Simulation and Analysis of the Three-Roll Seamless Steel Tubemaking Process

摘要

The three-roll rotary piercing process is modelled within the context of a total tubemaking plant because the three-roll process yields a higher quality tube with fewer surface defects and distortions. Two aspects are studied: the primary one is an experimental and theoretical analysis of the mechanics of the process using a scaled down, specially designed and constructed model piercing mill and analog clay material. The secondary one is a design of a system to control the process with a digital computer for the purpose of minimizing variations in wall thickness as well as optimizing various other system parameters.
