Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for repairing a taphole in a converter which can obtain a repairing effect excellent in durability in a short period of time. SOLUTION: In the method for repairing the taphole 2 in the converter, a cylindrical repairing refractory 7 having a molten steel passage is inserted and fixed into the taphole 2 of the converter. The repairing refractory 7 is composed of a plurality of separated pieces 71,72 separated with the faces inclined to the longitudinal axis of the cylindrical repairing refractory 7. When these pieces are inserted into the taphole 2, respective inclined faces of the separated pieces 71,72 are made to abut on each other and fixed. COPYRIGHT: (C)2005,JPO&NCIPI
