Refractory spraying equipment applies wet-mix castable or gunning material onto furnace, kiln, ladle, or heater surfaces to create or repair a heat-resistant lining, offering faster application than casting and generally lower rebound than dry gunning. It is used across UAE cement, steel, glass, and petrochemical plants for both scheduled shutdown relining and emergency hot repairs. Sparkline Group supplies spraying equipment configured for these different industry applications and mix types. Identifying your surface geometry and mix design early helps determine the right equipment configuration.
