Title:
MONOLITHIC REFRACTORY
Document Type and Number:
WIPO Patent Application WO/2019/049992
Kind Code:
A1
Abstract:
The purpose of the present invention is to ensure stable thermal insulation properties in a monolithic refractory comprising a silicon carbide raw material. Relative to 100 mass% of a refractory raw material, this monolithic refractory comprises: 20 to 50 mass% of a silicon carbide raw material having a particle size of 1 mm or greater; 2 to 15 mass% of fine alumina powder having a particle size of 1 to 10 μm; and 1 to 8 mass% of superfine silica powder having a particle size of less than 1 μm. Relative to 100 mass% of the refractory raw material, the content of alumina cement is 15 mass% or less (including 0) and the content of the silicon carbide raw material having a particle size of less than 1 mm is 5 mass% or less (including 0).
