DRY SPRAYING MATERIAL FOR FIRING FURNACE
The present invention provides a dry spraying material for a firing furnace, which is free from a need for a drying process after spraying, and capable of withstanding physical shock from furnace contents. The dry spraying material according to the present invention is designed for a firing furnace having a furnace wall temperature of 1400°C or less, wherein a SiO2 component derived from raw materials having a particle size of less than 75 µm and an Al2O3 component derived from raw materials having a particle size of less than 75 µm are contained in the dry spraying material, respectively, in the dry spraying material in an amount of 1% by mass to 10% by mass and in an amount of 5% by mass to 40% by mass. Further, a basic compound fine powder of one or more types selected from the group consisting of magnesium oxide, magnesium carbonate, magnesium sulfate, magnesium nitrate, calcium oxide, calcium carbonate, calcium sulfate, and calcium nitrate each having a particle size of less than 75 µm is contained in a raw material mixture in a total amount of 0.1% by mass to 5% by mass. One or more types selected from alkali silicate and alkali phosphate are used as a binder, and the amount of usage of cement is limited to 5% by mass or less.
