摘要： PURPOSE:To repair a trough under condition of mutually cancelling out the load to the trough by laying a frame on the upper surface of vertical wall parts of the trough having almost U-shaped cross section, holding the inner and the outer surface of the vertical wall parts at the right and the left sides by a regulating means extended from the frame, and grinding the inner surface of the trough by a grinding means hung down from the frame. CONSTITUTION:A repairing device 10 is positioned above the refractory trough 1 for blast furnace having almost U-shaped cross section astride the leg parts 12 of a frame 11, laid on the upper surfaces 5, 6 of the vertical wall parts 3, 4 at the right and the left sides of the trough 1. The vertical wall parts 3, 4 at the right and the left sides are held from the inner and the outer surface by the trough outer surface regulating means 31 and a trough inner surface pushing means 41 extended from the frame 11, respectively. Successively, the bottom surface 2 and the inner surfaces of the vertical wall parts 3, 4 of the trough 1 are ground by using the grinding means 21 hung down from the frame 11. At this time, when the grinding means 21 pushes the vertical wall parts 3, 4, force in the reverse direction of this pushing force is generated through the frame 11 and a lever 33 and the reverse directional force to pushes the vertical wall part 3, 4, and in consequence, the action force with the grinding means 21 is cancelled out through the vertical wall parts 3, 4 and the frame 11, and an excess bending stress to the trough 1 is not developed.
