Title:
HIGH-ALUMINA MELT-CASTED REFRACTORY AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/174719
Kind Code:
A1
Abstract:
The present invention provides: a high-alumina casted refractory which can be manufactured easily and has a small porosity and high corrosion resistance; and a method for manufacturing the high-alumina casted refractory. The high-alumina casted refractory according to the present invention has the following chemical composition: 95.0 to 99.5% by mass of Al2O3, 0.20 to 1.50% by mass of SiO2, 0.05 to 1.50% by mass of B2O3, 0.05 to 1.20% by mass of MgO, and a remainder. The method for manufacturing a high-alumina casted refractory according to the present invention comprises: mixing an Al2O3 raw material, an SiO2 raw material, a B2O3 raw material and an MgO raw material together to produce a mixture; and melting the mixture.
