Model of Layer-by-Layer Cooling Trajectory in Rolled Products by TMCP

The paper describes some aspects of a scientific and research project dedicated to mechanical property prediction in plates for pipe production rolled at PJSC MMK 5000 Mill. The prediction is based on billet thermal state modelling by thermo-mechanical control process (TMCP) of rolling and subsequent cooling. The central focus of the modelling is the calculation of billet layer-by-layer cooling trajectory. The paper presents some results of model verification by test rolling.
