METHOD OF MANUFACTURING ENAMELING STEEL SHEET EXCELLENT IN ADHESIVENESS

WIPO Patent Application WO/1991/001390

A1

A method of imparting excellent adhesiveness to an enameling steel sheet made from a slab produced through continuous casting, in which the surface of the steel sheet is activated by pickling in the course of manufacturing it, particularly after recrystallization and annealing and prior to molding, so that, even when using an enamel not requiring sulfuric acid pickling or Ni flushing, no defects will develop in enamel such as fishscaling, blister, and black speck.
