Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the schematic diagram of two groups of storing rollers.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
It is a kind of can continuous production anti-finger print steel plate processing method, including：
（1）Substrate sheet prepares：Coil of strip uncoiling → aligning → shearing → welding → pre- degreasing degreasing；
（2）The step of preceding storing；
（3）Pre-electroplating treatment：Pickling → electrolytic cleaned → washing → pickling → washing；
（4）Plating and post processing：An iron plating → time electrogalvanizing → second time electroplating zinc → electrogalvanizing → pickling → washing three times；
（5）Fingerprint-resistant coating is applied through roll coater, and is dried at 120 DEG C, then anti-finger print steel plate is obtained after wind cools down；
（6）The step of storing afterwards；
（7）Wound after quality inspection, oiling.
Above-mentioned steps（1）In the both ends of weld seam are sheared by width notcher after welding, to avoid to rear machine
Scrape, pre- degreasing degreasing uses sodium hydroxide solution of the concentration for 10%-15%.
Step（2）And step（7）Storing is carried out by two groups of storing rollers, as shown in figure 1, every group of storing roller is quiet including one
Roller 1 and one moves roller 2, and two quiet rollers are in side, and for two dynamic rollers in opposite side, steel plate is S-shaped to sequentially pass through quiet roller → dynamic roller → quiet
Roller → dynamic roller sequentially passes through dynamic roller → quiet roller → dynamic roller → quiet roller, and forward and backward storing can ensure the storage for having more than 200m, and
Movement by moving roller can increase/reduce it the distance between with quiet roller, before coil of strip uncoiling after feeding and winding between blanking
In gap, the continuous production of anti-finger print steel plate can be ensured by adjusting dynamic the distance between roller and quiet roller.
If being provided with several groups of storing rollers to reduce the floor space of factory building, but storing roller is more more, and steel plate is defeated
Steering when sending is more, then easily causes steel plate to shift and rectified a deviation, it is necessary to be set in each turning point, is not only added to
This, and if have small skew in each turning point, after processing the phase can just be found, then the adjustment of the skew needs
Long period, influence to produce, step（2）And step（7）It is middle to use two groups of storing rollers to be set to be optimal.
Step（3）And step（4）In pickling use sulfuric acid solution of the concentration for 6%-10%, electrolytic cleaned uses Yixing
