不久以前,打开高炉出铁口的操作由下列两个程序来完成:采用电钻钻孔(由人工把它送往出铁口)和用考斯金锤把硬皮击穿;现在,在多数冶金厂中打开出铁口的操作由远距离控制的开口机来实现。开口机的结构基本上沿两个方向发展:1)采用象电动泥炮那样安装在立柱上的结构;2)开口机的导向梁的一端铰链式地固
Not long ago, the operation of opening the blast furnace taphole was accomplished by two procedures: drilling the drill (manually by sending it to the taphole) and crushing the crust with a Cowney hammer; now, in most metallurgy The operation of opening the taphole in the factory is realized by a long-distance controlled opening machine. The structure of the opening machine basically develops in two directions: 1) a structure mounted on the upright column like an electric mud gun; 2) one end of the guide beam of the opening machine is hingedly fixed
