Abstract

A method for making an enameled steel sheet includes the steps of spraying a slurry to form a slurry layer onto a surface of a substrate and firing the slurry layer. In this method, the slurry has a static surface tension of 50 dyne/cm or less and an apparent viscosity of 500 mPa·s that is measured with a model E viscometer at a rotation of 100 rpm. Alternatively, the method includes a step of spraying a slurry for forming an enamel layer onto a surface of a substrate, wherein the substrate is vibrated when the slurry is applied or when the slurry applied is still fluid.
