摘要： A process for producing an enamelling steel sheet which comprises tapping molten steel with manganese content not more than 0.40%, lowering the carbon content in the molten steel to not more than 0.01%, adding titanium to the molten steel in an amount enough to obtain a titanium content between 0.01 and 0.3%, preferably between 0.03 and 0.1%, and also adding one or more of rare earth elements such as lanthanum, cerium, neodymium, praseodymium, and samarium (hereinafter called Rem) in total amount between 0.01 and 0.15%, preferably 0.02 and 0.12%, casting the molten steel into ingot or slab, hot rolling and then cold rolling the ingot or slab preferably at a cold rolling rate between 30 and 90% and then annealing the steel sheet.
