摘要: A method for operating a blast furnace, comprising the steps: charging iron ores and cokes through a furnace top into the blast furnace; blowing in gas containing 40 vol. % or more oxygen together with pulverized coal through tuyeres into the blast furnance; and controlling a fuel ratio within a range of 500 to 930 kg/ton., molten pig iron and still a ratio of the pulverized coal blown in through the tuyeres within a range satisfying the formula: ##EQU1## molten pig iron, where X represents a fuel ratio. Through blown-in inlets set in the furnace shaft, preheating gas is blown in to preheat burdens. The cokes charged into the blast furnace are cokes of low strength having a drum index of DI.sub.15.sup.30 of 80 to 90% .

摘要: A method for operating a blast furnace by inferring the operating conditions in the blast furnace, on the basis of data supplied from sensors 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 and various processing units provided within the computer. Prior to the inference, the data from the sensors are processed by a large-scale computer and various processing units provided within the large-scale computer. The inference is performed by using certainty factor values, thereby making diagnosis of slip, hanging and channeling.

摘要: A method for controlling heat conditions in a blast furnace wherein the heat conditions are inferred and judged in comparison of data output from sensor means provided for the blast furnace with knowledge base means formed by accumulated experience on the operation of the blast furnace. The heat conditions are inferred and judged from levels of heat conditions and from levels of transition of heat conditions, wherein data regarding molten metal temperature and those regarding sensors are used. The inference and judgement are carried out by inference engine means included in a small-scale computer.
