Zusammenfassung:	PROBLEM TO BE SOLVED: To provided a clogging material for a tap hole in a blast furnace which is capable of easily opening and forming a working body having excellent durability. SOLUTION: An opening work in actual operation is facilitated by blending soil like graphite having 150-0.1 μm particle diameter with a refractory raw material having an adjusted particle diameter to have the proportion of 1-10 wt.% to total weight and adding a carbon remaining organic compound in a prescribed proportion as a binder to properly suppress the progress of the sintering to prevent over-sintering, and also the corrosion resistance is improved by reducing the necessary quantity of the binder such as tar in the mixing, and the tapping time is prolonged by suppressing the rapid enlargement of the tap hole.
