Abstract

To increase the productivity and to improve the quality of products, a mathematical model has been installed on two Sendzimir mills (LB1 and LB3) of ACESITA's plant based at Timóteo (MG). The physically-based model was developed to optimize the schedules for rolling stainless steel of the 300 and 400 series. Thanks to a versatile formalism for the parameterization, all the constraints of the process and products are taken into account to help the operators and to minimize the rolling time. It was chosen an architecture based on a remote personal computer loaded with the mathematical model and working with the operating system Windows NT. An important work was done for the safety of this industrial application. The user interface was developed to give all the necessary tools to make pass schedule calculations, to analyze and to optimize them, with the goal to improve the quality and the productivity of the mill. The mathematical model also has the opportunity to build a database with measures from the mill. Close attention has been paid to the comparison of theoretical and experimental data to ensure reliable calculations of new schedules.
