Document Type and Number:
Japanese Patent JP2021169393
Kind Code:
A
Abstract:
To provide a refractory raw material for spraying, for producing a monolithic refractory for wet spraying having improved durability, more concretely, heat-resistant spalling property while maintaining good workability.SOLUTION: A refractory raw material for spraying contains a refractory raw material as a main component, silica fume and calcined alumina as sub-components, and substantially contains no alumina cement. In the refractory raw material for spraying, the total content of silica fume and calcined alumina is 0.8-22 mass% based on 100 mass% of the refractory raw material for spraying, and the mass ratio of calcined alumina to silica fume is 0.4-2.5.SELECTED DRAWING: None
