PURPOSE: A method for predicting the temperature variation of molten steel in a blast furnace is provided to accurately determine how the temperature of the molten steel goes according to the quality variation of cokes. CONSTITUTION: A method for predicting the temperature variation of molten steel in a blast furnace is as follows; a step for taking a charged material sample of a winnowing fan in the blast furnace; a step for calculating the diameter variation of cokes in the winnowing fan by comparing the diameter of the cokes contained in the charged material sample and the diameter of the cokes before being charged into the blast furnace; and a step for producing the heat estimated index of the blast furnace by producing a relation between the diameter variation of the cokes and the cold strength of the cokes and a relation between the diameter of the cokes and the hot strength of the cokes. [Reference numerals] (AA) Estimated index of coke furnace heat (-); (BB) Molten steel temperature(°C); (CC) February; (DD) March; (EE) April; (FF) May; (GG) June; (HH) July; (II) (month)
