Ultra-high temperature high-purity castables based on brown/white fused corundum.
Corundum castables use brown/white fused alumina aggregate with low CaO and service temperatures above 1700℃, delivering high hot strength and slag resistance. Widely used for ladle slag lines, BF main troughs, gasifiers and WTE secondary combustion chambers as high-end low-/ultra-low-cement grades.
