The purpose of this research project was to study and optimise operational practices, by means of appropriate mathematical models, in order to achieve "schedule-free" rolling. The results obtained are as follows: (i) operating practices for roll bending established by offline use of the model, resulting in greater control of strip profile (range now approximately 60 microns) enabling the production of strips dedicated to a particular use; (ii) adoption of high cambered back-up rolls and unification of work rolls grinding camber for rolling both steel and tin-plate strips; (iii) increase of the total length of each rolling programme with a related effect on the utilisation index of the mill (total length increase more than 30%); (iv) scheduling constraints have been reduced so that more strips of the same width can be rolled and the strip width can be varied stepwise at any stage during the rolling programme. Within the above limitations, it is possible to make the rolling "schedule-free", with the possibilty of increasing the percentage of hot charge rolling.
