Abstract
A forming stand for continuously forming a skelp material into a pipe, by pressure of spaced-apart forming rolls supported by spaced upper and lower shafts, the forming rolls having two portions, with one portion fixedly fitted on one side of its shaft, a sleeve slidably fitted to the other end of the shaft and fixedly secured to the sleeve and slidable with respect to the shaft; a bearing box for supporting one side of the associated shaft; a bearing box supporting the other side of the associated shaft through the sleeve; upper and lower stand supporting frames for supporting both of the bearing boxes to be movable in an axial direction; and supporting columns for supporting the stand supporting frames; the pipe-forming force is continuously measured and the forming operation is adjusted such that the measured value of pipe-forming force does not exceed a predetermined pipe-forming upper limit.
