Title: Rolling mill for forming section having flange
Inventor: MIZUNUMA SUSUMU
IPC: B21B27/02
Filed: 1984-03-30
Abstract: PURPOSE:To obtain the titled mill capable of changing the web dimension of a section by width-spreading rolling the flange inner-face of a section material, by arranging four overhung rolls having the same shapes horizontally and vertically symmetrically in the plane vertical to a pass line, in rolling a bisymmetrical section-material. CONSTITUTION:A section material 1 having a flange of H-shape, I-shape, or channel-shape, etc. is rolled in the interflange-1a-width spreading direction by four driven or nondriven overhung rolls 2, 2', 3, 3' of the same shapes, arranged vertically and horizontally symmetrically to have vertical axes respectively, in the plane A-A vertical to a pass line PL. The width and thickness of the web part of section I can be freely changed by spreading the distance between the overhung axes, and the application range of dimensions is enlarged because of the overhung rolls. Further, the right and left overhung rolls can be formed into taper ones by slanting their axes, or reforming rolls can be arranged at the outsides of both sides of section-material or at the front and back of the PL line.
