ROLL SFEED AND ROLL GAP MODELLING - A CASE STUDY FOR AN EXPERIMENTAL ROLLING MILL

摘要

In this paper the detailed procedure of model development for a laboratory scale rolling mill (the Hille mill) is given. The main framework of the roll speed and gap model is based on the classic Newton motion equation, with the critical model parameters, such as the inertia of the different rotational parts, the frictions, the stiffness, etc, to be determined by different approaches ranging from analytical to experimental approaches as well as know-how. The developed models have been incorporated into a mill simulation package, and computer simulation results show a good agreement with the actual rolling process. The final goal of the models will be two-fold: to generate a decision support for the upgrading and modernisation of the Hille mill, and to develop advanced model-based rolling control strategies.
