Composite brown corundum refractory bricks are made from high-quality raw materials such as brown corundum, semi-white corundum, dense corundum, and silicon carbide, refined through high-temperature, high-pressure molding and fine grinding processes. These bricks exhibit excellent thermal conductivity above 1000°C. Their uniform structure and optimal porosity ensure stable and consistent thermal conductivity. While slightly lower than that of molten cast bricks, they offer superior temperature adaptability. Their exceptional resistance to slag and alkali corrosion, combined with their high flexural strength and refractoriness under load, make them ideal for critical areas such as burners, tapholes, and slag ports in blast furnace linings. As one of our core products, composite brown corundum refractory bricks are designed to meet the stringent demands of the metallurgical industry, enabling international customers to achieve efficient and sustainable production operations.
