PROBLEM TO BE SOLVED: To provide a slab rolling method capable of effectively rolling a slab by surely performing 90-degree turning operation, and thereby shortening a time required for the 90-degree turning operation. SOLUTION: In final paths of rough rolling and broadside rolling for performing 90-degree turning operation after rolling, metal-out and/or metal-in signals are utilized, gravity location of a material to be rolled is determined, 90-degree turning operation is performed while conveying the material to be rolled, and rolling is performed.
