Abstract
The invention discloses a drying method for surface coating of strip steel, the drying method includes the procedures as follows: after the strip steel being normally and continuously coated on the production line, the hot wind is used for preliminary drying the coat surface, simultaneously the electromagnetic induction is utilized to heat the inside of the strip steel for inner drying, then the hot wind is utilized again for the final drying the coat surface. The invention dries the coat of the strip steel by outside hot wind and inner heating, the temperature changes uniformly in the dryingprocess of the coat, the invention can effectively eliminate coat crazing and can prevent uneven depth caused by the production accumulation of the coat; the invention utilizes simultaneous drying process for the outside and the inside of the coat, achieving the same effect; the invention can decrease the heating temperature for the electromagnetic induction the strip steel, thereby being useful tocool the production of the strip steel.
Description
Technical field
The present invention relates to a kind of drying method of coated tape steel production process floating coat.
Background technology
For satisfying the demand of market to high-quality coated tape steel, the coating of belt steel surface also requires to have higher surface quality except that playing antisepsis, as higher coating fineness and uniform coating layer thickness.In the production process of coated tape steel, the coating drying means is bigger to the influence of coating surface quality.In the prior art, method to belt steel surface coating drying is to adopt electromagnetic induction to make the inner eddy current heat that produces of band steel come drying belt steel face coat, this method has that technology is simple, the fireballing advantage of coated and dried, but on production line, realizing flash baking, must correspondingly improve the electromagnetic induction temperature of band steel inside, can cause belt steel temperature to rise so again, be unfavorable for the cooling of finished strip; In addition; because this method is single from inside to outside coating to be carried out drying processing; defectives such as coating segmentation crack, coating layer thickness be inhomogeneous appear in the band steel regular meeting that actual production goes out; have a strong impact on the surface quality of coated tape steel; reduce the qualification rate or the product hierarchy of product, directly caused economic loss.
Summary of the invention
The furnace drying method that the purpose of this invention is to provide a kind of belt steel surface coating, the temperature when handling to eliminate belt steel surface coating segmentation crack, mass defect in uneven thickness, can also reduce coated and dried simultaneously helps the cooling of finished strip.
A kind of furnace drying method of belt steel surface coating, the steps include: to be with steel behind normal coating continuously on the production line, adopt hot blast that coating surface is carried out preliminary drying earlier, adopt electromagnetic induction heating band steel inside to carry out interior baking again, and then adopt hot blast that coating surface is carried out final drying processing.
Further, the hot blast temperature regulation and control are 120 ℃～200 ℃ scopes;
Owing to the present invention adopts external hot air and interior mode of heating that coating is dried, the coated and dried process temperature changes evenly, so can effectively eliminate the coating segmentation crack and prevent coating production accumulation and uneven thickness; Owing to dry processing simultaneously inside and outside adopting coating, reaching under the same effect situation, can reduce the heating-up temperature of band steel electromagnetic induction, so help cooling of belt steel product.
Description of drawings
Figure is a band steel coating oven dry schematic flow sheet.
Among the figure: 1. electromagnetic induction heating furnace, 2. inlet bellows, 3. outlet bellows, 4. coated tape steel, 5. hot blast.
The specific embodiment
As shown in the figure, adopt electricity, coal gas or steam that cleaned air passes is heated by heat exchanger, the hot blast 5 that obtains is sent into the inlet bellows 2 and the outlet bellows 3 of electromagnetic induction heating furnace 1 respectively, when the coated tape steel behind the coating 4 passes through inlet bellows 2, electromagnetic induction heating furnace 1 and outlet bellows 3 continuously, in inlet bellows 2, realize coating surface prebake, baking in 1 heating tape steel is realized in electromagnetic induction heating furnace is realizing final oven dry by outlet bellows 3 backs; By adjusting the heat that adds of electricity, coal gas or steam heat exchanging device, the control hot blast temperature is 120 ℃～200 ℃ scopes.
Claims (3)
1. the furnace drying method of a belt steel surface coating, comprise and adopt the electromagnetic induction heating oven dry, it is characterized in that: the band steel is after finishing normal coating continuously on the production line, adopt hot blast that coating surface is carried out prebake earlier, adopt electromagnetic induction heating band steel inside to carry out interior baking again, and then adopt hot blast that coating is finally dried.
2. the furnace drying method of belt steel surface coating according to claim 1, it is characterized in that: the final oven dry of prebake of described employing hot blast and hot blast is to add loading port bellows (2) respectively and export bellows (3) in the porch of the coated tape steel (4) of electromagnetic induction heating furnace (1) and exit, and feeds respectively to it that hot blast (5) realizes.
3. the furnace drying method of belt steel surface coating according to claim 2 is characterized in that: hot blast (5) temperature is 120 ℃～200 ℃ scopes.
