摘要： PURPOSE:To allow preservation over a long period of time and to improve density and corrosion resistance by constituting the above refractories of a wet refractory compsn. part which is preliminarily kneaded with moisture of a part of the moisture content for application and a soln. part contg. the moisture of the remaining part and a binder part. CONSTITUTION:The wet refractory compsn. part is obtd. by preliminarily kneading 95 to 70 pts.wt. (hereafter pts.) refractory aggregate (e.g.: electromelting alumina, 5 to 30 parts refractory superfine powder (e.g.: fine powder silica) having =2 kinds of dispersants selected form alkaline metal phosphate and alkaline metal polyphosphate, and 0.01 to 1 pt. one or >=2 kinds of wetting agents selected from polymer nonionic activators composed of polyoxyethylene glycol and polyoxyethylene polyoxypropylene glycol ether component with the moisture of 1/5 to 3/4 moisture content for application. The soln. part is obtd. by dissolving 1 to 50wt.% binder (e.g.: sodium silicate) with the water of the remaining part of the moisture content for application. The above-mentioned compsn. part is force fed to a spraying gun and is sprayed by the spraying nozzle while the above-mentioned soln. part is added thereto.

摘要： PURPOSE:To obtain a spray coating material which hardly generates explosive fracture as against rapidly rising temp. at the time of drying and has high strength and high corrosion resistance by compounding a specific refractory compsn., water of the remaining volume of the water for coating and a setting agent. CONSTITUTION:The title castable refractories for spray coating is used in the spray coating method consisting in prekneading the castable refractories with the water of 1/5-3/4 the volume of the water for coating, force-feeding the kneaded matter obtd. in such a manner by a spray gun and adding the remaining volume of the water for coating in a spray nozzle. Said castable refractories consist of the refractory compsn. part consisting of 94-70pts.wt. refractory aggregate, 5-29pts.wt. superfine refractory powder having =1 kinds of alkali metal phosphate and alkali metal polyphosphoric acid and the soln. part consisting of the water of the remaining volume of the water for spraying added by the spray nozzle and the setting agent.
