JXAG-30
The high-purity chrome-corundum brick is made mainly from high-purity corundum and fused chromium oxide with a certain amount of additives, by high-pressure forming and high-temperature firing. It has low porosity, good density, high strength and good slag resistance — a product of excellent performance, particularly suitable for Ausmelt smelting furnaces, zinc-powder electric furnaces and other high-temperature furnaces.
