(57) [Abstract] (Modifications required) [Problem] To solve the difficulties of the dry spraying method and the wet spraying method, eliminate the need for kneading materials, do not obstruct the transfer pipe, and perform long-distance transfer. Providing a new spraying construction method that can be constructed and that construction refractories have high quality. An amorphous refractory composition (2) containing a refractory aggregate, a refractory powder, a binder, a dispersant, and a quick-setting agent is sent in a powder stream to an inside of a transport pipe (3). Convey while floating, add construction water in the middle of the conveying pipe 4 After that, the air is conveyed and blown through the blowing nozzle 5 to construct a furnace wall. |
