In this work a mathematical model for estimation and optimization of the required consumption energy for the flat plate rolling of the group of Grade 0003 steel is presented. A design of experiments was performed. The key geometrical parameters namely, the thickness, the programmed plate width and the length are considered as independent parameters, in two levels of variation. The relation between these variables to the consumed rolling energy as a dependent changeable is described through the derived model of the plan matrix. A great number of data, collected in a four-year period were selected, filtered and processed statistically. Based on the model, graphs were obtained showing the dependence of the consumed rolling energy from the slab thickness and the programmed plate width and length. The results show that energy savings of about 11 percent can be achieved by operating the mill under optimal conditions.
