This report describes the development of an on-line adaptive time optimal scheduling system for Sendzimir mills. The software required to calculate the time optimal schedules is detailed and the data required for optimization are specified. The system developed ensures that the calculated schedules respect the constraints required for quality strip production whilst maximizing the production capacity of the mill. An investigation of austenitic stainless steel yield stress has been performed using both compressive and tensile testing techniques. An empirical model relating rolling torque to pass descriptor variables has been developed. This model has been applied to data obtained from a production Sendzimir mill using torque telemetry techniques. A method of sensing the strain induced in the Sendzimir mill housing has been investigated and a complex relation between strain, roll separating force and roll stack geometry has been observed.
