Gunning material is applied by spraying equipment, with Al₂O₃ ≥60%, service up to 1500℃ and rebound ≤10%. No formwork is needed—fast installation, on-line hot repair and full monolithic linings are possible. It is Henan Songrui's efficient grade for boiler furnaces and walls.
Gunning suits rapid construction and on-line repair; castables give more uniform performance for new large linings. Combine "cast for new, gun for maintenance" for economy.
Cure and dry after spraying before rapid heat-up; control thickness and interlayer bonding to prevent delamination. Spraying guidance available.
