he production of hot strip at conventional Hot Strip Mills is divided in individual process steps,
starting from reheating, rolling at roughing mill and finishing mill, strip cooling at run out table and coiling. All the process steps run in principle one after the other and independently. In this way, each individual processing step is optimized in isolation while adhering to the individual set values. This conventional procedure does not attain the best overall result as the optimization of one
process step may have adverse consequences for another process step, i.e. the interaction between them is neglected. The Integrated Temperature Model (ITM) of SMS group completely remedies these disadvantages. By using the temperature setpoints from the traditional strategy an integrated, higher-level temperature profile from the furnace to the coiler is determined. This profile is updated cy-
