Abstract

Goal: Mathematic model checking of the technological process of hot-rolled coils rolling at Ferriera Valsider SpA Steckel Mill. Method of doing research: The checking of the developed model was carried out to allow its applying for the rolling process design. The influence of the mill springe was taken into account. It was determined the influence over the actual temperature measuring of the previous transfer bar processing by means of water descaling that results in significant inaccuracies when further comparing to the calculation results. Value: The average inaccuracy when modelling the rolling temperature conditions at mill 3170 is from 8,27% to 9,11%, at mill 1780 is from 0,003% to -0,92%. The average inaccuracy when modelling the rolling force at mill 3170 is from 0,5% to 5,7%, at mill 1780 is from -4,89 to 6,59%.
