Abstract

The temperature profile of material being formed in the rolling mill train is simulated before the actual rolling- or cooling process. Several simulation computations are made, in which simulation parameters are varied to adjust the required cooling process, e.g. for shock cooling or cooling with minimal temperature differences. Parameters obtained by simulation are combined with actual values measured before and after the cooling path, and are used to control the process. An Independent claim is included for equipment carrying out the process. This includes a simulator (1), technological data unit (2), process data unit (3), control unit (4) and process regulation unit (5).
