Disclosed is a method and apparatus for spray application of a monolithic refractory material, designed to add water to a powder material and knead the powder material during feeding. In the method and apparatus, a primary water injector 7 is arranged in a feed hose 5 extending from a spray-material supply device 1 to a distal spray nozzle 4, and a secondary water injector 8 is arranged in the feed hose at a position just before the distal spray nozzle 4. The primary water injector 7 is arranged on an upstream side of the secondary water injector 8 with a given distance therebetween. 10 to 50 mass%, preferably 15 to 40 mass%, of application water on the basis of the total application water required for the spray application is added from the primary water injector together with compression air in the form of water particles having an average particle size of 100 µm or less, to evenly wet a spray material during feeding to the extent capable of preventing the spray material from being slurried. Then, the remaining application water is injected from the secondary water injector together with compression air. The spray application method and apparatus of the present invention can achieve a high kneading effect by a low amount of application water while improving operational efficiency. |
