摘要
A dry refractory mix and a method for apply the dry refractory mix to a surface. One aspect of the invention utilizes gunning mixes without cement. The dry refractory mix also may include a setting agent that is homogeneously blended with the refractory mix. In operation, when used with pneumatic systems, dry refractory material is fed into a hopper of a gunnite machine, introduced into an air flow, and conveyed by air through one or more hoses to a nozzle. A liquid binder is introduced into the air flow for mixing with the suspended dry refractory material at or before the nozzle. A fitting, such as a water ring with holes, may be used for injecting the binder into the air flow containing the dry refractory material. The mixed refractory/binder material is discharged through the nozzle for application to a surface.
