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.

摘要： PROBLEM TO BE SOLVED: To surely prevent the adhesion of a transport matter within a shoot by supporting a pair of impact rolls arranged substantially horizontally on the lower end of a pair of rocking arms rockably suspended in the middle of the falling course of the transport matter, and rotating at least one of the impact rolls. SOLUTION: A transport matter 3 carried out from an upstream belt conveyor 1 and falling is once collided to a pair of impact rolls 7 and stayed there, and then falls down through the clearance between the impact rolls 7 onto a downstream belt conveyor 2. Each impact roll 7 is rotatably supported at the free end of a rocking arm 6 rockably suspended, and at least one of the impact rolls 7 is rotated toward the opposite side of the opposed roll by a driving unit 8. According to a shoot having such a structure, the adhesion of the falling transport matter within the shoot can be surely prevented, and the scattering of particle masses of the transport matter can be prevented.

摘要： PURPOSE: To be able to suppress the stress corrosion cracking progress by using a support jig as a welding backing metal and spacer, and press injecting and filling thermal conductive heat resistant material in a gap formed between a repairing plate and a shell. CONSTITUTION: Fine ring-like lateral support jigs 2, 3 are welded fixedly to the upper and lower parts of the position to be repaired of a furnace shell. In order to repair, the lower ends of repairing plates 4, 4' circumferentially divided into a plurality are superposed on the lower jig 3, and welded fixedly. A predetermined gap is formed between the plates 4, 4' mounted via the jigs 3, 5 and a shell 1. That is, the lower ends of the plates 4, 4' and the side edges 4a, 4'b are welded fixedly to the jigs 3, 5. Thereafter, thermal conductive refractory is press injected from filler press injection inlets provided, in place, at the plates 4, 4'. Thus, the filler is press injected in the gap to discharge the air between the plate 4 and the shell 1 from the gap between the upper parts of the plates 4, 4' and the upper jig 2.
