Abstract
In a rolling method of rolling a material by front-stage rolling mill, a post-stage rolling mill and guiding rollers interposed therebetween. At first, a gap between the guiding rollers is set to a standard outer size of a standard material to be rolled by front-stage rolling rollers, and a standard embracing force formed by the guiding rollers at the gap is measured when the standard material passes therethrough. Then, a machine is operated, and a post outer size of a rolled material rolled by post-stage rolling rollers is measured. The post outer size of the rolled material is compared with a desired outer size of the rolled material. In case the post outer size of the material is smaller or greater than the desired outer size of the material, an embracing force of the guiding rollers during a rolling is compared with the standard embracing force. Then, the rollers are adjusted so that the post outer size of the material becomes the desired outer size.
