Description
Technical field
The utility model relates to a kind of annealing furnace convection current plate.
Background technology
Cold rolled sheet, belt steel product have that surface quality is good, dimensional precision is high and advantages such as favorable mechanical, processing performance, is widely used in all trades and professions.Along with science and technology development, a series of machineries of cold rolling industry, electrical equipment, control, roll cooling problem have obtained corresponding solution, and roll speed is also improving constantly.For recovery rate and the milling train effective operation rate that improves product, must improve the length of stable rolling section, it is heavy just to strengthen volume.The maximum volume-weight of cold rolled strip has reached 46 tons at present.And thermal treatment is in order to eliminate work hardening, to recover Plastic Deformation as the cold-rolled products important procedure.Bell type annealing furnace is annealed to the demanding upright volume of bell furnace that all adopts of deep drawability because the annealing performance is better than continuous annealing furnace.
Effective bearing surface of former convection current plate is fan-shaped distribution, so effectively the Area of bearing percentage is a definite value, when one timing of annealing material, proportion is definite value just, and pressure is only relevant with stacking height; Former convection current plate does not adopt negative taper on the structure, whole bearing surface is dull and stereotyped, the end face stressed area is less, the flat coil of strip end face actual form that do not meet of while, cause coil of strip Internal and external cycle two end flangings serious, produce the adhesion of annealing back portion, have a strong impact on the recovery rate and the effective operation time of finished product unit.
Summary of the invention
The purpose of this utility model be to design a kind of pressure with coil diameter increase reduce, thermo-efficiency height, energy-conservation, the annealing furnace convection current plate that can make volume property retention unanimity inside and outside the coil of strip after the annealing.
For achieving the above object, the utility model comprises a kind of annealing furnace convection current plate, comprises a plurality of upper and lower support plates, substrate; Described upper and lower support plate, be fixed on the substrate; Described a plurality of upper and lower support plate is arranged twist, and rotating to an angle from the relative external diameter of internal diameter on the structure forms volution convection current plate and can accomplish that effective Area of bearing heavily increases with the coil of strip volume and increases, and effectively the Area of bearing rate increases thereupon; Adopt volution to distribute simultaneously and make every layer of focus deflection, focus is scattered along the coil of strip interlayer, reduced internal-external temperature difference, and the focus number when having increased convection current.
As further improvement of the utility model, the substrate between the described adjacent upper and lower support plate respectively is provided with at least one turbulent bar up and down.
Further improve as of the present utility model, respectively have at least one turbulent ventilation duct on the described upper and lower support plate.
Described turbulent bar is arranged at the outlet both sides of ventilation duct respectively.
Described turbulent ventilation duct one end leads to upper and lower support plate, outer end, and the other end leads to upper and lower support plate, sidepiece.
Set up turbulent bar and turbulent gas ventilation duct, strengthen blast, change wind direction, strengthen convection current intralamellar part thermal conduction and transmission of heat by contact, reduced interlayer conduction distance, strengthened the heat transfer by conduction effect and made heat transfer rate obviously accelerate thereby reduce the thermal capacitance of convection current plate own.
Described upper and lower support plate is an inclined wedge-shaped.
There is a gradient described upper and lower support plate outer end, overflows to adapt to the interlayer of steel band when batching deceleration.
Advantage of the present utility model is: adopt flow is arranged twist, volution convection current plate can be accomplished the increase with the coil of strip coil diameter, and effectively the Area of bearing rate increases thereupon; Adopting spiral to distribute scatters focus; Set up turbulent bar and turbulent gas ventilation duct, strengthen blast, change wind direction; Reduce the weight of convection current plate own, thereby the thermal capacity that reduces the convection current plate strengthens conducted inside, reduced interlayer conduction distance, strengthened the heat transfer by conduction effect, can make heat transfer rate accelerate; In shove charge weight unanimity; Specification is identical; Under the identical prerequisite of annealing process, annealing back coil of strip internal and external parts consistency of performance improves big the raising than fan-shaped convection current plate; The back coil of strip end face convection current plate impression of coming out of the stove obviously improves, for subsequent handling has been created favourable condition; Operation defective bonding obviously reduces, and the related defects of Yin Faing also obviously reduces thus.
