A high-quality surface of the lower plate surface residual pickling method

Low surface present invention relates to a high-quality board process for pickling residues, includes the following steps: unwinding uncoiler; straightening machine of the strip surface oxides crushed release; strip pickling; pickled strip into mechanical polishing means mechanical polishing the surface; after polishing strip into the mechanical cleaning means remove surface residue remaining board; then strip enters the mill is subjected to a surface roughness uniform finishing treatment; volume coiler coiling. By this technical solution, a mechanical polishing means on the strip surface mechanically polished surface repair, excellent surface quality; mechanical deck 2 Clear Clear plate surface residual acid residue means to enhance the corrosion resistance of the product; 3 by mechanical residue of formula board cleaning rinsing device to achieve normal, reduced consumption of production; strip 4 enters the mill temperature is low, it will help to ensure the quality of the final product shape.
