Slab curvature compensation in a hot rolling mill by means of fuzzy control
نویسندگان
چکیده
In the flat products steel industry, the hot rolling mill transforms the incoming slabs in a thin coil which then can be processed to obtain the final products. Thickness is reduced by pulling the plate between two parallel rolls while moving the upper work roll. The effect of uneven thickness at both sides can produce deviations in the longitudinal direction of the slab, which have to be manually compensated for an human operator. In this paper a multivariable control system and a fuzzy control system are described and compared. Results are illustrated with real data from ACERALIA STEEL CORPORATION.

متن کاملInvestigations into the Effect of Tension Between the Stands of the Finishing Mill on Width Control in a Hot Rolling Process
This paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. An analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. Wusatowski's model which is developed to give an account of spreading is specified and a similar model to...
