Product Information
High alumina runner bricks are refractory bricks used in furnace bottoms to form molten metal flow channels. Made of high-purity bauxite aggregates with an alumina content of 70% to 90%, these runner bricks have high refractoriness, chemical inertness, and thermal shock stability.
They withstand extreme temperatures, corrosion, and mechanical damage.
Our high alumina runner bricks improve the flow of molten materials in blast furnaces, steel ladles, tundishes, and other high-temperature applications. They help enhance productivity, reduce defects, and prolong equipment service life.
