Abstract: A method for supplying rolling oil for cold rolling comprises the steps of: supplying emulsion rolling oil using a first rolling oil supply system supplying the emulsion rolling oil to a roll and a steel sheet in a recirculation mode and a second rolling oil supply system supplying the emulsion rolling oil to only the front and back surface of the steel sheet, wherein the emulsion rolling oil, which is added with an emulsifier of the same type and concentration with respect to the amount of oil as those of the emulsifier of the first supply system and controlled so that the average particle diameter of emulsion is larger than that of emulsion of the first supply system, is supplied from the second supply system; and joining the emulsion of the second supply system to the emulsion of the first supply system.
