The purpose of the study was to determine adjustments in the mill casing in relation to lifting and speed; firstly when flutes, rollers, grades and temperatures are changed; and secondly, to correct the effects of wear and tear. The aim was to control more effectively the average dimensions of each slab by anticipating variations in the parameters involved in the process. The final goal was to build and install an on-site system of adjustment for the mill train at Nueves Maisons, which was chosen as a pilot. A computerized process model was developed which allowed interactions between different parameters to be quantified. The input of coefficients must be further studied in order to obtain more representative results. Due to the restructuring of Unimetal (at the beginning of 1993), which changed the production at Nueves Maisons from multiple products to more specialized ones (wire for concrete and wiredrawing), construction of the operative system was abandoned because its exploitation was limited. The methodology that was developed, however, was transferred to other Unimetal mill trains.
