Abstract

The manufacturing of the non-circular pipes made by reshaping process is becoming more and more important because of their utilizations as in different industries. In this work, a reshaping process is presented with cold rolling of a circular thick tube into a square cross section between four flat rolls in different passes. The influence of the amount of roll gap reduction in each pass on the final rolled product was investigated. Quantities such as separated force energy, wall thickness, and corner radius of the tube were observed and measured.
