Abstract
The utility model provides a convection plate for a bell-type annealing furnace, which is formed by welding an upper fanning strip and a lower fanning strip, a fixed substrate, a flow deflector and other parts. The convection plate is characterized in that a group of short fanning strips is added and welded at the lower part of the lower fanning strip to form a certain step with the inside and the outside diameters of the fanning strips of the convection plate, so as to avoid overflow of the inside and the outside diameters of steel coils, and prevent damage to the surfaces of the steel coils effectively. The convection plate overcomes the defects of the prior art, and has the advantages of reasonable structural design, low manufacturing cost, favorable useful effect, etc. In application effect, the appearance quality of the steel coil which has overflow edges before charging is obviously improved after discharging, thereby reducing waste products with damaged edges greatly, improving the product quality, and having remarkable economic benefit.
Description
Technical field
The utility model belongs to thermal treatment machinery equipment, and particularly a kind of annealing coil that prevents is pressed against the convection current plate of wound.
Background technology
At present, cold rolled strip coil generally all adopts the perhydro cover annealing, promptly in same stove the above coil of strip of three volumes is piled up and carries out anneal together, and this is one requisite important procedure in the coiled sheet production process.For fear of bonding between volume and the volume, help the circulation of gas stream in the stove, being provided with dividing plate between the coil of strip up and down, be commonly referred to the convection current plate.Existing convection current plate is to be made of last fanning strip, fixing base, inducer, following fanning strip.The convection current plate of this structure only is applicable to that scroll is good, no turriform, the smooth coil of strip of excessive end face.And in actual production; because the special type of heating of cold rolling hood type stove; if coil of strip overflowing of turriform, internal diameter and external diameter occur after curling; usually can be in the cover annealing treating processes by backfin; wherein partially folded place can bond; produce the quality problems that wound is pressed against on the coil of strip surface thus, serious place can the smooth ordinary production of influence.
Summary of the invention
Exist the surface to press against the deficiency of wound when coil annealing is handled in order to overcome existing bell-type furnace convection plate, improve the surface quality of finished product coil of strip, the utility model provides a kind of used for hood-type annealing furnace convection current plate.The convection current plate structure of this kind structure is reasonable in design, can prevent to handle the steel flanging part effectively and press against wound, reduces waste product, improves smooth hourly output, for enterprise wins considerable economic.
The technical solution of the utility model is, distribute according to existing coil of strip is outside, to have the convection current plate now is transformed, it is characterized in that welding one group short in the bottom of following fanning strip fans sheet, make it with existing convection current plate fanning strip in external diameter form certain step, can avoid overflowing of external diameter in the coil of strip so effectively, prevent that the surface from pressing against wound.
The utility model is compared with prior art has following advantage:
1. reasonable in design is cheap, is convenient to make and use;
2. prevent effectively that the coil of strip surface from pressing against wound, improve the quality of products;
3. remarkable in economical benefits reduced 70 tons in waste product by every month, and 1500 yuan of calculating of waste product and certified products price difference then year are created a benefit and are: 1500 yuan/ton * 70 tons * December=1,260,000 yuan.
Description of drawings
Fig. 1 is a radial view of the present utility model
Fig. 2 is a partial top view of the present utility model
Among the figure: fanning strip on 1,2 fixing bases, 3 inducers, 4 times fanning strips, 5 short fan sheets.
The utility model is mainly by upper fanning strip 1, fixing base 2, flow deflector 3, lower fanning strip 4, short fan Sheet 5 consists of. Be welded by fixing base 2 in the middle of upper fanning strip 1 and the lower fanning strip 4, at fixing base 3 flow deflectors 3 of welding on 2, short fan sheet 5 is long is 540-550mm, is welded direct to lower fanning strip 4 The bottom, short fan sheet 5 is 10-15mm apart from the convection-plate internal diameter during welding.
Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in detail:
The utility model as depicted in figs. 1 and 2, the fanning strip on the convection current plate cuts from a block plate, last fanning strip 1 is 20, long is 784mm; Following fanning strip 4 is 20, and long is 764mm; Be welded by fixing base 2 in the middle of last fanning strip 1 and the following fanning strip 4; 3 inducers 3 of every group are welded on the fixing base 2, play water conservancy diversion and fixed action; Short fan sheet 5 is 20, and is long for 545mm, is welded direct to down on the fanning strip 4.Overflow the wound of pressing against to coil of strip in order to reduce internal diameter, short fan sheet 5 should be 10mm apart from convection current plate internal diameter during welding.In addition, consider of the influence of convection current plate height, the existing size that goes up fanning strip 1 and following fanning strip 4 is reduced to 25mm by 30mm thermal treatment production capacity and water conservancy diversion.
The utility model is used in cold rolling hood type stove examination, from tracking effect, has the coil of strip of the bleeding edge later visual appearance of coming out of the stove obviously to improve before the shove charge, has significantly reduced because limit portion presses against and has hindered the waste product that causes, and has improved quality product.
