PROBLEM TO BE SOLVED: To provide a method of spraying work capable of giving dense monolithic refractories having a high density, mechanical strength and corrosion resistance without such problems as environmental aggravation due to rebound loss, deterioration of the quality of works due to moisture content increase, cumbersomeness of sweeping operation, and much waste of remaining materials. SOLUTION: This method of monolithic refractory composition spraying work using a spray machine comprises as follows: an air-carried monolithic refractory composition 12 is incorporated, before a spray nozzle 5, with such amounts of water and compressed air 9 for the work as to afford enough workability to be castable via a watering 1, and a flocculant or shape retentive agent 11 is added to the resultant composition at the spray nozzle part followed by conducting the objective spraying work; wherein the monolithic refractory composition comprises a dispersant and the main component composed of a refractory aggregate with particle size adjusted to <=10 mm, ultrafine refractory particles <=10 μm in size, and, as the case may be, cement. |
