Abstract
The problems of computer simulation of the continuous tube rolling on FQM (fine quality mill) are formulated and solved to study the influence of technological factors on the shape change and the danger of metal fracture. The solution of the problems makes it possible to estimate the effect of the deviation of the rolling axes of the continuous mill and the extraction mill. The simulation results allowed us to formulate and propose technical solutions to minimize the probability of risk defect formation.
