Abstract

PURPOSE:To obtain the cold rolled steel sheet from the rimmed steel of very low nitrogencontent with the denitrification treatment within a short period of time, by laminating the coil of the rimmed steel to be denitrified and the coil of the killed steel having a specified Al content and by carrying out the denitrification treatment in the gas stream consisting of hydrogen and nitrogen in a specified condition.
