Title:

MONOLITHIC REFRACTORY SPRAY APPLICATION METHOD, AND SPRAY MATERIAL USED THEREIN

Document Type and Number:

WIPO Patent Application WO/2019/181505

Kind Code:

A1

Abstract:

Provided is a method for the spray application of a monolithic refractory in which application water is injected from a water injector 7, which is provided to a material-conveying tube 5 which extends from a material-supplying unit 1 to a distal-end spray nozzle 4, into a spray material conveyed inside the material-conveying tube, wherein, in order to improve the stability of said spray application, either: the ratio (flow rate of application water conveyance gas/flow rate of spray material conveyance gas) of the flow rate (Nm3/min) of an application water conveyance gas for conveying the application water introduced by the water injector 7, to the flow rate (Nm3/min) of a spray material conveyance gas for conveying the spray material, is 0.07 to 2, inclusive, and, the spray material has a degree of compression of 32% or less; or, the ratio (flow rate of application water conveyance gas/application water volume) of the flow rate (Nm3/min) of application water conveyance gas for conveying the application water introduced by the water injector 7, to the amount of the application water (m3/min), is 100 to 1000, inclusive.
