Manufacturing LCC, ULCC, and other high-alumina castables.
-
Base material for Alumina-Silicon Carbide-Carbon (ASC) and Alumina-Carbon bricks for torpedo ladles.
-
Used as a base material in various continuous casting refractory areas of the steel industry.
-
Suitable for trough castables and precast shapes of blast furnace runners.
It is particularly effective in high-performance areas of the high-alumina sector due to its purity and durability.
Product Features:
1.
High Alumina Content & Low Impurities – Provides superior thermal and chemical resistance, ensuring longer service life in demanding refractory applications.
2.
Versatile Material – Suitable for castables, bricks, and precast shapes, reducing the need for multiple raw materials and improving operational efficiency.
3.
Optimized for High-Performance Areas – Handles aggressive continuous casting and high-stress zones, enhancing reliability and overall refractory performance.
Synthetic alumina is a high-purity brown corundum produced by the controlled fusion of specially graded calcined alumina with other raw materials in an electric arc furnace. Precise process control ensures consistent quality, and its excellent high-temperature properties make it ideal for high-alumina refractory applications.
