A plastometric research on a torsion plastometer enables to carry out a physical simulation of forming in a wide range of deformation conditions. Two low-carbon microalloyed steel samples with different ratio of carbon, or Ceq respectively, were subjects to a simulation of structurally controlled rolling. In this way, it is possible to compare directly the values of deformation stress gained whi[...]

The laboratory rolling mill TANDEM was equipped with a pair of the high-speed temperature scanners LANDSCAN, enabling the accurate computer recording of surface temperatures of the rolling stocks with relatively small dimensions and the high speed of movement. By means of the used software, the task was managed, consisting in the on-line computing and displaying the maximum value of the tempera[...]
