OPTIMIZATION AND MONITORING OF PROCESS-CO NTROL IN THE CONTINUOUS-CASTING OF STEEL

Presentation of a three-dimensional nonstationary mathematical model f or the calculation of temperature distribution in the strand of a slab continuous caster. Adaptation of the model to the specific plant cond itions. Determination of the optimum model parameters with the aid of an inverse model on the basis of measured surface temperatures. Optimi zation of the plant secondary cooling system by application of the mat hematical model. Elaboration of spray schedules for the optimization o f surface temperatures in terms of crack formation. On-line monitoring of the thermal condition of the strand. Preparatory steps for the inc lusion of the resulting data in the process control. Production increa se and quality assurance.
