Abstract

PURPOSE:To prevent precipitation of graphite on the surface of a colled steel plate during annealing by electrocleaning the plate in an aq. soln. of a alkali contg. sulfur cpds. and a sequestering agent or coating the plate with a soln. contg. the sulfur cpds. and sequentering agent before annealing the plate.
