Claims (1)
、かつ断熱材で作つた外筒により保護された爆発
穿孔器において、ノイマン成形爆薬を詰めた銅皿
を３個設け、各銅皿の中心軸線が上方の一点で交
わるようにある角度をもつて配置したことを特徴
とする高炉の残銑抜き工法に用いる爆発穿孔器。 In the explosion perforator, which is placed at the tip of a hole drilled in the bottom brick of a blast furnace and protected by an outer cylinder made of insulating material, three copper plates filled with Neumann-shaped explosives are placed in the center of each copper plate. An explosive perforator used in blast furnace residual pig iron extraction method, characterized by being arranged at a certain angle so that the axes intersect at one point above.
