Optimal control of continuous steel poring and hot rolling as a flux

A classification of technological operations in steel pouring and hot rolling as one combine is given. An economic mathematical model of the processes of continuous pouring, slab heating and strip rolling is developed where one economic criterion is used for all these heterogenous processes; a strategy of optimal control of the flowchart proposed. The model and the strategy are implemented is a computer for control of a 2000 mm hot rolling mill. Modelling results are given.
