Refractory

Refractories play a crucial role across various high-temperature industries, and CUMI offers specialized solutions tailored to each sector’s needs.

In the steel industry, refractories are used for lining blast furnaces,, and converters, and CUMI provides durable alumina and zirconia-based refractories that resist thermal shock and chemical erosion, enhancing operational life.

For the cement industry, where rotary kilns, preheaters, and coolers demand high abrasion and alkali resistance, CUMI delivers monolithic refractories and castables engineered for superior performance. In glass manufacturing, where thermal insulation and purity are critical, CUMI’s fused silica and alumina-based refractories are ideal for tank mm blocks, furnace crowns, and regenerators. In non-ferrous metal industries, where aluminum andcopper melting require clean operations and long-lasting crucibles, CUMI supplies corrosion-resistant fused. materials like brown fused alumina and silicon carbide. For power plants and petrochemical industries, including boilers, incinerators, and reformers, CUMI offers high-alumina castables, insulating bricks, and ramming masses that perform reliably under extreme thermal and chemical conditions.

With in-house production of fused minerals such as brown fused alumina, white fused alumina, and silicon carbide, CUMI ensures consistent quality, global delivery, and technical support for customized refractory solutions across critical industrial applications.
