PURPOSE:To improve the width accuracy of a steel strip and to eliminate a trimming process by installing a three-point restriction type edger at the inlet and/or the outlet side of a final stand in a row of continuous rolling mills. CONSTITUTION:In installing a three-point restriction type edger 1 for performing a rolling reduction and a correction in the width direction as well as in the vertical thickness direction of a steel strip, in a strip rolling line; the edger 1 is disposed at least at the inelt or the outlet side of a final stand Fa, or are disposed at both sides according to circumstances, accordingly the number of sets of the edgers to be disposed is one or plural. In this way, the width accuracy of a strip (a) is remarkably improved to eliminate a trimming process, and an edge drop is remarkably reduced to improve yeild and production efficiency. |
