Abstract

A method of castable refractory spray application that enhances the effect of blending of spray material and water, thereby obtaining a finished article of low water content and high density, and that excels in operating efficiency. There is provided a method comprising equipping material delivery pipe (5) with primary water injector (7) disposed on its upstream side and secondary water injector (8) disposed on its downstream side so as to inject application water to a spray material from the two sites, wherein spray is performed causing the primary water injector (7) to inject application water in an amount of 10 to 50 mass% based on the total of application water while causing the secondary water injector (8) to inject the rest of application water to be applied, and wherein in at least injecting of application water from the primary water injector (7) into the material delivery pipe (5), the application water is injected into the material delivery pipe (5) so as to produce three or more water streams 30 DEG to 70 DEG inclined against the direction of material delivery and colliding with each other at nearly the center within the material delivery pipe (5), thereby generating atomized water of 100 μm or less average particle diameter.
