SMS group continues improving its hot rolling process models, prediction accuracy and technological controls performance efficiency. A new cross-functional model – meta model – takes an integrated temperature/microstructural approach. This takes process control to an entirely new level.
Hot rolling involves various consecutive process steps, each of which effect the mechanical properties of the product, for example - yield strength, tensile strength and low-temperature behavior. In addition, the result of the rolling process is influenced by the chemical composition of the steel and the temperature guidance during rolling. Established process control methods are able to minimize deviations from the target process parameters helping to avoid expensive claims, however rolling tests are often necessary, time-consuming and costly.
