Description
[technical field]
The present invention relates to a kind of manufacture method of steel plate, relate in particular to a kind of method of continuous production pot galvanize color-painted steel strip.
[background technology]
Pot galvanize is current most widely used metal rust preventing method, and along with the develop rapidly of cold-rolled steel strip, the steel band continuous hot galvanizing has obtained large-scale development.Along with the development of society, there have the steel plate of outward appearance effect not only to require to be anticorrosion, and require attractive in appearancely, and therefore color bag coated steel sheet just arises at the historic moment, and obtains develop rapidly.But pot galvanize at present and coloured coating are production lines independently separately, and never the people want these two production lines are merged, and production line has following shortcoming but adopt independently:
A. need more utility appliance (for example Abrollhaspel, winder, kink, shears, welding machine etc.), so production line cost of investment height, and floor space is also big;
B. owing to be not direct color coating after the pot galvanize, so need oiling after the pot galvanize, and also need before the color coating to handle again;
C. owing to need batch between pot galvanize and the color coating and the uncoiling operation, therefore bigger to the infringement of steel plate alteration of form, strip shape quality is poor;
D. owing to be not direct color coating after the pot galvanize, therefore need carry out galvanized sheet and weld this unstable operation;
E. because steel band after the pot galvanize and the steel band before the color coating need to shear, therefore cause the waste of steel band;
F. total production run expense height.
[summary of the invention]
In order to address the above problem, the invention provides a kind of method of continuous production pot galvanize color-painted steel strip, it is incorporated into a production line with pot galvanize and coloured coating.
For realizing purpose of the present invention, the technical solution adopted in the present invention is: a kind of method of continuous production pot galvanize color-painted steel strip is provided, and it may further comprise the steps at least:
A. steel band enters the plating pretreatment stage, adopts acid wash to remove the ferric oxide of steel strip surface;
B. the steel band after the plating pre-treatment enters the solvent treatment stage, and this steel band enters solvent trough, coats solvent in steel strip surface, and is no longer oxidized to guarantee steel strip surface;
C. the steel band after solvent treatment enters the solvent baking stage, sends this steel band to stoving oven, the remaining moisture content oven dry of steel strip surface;
D. the steel band after the drying enters the pot galvanize stage, sends this steel band to the zinc pot, and the reaction of steel band and zinc liquid plates layer of even zinc liquid in steel strip surface in zinc liquid;
E. the steel band after zinc-plated enters the plating postcooling stage, sends this steel band to refrigerating unit it is cooled off;
F. enter chemical treatment stage through cooled steel band, this steel band is carried out chemical treatment;
G. the steel band after chemical treatment enters baking stage, with this steel band oven dry;
H. the steel band after the drying enters the rendering stage, sends this steel band to the rendering machine and primes;
I. the steel band behind rendering enters the baking stage, sends this steel band to roaster and toasts;
J. the steel band after baking enters essence and is coated with the stage, sends this steel band to essence and is coated with the machine overpainting;
K. the steel band after essence is coated with enters the baking stage, sends this steel band to roaster and toasts.
Further comprising the steps of before the step a:
A1. coil of strip is contained on the Abrollhaspel, makes coil of strip expand into steel band;
A2. if a last coil band launches then to enter step a3 fully, if after treating that a coil band launches fully, the portion end to end that two coils are rolled up pinches the welding machine welding respectively, thereby front and back two coils volume is welded together, realizes continuous production;
A3. steel band enters the kink bin stock stage, and steel band is fed into entry loop.
Further comprising the steps of after the step k:
K1. the steel band after baking enters the kink bin stock stage, sends this steel band to the outlet kink;
K2. the steel band after steel band comes out from the outlet kink enters shear stage, will deliver to shears from the steel band that the outlet kink comes out and shear;
K3. the steel band after shearing enters the rolling stage, and the steel band that has been coated with color layer is delivered to winder, is rolled into the finished product volume on request.
Is that independently production line is compared with traditional pot galvanize with coloured coating, and therefore the present invention can realize following advantage because pot galvanize and coloured coating are incorporated into a production line:
A. owing to reduced each utility appliance (for example Abrollhaspel, winder, kink, shears, welding machine etc.), so the whole production line cost of investment reduces approximately 30～40%, and floor space reduces 50～60%;
B. because directly instant color coating after the pot galvanize, so do not need oiling after the pot galvanize, do not need before the color coating to handle again yet;
C. since between pot galvanize and the color coating without batching and the uncoiling operation, therefore infringement reduces to the steel plate alteration of form, strip shape quality improves;
D. because directly color coating after the pot galvanize moves continuously, therefore need not carry out galvanized sheet and weld this unstable operation;
E. because steel band after the pot galvanize and the steel band before the color coating need not sheared, therefore can not cause the waste of steel band;
F. the production run expense reduces by 30～40%.
