Abstract:

The paper introduces a concept for the reversing hot rolling of magnesium strip consisting of reheating of twin roll casted rough strip, carrying of coil from a furnace to coiler, setting down on mandrel, uncoiling, hot rolling and coiling of the magnesium strip. In the first stage the thermal models should be established. These models shall serve in the subsequent stages in order to support by developing of a roll gap model as well as model for forecasting the microstructure and material properties of the magnesium strip. Moreover, the paper represents the state of the concept development of the thermal models. Up to now, the following technological steps are implemented: reheating of the coil, transport of coil from furnace to the coiler, setting down on the mandrel and uncoiling of coil. The modelling of these models is worked out in three dimensions and are calculated numerically by using the Finite Element Method.
