Electro cast corundum blocks, produced from pure alumina (Al₂O₃) with high alumina content, offer exceptional mechanical and thermal strength, providing excellent resistance to wear and erosion in glass, steel and foundry furnaces. They maintain dimensional stability at high temperatures, ensuring long service life and improved energy efficiency in furnace operations.

The corundum blocks supplied by Termoref stand out with their low porosity, high thermal shock resistance and chemical stability. Electro cast corundum blocks are ideal solutions for glass melting lines, ladle areas and highly abrasive environments. With various density and size options, our company provides reliable and high-performance refractory solutions for industrial furnaces.
