Ultra-low Cement Castable Refractory is a high-performance refractory material designed for use in extreme temperature environments. Made from high alumina bauxite and electric furnace high-temperature smelting corundum, it delivers exceptional erosion resistance, thermal shock resistance, and high compressive strength, making it ideal for various industrial applications.
Ultra-low cement castables are highly resistant to molten iron and slag erosion, offering extended service life in coke ovens, combustion chambers, and furnaces. They also have strong antioxidant capacity, minimal volume change upon reburning, and excellent impact resistance, ensuring durability and reliable performance under challenging conditions.
