A take vortex to cover all cold 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 both sides of cooling chamber are provided with the vortex cover, vortex cover symmetry cover is established on steel band both sides limit. The utility model discloses take vortex to cover all cold hydrogen annealing furnace utilizes vortex cover to reduce the cooling blast and in the convection current speed of steel band limit portion, makes the horizontal cooling of steel band more even, improved the quality of steel band.
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 cooling section cools steel band in this type of annealing furnace, rely on the convective heat exchange of atmosphere completely, and gaseous exchange heat exchange always makes that steel band edge temperature is low and medium temperature is high, this inhomogeneous cooling transversely not only can produce limit wave, affects strip shape quality; Steel band internal stress also can be made to increase, have impact on the application of steel band further.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hydrogen annealing furnace all cold with flow disturbing cover and utilizes flow disturbing cover to reduce the convection velocity of cooling draught in steel band edge, and laterally cooling is more even to make steel band, improves the quality of steel band.
The utility model is achieved in that a kind of hydrogen annealing furnace all cold with flow disturbing cover; with the working direction of steel band for positive dirction; comprise inlet seal, heating chamber, cooling room, deflector roll section, return pass and exit seal in turn; described heating chamber, cooling room, deflector roll section are 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 both sides of described cooling room are provided with flow disturbing cover, and described flow disturbing cover symmetry is located at steel band dual-side.
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 all cold hydrogen annealing furnace of the utility model band flow disturbing cover utilizes flow disturbing cover to reduce the convection velocity of cooling draught in steel band edge, and laterally cooling is more even to make steel band, improves the quality of steel band.
