Japanese Patent JP7029299

B2

To improve a corrosion resistance while ensuring the heat insulation in castable refractory.SOLUTION: A castable refractory of this invention contains: a sillimanite group material having a particle size of less than 1 mm; a boron compound; and at least one of a lightweight aggregate, an air entraining agent, and organic fibers. And each content of the castable refractory as a percentage of 100% by mass of raw materials excluding refractory raw materials with a particle size of 8 mm or more is as follows: the content of the sillimanite group raw material having a particle size of less than 1 mm is 5 mass% or more and 70 mass% or less; the boron compound content is 0.08 mass% or more and 2 mass% or less as the boron content; when the lightweight aggregate is contained, its content is 10 mass% or more and 50 mass% or less; when the air entraining agent is contained, its content is 0.02 mass% or more and 0.5 mass% or less; when the organic fiber is contained, its content is 0.5 mass% or more and 3 mass% or less.SELECTED DRAWING: None
