Description
Technical field
The utility model relates to annealing furnace field, particularly relates to a kind of hydrogen annealing furnace.
Background technology
Stainless steel clean annealing plate is widely used due to the light had as good solidity to corrosion and minute surface, and stainless steel clean annealing plate adopts stainless steel bright continuous annealing equipment carry out anneal to stainless steel plate and obtain.At present, when cold rolled stainless steel band is annealed in continuous annealing furnace, steel band sequentially passes through heating zone, cooling section, roll chamber and the boot segment containing annealing atmosphere along working direction, and wherein heating zone is indirec radiation heating, and fuel is in radiator tube combustion.
When in this type of annealing furnace, cooling section cools steel band, in order to avoid steel band sideslip in annealing furnace needs to give extra drafting force tension steel band when conveying steel belt, drafting force is too small cannot avoid steel belt deviation, and drafting force is excessive easily makes again thinner belt plate shape quality be affected.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air cushion correction hydrogen annealing furnace and the middle part of deflector roll section is provided with a pair air cushion shower nozzle, the power of lifting utilizing air cushion to produce changes the frictional force lateral distribution between steel band and deflector roll, thus the correction realized steel band, when without the need to provide very long draft power, ensure that the stability of annealing furnace work, improve the quality of steel band.
The utility model is achieved in that a kind of air cushion correction hydrogen annealing furnace, with the working direction of steel band for positive dirction, comprise inlet seal in turn, heating chamber, cooling room, deflector roll section, return pass and exit seal, described heating chamber, cooling room, deflector roll section is communicated with the protective atmosphere in return pass, heating chamber is band horse indirect heater not, a pair air cushion shower nozzle is provided with in the middle part of described deflector roll section, described air cushion shower nozzle is arranged on the below of steel band, steel band held by the air cushion that air cushion shower nozzle produces, air cushion shower nozzle described in a pair is symmetrical arranged with the axis of steel band.
Described heating chamber comprises inner and outer tubes, and described horse is not for being coated on the outer tube outside interior pipe, and fuel burns by the internal pipe heating of radiation in outer tube, is run in the guide in interior pipe by the steel band heated.
Described inlet seal and exit seal are roll seal sealing mechanism.
Described inlet seal and exit seal contour.
Described cooling room is multistage continuous coo1ing room, is made up of altogether three continuous print cooling sections.
The end section of described cooling room is communicated with protective atmosphere supplementary device.
The utility model air cushion correction hydrogen annealing furnace is provided with a pair air cushion shower nozzle at the middle part of deflector roll section, the power of lifting utilizing air cushion to produce changes the frictional force lateral distribution between steel band and deflector roll, thus the correction realized steel band, when without the need to provide very long draft power, ensure that the stability of annealing furnace work, improve the quality of steel band.
