has preferable sealing property, can
Easily operate to seal the entrance of annealing furnace, and sealed roller can be avoided under the temperature difference of annealing furnace inner and outer boundary environment
Deformation.
To achieve these goals, the present invention proposes a kind of annealing furnace inlet seal device, and it is close that it includes at least one pair of
Envelope roller, described annealing furnace inlet seal device also includes:
Sealed roller roll gap adjustment device, comprising: guide rail, the bearing block of described sealed roller and guide rail slidable connection, institute
State the direction that spacing between the length direction of guide rail and two sealed rollers extends identical；Driving element, it is with described each sealing
The bearing block correspondence of roller is fixedly connected, and drives described bearing block along slide；
Cooling device,, above sealed roller, described cooling device is used for being arranged on the furnace shell of annealing furnace, this cooling for it
Device includes: at least one water tank, which is provided with water inlet and delivery port, is provided with the deflector interlocking up and down in described water tank；
End seal,, located at the axial end portion of sealed roller, this end seal includes for it: sealing plate, it is vertical
In the axial direction setting of sealed roller, this sealing plate covers the gap between sealed roller and annealing furnace furnace shell；
Sealed roller axial sealer, its along sealed roller axial direction between sealed roller and the furnace shell of annealing furnace,
This sealed roller axial sealer includes: along the strip pressing plate that extends of axial direction of sealed roller, described strip pressing plate will be along close
The encapsulant that envelope roller axial direction extends is fixed between sealed roller and the furnace shell of annealing furnace.
Because the degree size between the gap degree between sealed roller and sealed roller and annealing furnace decides annealing furnace
Sealing property, accordingly, it would be desirable to limit both sizes as much as possible.
Larger roller gap can be adjusted by sealed roller roll gap adjustment device, between it obtains between two rods
Gap is only capable of passing through from annealing furnace bottom for certain thickness strip, and the bearing block of connection corresponding with each roller is driven by driving element
Dynamic, can slidably reciprocate along the length direction of guide rail, due to two sealings in the length direction and a pair of sealed roller of guide rail
The direction that spacing between roller extends is identical, two sealed roller meetings therefore, in the sliding process of roller, in a pair of sealed roller
Produce move toward one another or counter motion, that is, two sealed roller is increasingly nearer or two sealed rollers are more and more remote, it is right to this makes it possible to
Gap between sealed roller carries out quick regulation, ensure that the sealing between sealed roller.
By end seal and sealed roller axial sealer, then ensure that the sealing between sealed roller and annealing furnace
Property.
In order to preventing the part of contacting external air of sealed roller and being in the temperature difference between the part of atmosphere in stove
The excessive and thermal bending deformation that leads to sealed roller, arranges cooling device on the furnace shell of annealing furnace and above sealed roller, should
Cooling device includes being provided with the water tank of water inlet and delivery port, and is then provided with water tank and guided for cooling liquid
Deflector.
Further, in annealing furnace inlet seal device of the present invention, above-mentioned sealed roller roll gap adjustment device
