Abstract
Pressure is exerted on the interior of casting rolls with a negative crown so that the rolls may maintain a true cylindrical surface without any crown when the continuous casting operation is initiated. When the cylindrical surface of the rolls is heated by molten metal as the continuous casting operation continues, the interior pressure of the rolls is decreased, whereby the rolls may maintain a true cylindrical surface without any crown.
