Abstract
A method of manufacturing a grain-oriented silicon steel sheet having excellent and uniform magnetic characteristics by improving the magnetic flux density of a silicon coil cold rolled to a thin thickness without increasing a Si content. The method comprises controlling steel sheet temperature along the rolling direction of a coil immediately downstream of the outlet roll bites of one or more rolling paths to about 15.degree. C. or less, and controlling the temperature of one or more of the rolling paths between about 150.degree. C. to about 350.degree. C.
