Automatic Set-Up System for a Seamless Steel Tube Rolling Mill Line

Abstract

A computer system was developed to give technological support to a new seamless steel tube rolling mill. The system calculates the set-up and references values for all areas of the manufacturing process. During rolling, the more significant variables are measured and checked against theoretical references. Simultaneously, control algorithms estimate correction factors which need to be introduced.One of this algorithms is dedicated to the control of the axial tension in the continuous mandrel mill, which might have a negative influence on the dimensional quality of the tube.
