WET TYPE SPRAY-WORKING METHOD OF PREPARED UNSHAPED REFRACTORY

摘要

PROBLEM TO BE SOLVED: To provide a wet type spray-working method of prepared unshaped refractory making the worked material to the one having excellent durability and uniformity. ;SOLUTION: In the wet type spray-working method of prepared unshaped refractory, by which kneaded material consisting essentially of the prepared unshaped refractory and water and having the fluidity is pushed out in a transporting tube with a pump and after mixing a quick setting hardening agent at the tip part of the transporting part, this mixture is sprayed with compressed air onto the material to be sprayed, the mixture is sprayed at 30-60 cm distance from the spraying hole for mixture to the surface of the working material, with 100/1.5-100/4.0 flowing ratio (kg/Nm3) of the mixture and compressed air and ≥4.0 kg/cm2 spraying pressure of the compressed air.;COPYRIGHT: (C)2000,JPO
