Comparative Analysis of Analytical and Graphical Upperbound Solutions for 4-High Reversing Aluminium Cold –Rolling Sheet Mill

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

a new rolling pressure model for an actual reversing cold rolling strip mill

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...

Improvement of thickness tolerances For a two-stand aluminium cold rolling mill

trol loops to compensate backup roll eccentricity and harmonic hardness variation allows a significant improvement in strip thickness performance. These measures were successfully implemented as an extension to an exist ing two-stand aluminium cold rolling mill. An essential quality characteristic in the cold rolling sector is the minimum thickness deviation that can be achieved at final gauge,...

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...

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...
