PURPOSE:To simplify a pretreating stage before enameling by immersing a degreased and dried steel sheet substrate for enameling in a nickel naphthenate soln., pulling up the substrate, drying and calcining it, coating enamel, and calcining it. CONSTITUTION:A degreased and dried steel sheet substrate for enameling is immersed in a nickel naphthenate soln., pulled up, dried, and calcined to form a thin nickel oxide layer on the surface of the substrate. Enamel is coated on the nickel oxide layer, and after diffusing and infiltrating the enamel into the layer, calcination is carried out.
