Abstract
PURPOSE:To virtually eliminate tapping closure failure accident that occurs frequently by repairing the contact parts etc. of the mud gun near the tap hole of a blast furnace by means of amorphous refractory materials then piercing a tap hole down to required depth and force-feeding mud into said tap hole by means of the mud gun. CONSTITUTION:The contact parts 2 of the mud gun 11 near the tap hole 5 of a blast furnace and their neighborhood are repaired by amorphous refractory materials to form repaired parts 3, 3, after which the tap hole 5 are pierced 8 down to the depth at which the molten iron near the inside of blast furnace does not flow out. Thence, mud material 10 is force-fed by the mud gun 11. As a result, the soft mud material 10 for closing the tap hole 5 infilters the repaired parts of the hole 5 and their neighborhood, thereby preventing the occurrence of cracking at the second and subsequent piercing of the tap hole and virtually eliminte the closure failure accident of the hole 5 after tapping.
