Abstract
A rolling installation comprises a continuous casting machine, and a light thickness-reduction rolling mill, a width-reduction rolling mill and a thickness-reduction rolling mill which are arranged downstream of the continuous casting machine. The light thickness-reduction rolling mill is driven with a power lower than that required for thickness-reduction rolling by the light thickness-reduction rolling mill. The power deficiency is supplied to the light thickness-reduction rolling mill by the thickness-reduction rolling mill through the cast strip. As a result, a longitudinal tension is applied to the cast strip passing through the width-reduction rolling mill, thereby preventing the cast strip from being buckled and deformed at the width-reduction rolling.
