PURPOSE:To attach easily and quickly a cooling plate for repair to the wall of a blast furnace by suspending said plate by means of a wire rope via suspension rings, suspending the plate through the opening at the furnace top, pulling the leg part of the cooling plate toward the furnace wall by using a hook-pull metal inserted through the through- hole of the furnace wall and fixing the same to the shell. CONSTITUTION:The top end of a wire rope 8 is fastened to the suspension rings 45a, b attached to the upper part in the cylindrical part of a cooling plate 4 for repair and an attaching leg part 44 thereof and the cooling plate is suspended down to the prescribed position in the furnace through the opening at the furnace top by means of a freely liftable and horizontally turnable suspending device 6. A hook-pull metal 23 is then inserted into a through-hole 5 of the furnace wall for attaching the plate 4 punched preliminarily in an iron wall 1 and after the plate 4 is pulled toward a shell 1 side by said metal, a separately prepd. hook-pull metal 23a is hooked to the ring 45b of said leg part 44 by which the leg part 44 is pulled into said hole 5. The part 44 is fitted to the prescribed position and is then fixed to the shell 1 by means of required attaching fixtures, etc. by which the plate 4 is attached to the prescribed position. |
