Abstract:
    a method for operating a blast furnace by inferring the operating conditions in the blast furnace, on the basis of data supplied from sensors (11) set in the blast furnace and also on the basis of the knowledge base formed by experience on the operation of the furnace by a small-scale computer (20) and various processing units (21, 22, 23) provided within the computer. Prior to the inference, the data from the sensors are processed by a large-scale computer (10) and various processing units (12, 13, 14, 15) provided within the large-scale computer. The inference is performed by using certainty factor values, thereby making diagnosis of slip, hanging and channeling.
