An inner loop hydrogen annealing furnace to the direction of advance of steel band is the positive direction, in order including entry sealed, heating chamber, cooling chamber, turn to roll segment, recirculation channel and exit seal, heating chamber, cooling chamber, turn to the protective atmosphere intercommunication in roll segment and the recirculation channel, the heating chamber is for taking horse indirect furnace heating not, the end section intercommunication of cooling chamber has the protective atmosphere supplementary device, the initial section of cooling chamber passes through return line and protective atmosphere supplementary device intercommunication, the last series connection of return line has heat exchanger, circulating fan and gas dryer. The utility model discloses with the continuous loop filter of the atmosphere in the stove dry, reduce the dew point, the cooling chamber is sent back to by the atmosphere supplementary device again to loop filter's atmosphere, can also play cooling gas's effect, has practiced thrift the energy consumption of cooling zone, the atmosphere that consequently circulates always generally speaking can not the outer energy consumption of increase, has improved the annealing quality.
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.
In this type of annealing furnace, hydrogen bout ferric oxide, iron protoxide, Z 250 etc. carry out redox reaction generation iron and water, need to reduce the humidity in annealing atmosphere and oxygen level as far as possible to realize the reduction reaction of hydrogen to ferriferous oxide, because oxygen level is far below extraneous air in stove, therefore external oxygen is easy to infiltrate in stove and hydrogen reaction generation water, the humidity of furnace atmosphere will be improved so further, have impact on annealing effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of internal recycle hydrogen annealing furnace, and continuous for the atmosphere in stove circulating filtration is dry, reduce dew point, the atmosphere of circulating filtration sends cooling room back to by atmosphere supplementary device again, the effect of cooling gas can also be played, save the energy consumption of cooling section, therefore generally speaking circulating atmosphere always can't increase additional energy, improves annealing quality.
The utility model is achieved in that a kind of internal recycle 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, the end section of described cooling room is communicated with protective atmosphere supplementary device, the initial section of described cooling room is communicated with protective atmosphere supplementary device by return line, described return line is in series with interchanger, recirculation blower and gas flow dryer.
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.
Described interchanger, recirculation blower and gas flow dryer move towards in sequential series along air-flow.
The utility model internal recycle hydrogen annealing furnace is dry by continuous for the atmosphere in stove circulating filtration, reduce dew point, the atmosphere of circulating filtration sends cooling room back to by atmosphere supplementary device again, the effect of cooling gas can also be played, save the energy consumption of cooling section, therefore generally speaking circulating atmosphere always can't increase additional energy, improves annealing quality.
