A Cold Rolling Mill Model for Unwinding Diagnosis

A model is presented which describes the uncoiling process of a rolling mill in fault-less and in faulty situations. This model is implemented in the DYMOLA modelling and simulation environment. It is used for two purposes: first for the simulation of the unwinding process and second for model-based fault diagnosis. For the latter diagnostic task, a simplified model is derived. Results of the s...

High-tech for Thin Sheet Modernization of a Tandem Cold Rolling Mill at Arcelor Eisenhüttenstadt

Rolling mill simulator A new platform for testing, analysis and optimization of cold rolling mills

The cold rolling of flat metal products especially in tandem or multi-stand mills is a highly complex process where the product quality is influenced by various aspects. With the help of a hardware-in-the-loop simulator, the complete rolling process can be simulated and tested in real-time. This allows pre-commissioning and pre-optimizations before the actual commissioning work is done on the p...

Development of a Predictive Finite Element Model For Investigation of Phases Behavior After Cold Rolling Process

 One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...
