Improvement in the manufacture of oriented grain steel sheet. The improvement relates to coating step of the sheet with annealing separators in order to obtain a complete purification of the steel from harmful components as well as the production, during the annealing step, of a continuous and adherent layer of glass film having the same and constant thickness on both surfaces of the steel sheet. …<??>The invention consists in that the coating of the sheet with said annealing separator is carried out from a suspension of annealing separator in a suspension medium having a non-aqueous base, preferably commercial ethyl alcohol containing limited and controlled amounts of water, using the continuously passing steel sheet as the cathode of an electrophoretic cell, the anodes being a couple of electrodes placed in, and near the free surface of, the bath, simmetrically with respect to the steel sheet. |
