| Popis: | The mathematical model of hot-rolled coil rolling at the Steckel mill (Ferriera Valsider SpA) has been thoroughly investigated in the paper. There has been made a verification of the developed model to use it for the rolling technology design. The influence of the stand stiffness has also been taken into account. When simulating rolling temperature conditions, an average error was within the range from 8.27 to 9.11% at the mill 3170 and from 0.003% to-0.92% at the mill 1780. When simulating rolling force, an average error was within the range from 0.5% to 5.7% at the mill 3170 and from-4.89 to 6.59% at the mill 1780. The equation has been obtained, and the comparison of calculated stands stiffness has been made at the mill 3170 and 1780.There has been determined influence on the actual measurement of the pre-treatment temperature for the feed processing by descaler, which results in significant errors compared to the calculation results. |
