Basis for all colculations of steel properties using metallurgical modelling is the fact that the mechanical properties are determined unambiguously by the microstructure and the chemical composition of the hot strip. Therefore it is the task of metallurgical modelling to describe the metallurgical processes which are involved in the evolution of microstructure during the rolling and cooling of hot strip as precise as possible. From the calculated microstructural parameters of the finished product in final algorithms the mechanical properties are predicted. For the production of hot strip in a hot rolling mill at TKS such a simulation system has been developed and named TKS‐StripCam. It is based mainly on semi‐physical models adapted to results from laboratory measurements. Using production parameters such as rolling schedule or as cooling conditions as well as the chemical composition as input parameters TKS‐StripCam allows one to the calculate the microstructure and to derive from this e.g. yield strength, tensile strength, elongation to fracture with sufficient precision. The principles of TKS‐StripCam will be presented. Some applications of this metallurgical simulation system with offline use in the office and online use in a hot rolling mill will be demonstrated.
