Abstract
Activation of steel sheet surface by subjecting to a pickling treatment after recrystallization annealing and before forming in the production steps of steel sheets for coating porcelain enameling. Continuously cast slabs are used as a starting steel, and the resulting sheet realizes an improved adhesion property, to porcelain glaze without causing fishscale, blistering and pinhole defects and the like even when using a glaze not requiring pickling with sulfuric acid, Ni flashing or the like as an enameling glaze.
