PROBLEM TO BE SOLVED: To provide a method and a controller for controlling change of a mold width in a slab continuous casting facility which enable, even in the slab continuous casting facility performing fluid state adjustment of molten steel with impression of magnetic field, accurate measurement of inclination angles of short side walls of the mold during changing the width, and adjustment of the inclination angles by using the measurement information in real time. SOLUTION: In the method for controlling the change of the mold width in the slab continuous casting facility in which the moving quantity and the inclination angles in the short side walls of the mold are adjusted to change the mold width, the adjustment of the inclination angle in the short side walls of the mold is performed by using an optical fiber-loop type angle velocity sensor disposed at the short side walls.
