Automatic coking control system

An automatic coking control system has been developed and commercialized. The system is aimed at the stabilization and optimization of coke-oven operation. For this purpose, a control algorithm has been developed to calculate an optimum heat pattern based on optimum control theory, and the experimentation has been run to test the algorithm by using a temperature field simulator. The system has already been installed at coke-oven batteries of Nippon Steel's works. >
