METHOD FOR SPRAYING REFRACTORY AND REFRACTORY SPRAYING MATERIAL

PROBLEM TO BE SOLVED: To provide a method for spraying a refractory by which the peeling and damage to a spray executed material is prevented and the deterioration of fluidity of a spraying material is prevented and to obtain the refractory spraying material. SOLUTION: This method for spraying a refractory comprises providing the composition of a refractory aggregate of the spraying material comprising 1-15 wt.% of agalmatolite and 1-30 wt.% of silicon carbide in the method for adding a quick setting agent to the spraying material obtained by adding execution water and previously preparing the resultant mixture into a slurry state in a nozzle part and spraying the prepared spraying material. Furthermore, the refractory spraying material is preferably obtained by mixing the quick setting agent with a refractory fine powder, adding the quick setting agent in the mixed state to the spraying material in the nozzle or a forced feeding pipe or adding the quick setting agent to the spraying material obtained by adding execution water and previously preparing the resultant mixture into the slurry state, further adding the quick setting agent thereto in the nozzle or the forced feeding pipe and used for spraying. In the refractory spraying material, the composition of the refractory aggregate of the spraying material comprises 1-15 wt.% of the agalmatolite and 1-30 wt.% of silicon carbide.
