Abstract
This paper describes the model based control system of the sintering process.The control includes ignition control, sintering control and exhaustion control. Themathematical models are derived from basic models of physical and chemical processesand use directly and indirectly measured quantities from sintering strand. The controlsystem determines the optimal quantity of coke, volume of coke combustion air,preheating gas volume, combustion air for preheating and volume of exhausted gases.Values of these quantities are corrected according to the identified process state.Manipulated variable is the turbo-exhausters operating speed.
