Surface characteristics of pickled sheet steel and their importance for the direct utilisation of the product
This work aimed to improve the surface finish of pickled sheet steel, by linking the characteristics of the incoming product and the pickling process with the surface characteristics of the outgoing product. It also examined the ways in which certain uses might be affected. "Black sheet metal", three categories of steel, the surface of the pickled product, picklability, overpickling, and the effects of pickling and rinsing conditions were analysed. Finally, suitability for oiling and phosphating the pickled hot-rolled sheet were investigated in relation to the observed characteristics. The influence of type and roughness was tested at pilot scale; despite superficial morphological variations, the phosphate layer obtained was comparable for each type. The corrosion test did not allow the steels to be distinguished from one another. The results obtained for hot-rolled sheet were identical to those for a reference sample of cold-rolled sheet.
