AI Technical Summary
The prior art requires additional processing steps and chemical reagents when printing patterns or patterns on the surface of steel plates, resulting in high costs and environmental risks, while potentially reducing the mechanical properties of the material.
By controlling the difference in average surface roughness of the steel plate surface, the pattern effect is achieved using visual color aberration without the need for additional chemical reagents or complicated processing processes. The specific method includes cold rolling and annealing of the hot-rolled steel plate, and then flattening with patterned rolls, with the roll surface having a region of different average surface roughness.
It realizes the metallic gloss effect and mechanical properties while forming patterns on the surface of the steel plate, reduces processing costs and environmental protection risks, and improves the stamping and forming performance of the steel plate.
