Abstract
Superior blowing control system is required for stable operation and saving manpower in LD converter process. To investigate the possibility of future advances in blowing control system, a prototype expert system for blowing control has been developed.
This system is successful in applying the expert system to on-line real-time process control and applying the fuzzy reasoning to represent the ill-structured problem. As a test result, the high blowing controllability like a skilled operator has been achieved to prove the effectiveness of application of knowledge engineering to the blowing control.
