For the efficient and stable blast furnace operation, the FLAG (Fine Lookout of Abnormal Gradient) system which can predict the unusual conditions at its earlier stage and direct the proper countermeasure, has been developed in NKK Fukuyama works. This system is included in the operation control computer system at No.2 blast furnace and has the following features. (1) Prediction indices ; these can detect the distinctive patterns of the sensor information which correspond to the process of the unusual states. (2) Usage of voice annunciator for the direction of the action ; It makes possible to deal with the abrupt change of the furnace condition. (3) Determination system for the threshold value of judgement ; It can maintain the prediction accuracy and can make it simple to introduce this system to the other blast furnace. This system has been contributing to stabilize the blast furnace operation.
