Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for estimating the maximum fluidity of a coal blend added with a caking additive to impact it a high-strength property appropriate for the application to the manufacture of coke for steel manufacturing, in particular, coke for metallurgical use. SOLUTION: This method is used for estimating the fluidity of a coal blend made by blending two or more kinds of original coal and adding the caking additive to the blend. A relational expression is found between the fluidity of a coal part only of the coal blend before the caking additive is added thereto and the increment of fluidity of the whole coal blend after the caking additive is added thereto. The fluidity of the coal blend after the caking additive is added thereto is estimated based on the obtained relational expression.
