Refractory gunning mix is an unshaped refractory material used for gunning repair operations with a spray machine. It consists of refractory aggregates and powders of a certain particle size, binders, and additives. These additives may include accelerators, sintering aids, and mineralizers, etc., and they are generally thermosetting or air-hardening materials. · Easy to anchor, effectively preventing wall protrusion. · Simple and quick construction, requiring no templates or supports. · Strong overall performance and good sealing ability, preventing powder infiltration. · Few joints in masonry structure, effectively extending the life of furnace linings and reducing refractory material consumption.
