Abstract
Provided are hot rolling equipment and a hot rolling method for precisely controlling the meandering and plate shape of a steel strip, thereby making it possible to prevent tail end squeezing of the steel strip. Hot rolling equipment () for this purpose, for sequentially passing a steel strip () through rolling machines () and thereby rolling the steel strip (), wherein a plurality of split rolls () capable of contacting the steel strip () is provided between the rolling machines (), and, when the split rolls () contact the steel strip (), detection torques (Td, Tw) acting on the left and right ends of the split rolls () are detected by torque detectors (), the reduction leveling of the rolling machines () being adjusted on the basis of the detected detection torques (Td, Tw) to control the meandering and plate shape of the steel strip ().
