Objetivo
This project is aimed at improvement in process control techniques affecting strip geometry (including gauge profile and shape) in hot rolling, and is particularly concerned with establishing the optimum mill operational performance, on the basis of:
- to establish a common monitor of operational performance against which each of the partners can assess progress in fulfilling objectives; - to measure and evaluate the influence of roll axis position tolerances and roll shifting on operational performance and strip quality; - to quantify and prioritise the factors causing operational instabilities and to establish the recommended operating practices and roll gap and roll stack tolerances to minimise operational problems and maximise strip tracking and to develop operational control parameters;
- to develop and calibrate a stack deflection off-line model which takes account of asymmetric aspects in particular and which includes a predictive capability for strip tracking;
- to carry out a comparison of the effect of alternative or additional methods of shape profile control on conventional roll bending and shifting; this will include self compensating back up rolls, CVC rolls and tapered work rolls.
The use of four different hot strip mills with differing strip geometry control systems will allow in-depth comparisons to be made.
