Intelligent Control System of BOF Steelmaking
0n the basis of analyzing BOF steelmaking characteristics, a prediction model and control model based on neural network were established. Taking endpoint temperature and endpoint carbon content as control target, oxygen-blown volume and added coolant were calculated, then endpoint control of convert steelmaking was realized. Simulation results show that the simulation result of endpoint temperature and carbon content are satisfying and control strategy is very effective. The application results demonstrate the efficiency of the method.
Research and Application on Compound Intelligent Control System for Coke Oven Heating
Coke oven is a complex object with the characteristics of long time-delay,strong non-linearity,multivariable coupling and parameters changeability.The mean flue temperature is affected by many factors and traditional control method is not satisfactory.A control principle of combining the intermittent heating control with heating gas flow adjustment was proposed and the intelligent control methods,namely fuzzy control and neural network,were adopted to establish intelligent control strategy and model of coke oven heating,which combines two feedback control,one feedforward control and intelligent control.According to coking mechanism,a feedforward model was built for heat supply,and carbonization index CI feedback model was proposed to control coking.A flue temperature soft measurement model based on linear regression and RBF neural network was built to establish temperature feedback control.Intelligent control methods were used to control heating time and heating gas flow.Finally a compound intelligent control system of coke oven was developed.The practical operation indicated that the system can realize intelligent control of coke oven,stabilize production,improve effectively coke quality and decrease energy consumption.
