    摘要: A method for producing a molten iron in a blast furnace comprises the steps of: preparing an optical fiber covered with a metallic tube; measuring a temperature of the molten iron flow discharged from a tap hole of the blast furnace by means of making use of a metallic tube covered by the optical fiber to obtain an information of the temperature of the molten iron; and controlling a heat conditions of the blast furnace, based on the obtained information of the temperature of the molten iron. Controlling a heat conditions is achieved by using a heat conditions estimation model, and by inferring a level and a transition of the heat conditions in the furnace.

    摘要: A synthetic resin fuel for stable production of pig iron in a blast furnace. It is in the form of cylindrical pellets, each measuring X mm in thickness and Y mm in diameter, with X and Y satisfying the three expressions of 3.0≦X≦10, 2≦Y≦20, and Y/X≧1.5. The cylindrical pellets are produced by melting a resin, solidifying the melt, and cutting the solidified product. The cylindrical pellets should preferably contain more than 0.05 wt % of water. A process for producing pig iron in a blast furnace by blowing a synthetic resin fuel into a blast furnace through tuyeres, wherein said synthetic resin fuel is in the form of cylindrical pellets, each measuring X mm in thickness and Y mm in diameter, with X and Y satisfying the above-mentioned three expressions. The cylindrical pellets should preferably have a size distribution such that those having a diameter within ±20 % of the average diameter account for more than 70 wt %.
