FEM - Opis:
- The study proposed the model of "guide mark" defects formation on the internal surface of pipes, produced on PRM mills of PRP–140. The research of pipe forming at plug rolling mill with stub mandrel has been carried out; regularities of the dimens ionless parameters characterizing the deformation of the gap release, depending on the reduction ratio, were determined. The model of "guide mark" defect formation on the internal surface of the pipe has been proposed. This allows for lesser wall thickness variation o f rough tubes. It has been shown that, when using dioctahedral pass designs in comparison with hexagonal pass designs the proportion of displaced volume along the pipe axis is greater but the value is lower; thereby, the risk of "guide mark" defect forming is red uced.
