A blast furnace operation control expert system (BAISYS) making use of artificial intelligence (Al) was developed and applied to the commercial operation of Fukuyama No. 5 blast furnace.
BAISYS gathers real-time information from numerous sensors installed on the blast furnace, and by using both this information and knowledge base in Al processor, which consists of knowledge and experience of operaters and engineers (experts), inference and judgement concerning furnace condition are performed and the optimum action is indicated.
The abnormal furnace condition diagnosis expert system, one of the two sub-system in BAISYS, predicts the probability of channeling and slip every two minutes and provides the forecast and action. The furnace heat control expert system, the other sub-system which is designed to constantly control the furnace heat level represented by the hot metal temperature, executes inference every 20 minutes.
This system is very effective for the stable operation of blast furnace.
