Embodiment Construction
[0026] Depend on figure 1 , figure 2 It can be seen that the refractory castable 2 is poured into the mud sleeve frame 1 of the integral pouring mud sleeve of the iron gate fixed on the blast furnace shell 10 . The mud sleeve frame 1 is a box-shaped body, and the inside of the box plate 3 is provided with dovetail-shaped consolidation pendants 4 all over. The rear end of the mud jacket frame 1 is welded on the blast furnace shell 10 and surrounds the iron mouth; The module 7 is fixed on the formwork 6 and is aligned with the center of the iron hole. An iron pipe is set between the module 7 and the center of the iron hole, and the diameter of the iron pipe is equivalent to the diameter of the iron hole. Clay casing frame 1 is filled with castable 2, and after castable 2 is baked and consolidated, the iron pipe is melted, leaving a gap to drill iron channel 8.
[0027] The mud sleeve frame 1 is a steel plate structure, which can be used repeatedly for a long time; after the ...
