A wet spray material for a firing furnace, which is capable of shortening a time until the firing furnace becomes ready for operation after spraying onto a construction target surface of the firing furnace, and a construction method using the wet spray material. Specifically, a refractory raw material comprising 55% by mass to 90% by mass of particles having a particle size of less than 1 mm is kneaded with silica sol and water added thereto, and the resulting kneaded material is pressure-fed to a nozzle, and, after adding thereto a slurry or aqueous solution of at least one or more selected from the group consisting of calcium hydroxide, magnesium hydroxide, calcium chloride, potassium chloride, magnesium chloride, sodium chloride, calcium sulfate, potassium sulfate, sodium sulfate, calcium nitrate, magnesium nitrate, sodium nitrate, and potassium nitrate, in or just before the nozzle, sprayed onto a construction target surface.
A wet spray material for a firing furnace, obtained by adding silica sol, and a slurry or aqueous solution of at least one or more selected from the group consisting of calcium hydroxide, magnesium hydroxide, calcium chloride, potassium chloride, magnesium chloride, sodium chloride, calcium sulfate, potassium sulfate, sodium sulfate, calcium nitrate, magnesium nitrate, sodium nitrate, and potassium nitrate, to a refractory raw material comprising 55% by mass to 90% by mass of particles having a particle size of less than 1 mm, wherein:
A construction method using a wet spray material for a firing furnace, comprising:
