WET REFRACTORY MATERIAL MANUFACTURING METHOD, WET REFRACTORY MATERIAL MANUFACTURING APPARATUS AND WET REFRACTORY MATERIAL SPRAYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a wet refractory material low in mass and high in adhesion strength and heat insulating properties by uniformly kneading refractory materials largely different in specific gravity, an apparatus for manufacturing the wet refractory material and a wet refractory material spraying device.;SOLUTION: In the method for manufacturing the wet refractory material 22, water 19 and a mixing agent 20 are charged in a wet mixer 15 to be stirred and, after the elapse of a constant time t₂, a composite material 17 comprising lightweight aggregate 17a, cement 17b, a siliceous fine powder 17c and short fibers 17d is charged in the wet mixer 15 to be kneaded and, after the elapse of a constant time t₃, foamed particles 21 are charged in the wet mixer 15 to be kneaded.;COPYRIGHT: (C)2003,JPO
