Abstract

PURPOSE:To diminish the fish tail to be generated by an edging pass, by forming the cross section of head and rear ends of a plate material into a convex shape with tapered both side edges, and then, by applying an edging pass and next a broadside rolling pass in order to finish the plate material into a rectangular cross section. CONSTITUTION:On the way of transportation of a plate material 1 before being fed to an edging mill, the head end of the plate material 1 at first and its rear end next are pressed at its side edges in the direction of thickness by forming dies 3, 3' of a forming machine D; hereby, the head end and rear end of the material 1 are formed into a shape having a uniform cross section B following to a cross section altering part C. Thus prepared plate material 1 is subjected to repeated edging works to be applied by vertical rolls 2 of an edging mill E; hereby, the breadth of the material 1 is finished to a product breadth. In this material 1, a fish tail is generated as a result of said works, and the transverse thickness distribution is made convex at the middle zone of the material 1; the material 1 is then subjected to a broadside rolling pass with a light draft percentage to be applied by horizontal rolls 2' of a horizontal mill F, and is finished into a rectangular cross section; hereby, the fish tail is diminished.
