| titleOfInvention | Hot repair method of blast furnace wall |
| abstract | (57) [Summary] [PROBLEMS] To provide a hot repair method for a blast furnace wall which can solve the problems of the dry spray method and the wet spray method. SOLUTION: This method is a method in which a blast furnace is shut down and a refractory is sprayed on a damaged portion of a furnace wall refractory inside the furnace to repair the refractory. 25 particles having a maximum particle size of 5.0 mm or less and 0.075 mm or less % To the refractory composition having a particle size composition of at least 2% by weight, water is added at a mass ratio of 2 to 15% with respect to the refractory composition, and a predetermined ratio of a dispersant is added to the refractory composition, and the mixture is uniformly kneaded in advance. . After pumping this slurry-like amorphous refractory to the nozzle, A hardening accelerator is added at the nozzle portion and sprayed together with a high-pressure gas onto a damaged portion of the blast furnace wall. [Effect] Since the refractory composition can be uniformly mixed, problems associated with the dry spraying method can be improved. Further, unlike the wet spraying method, the refractory kneaded material is fixed before spraying the blast furnace wall, and does not harden in the hose or the nozzle portion. |
