CUMI specializes in providing advanced refractory solutions tailored for essential applications in primary aluminium production, encompassing reduction cells, melting and holding furnaces, and launders. Additionally, we extend our expertise to the smelting of copper and its alloys, specifically in cathode shaft furnaces.
In the electrolytic reduction process of alumina to aluminium, CUMI offers NBSiC blocks and shapes. These can either substitute or be used in tandem with graphite blocks, prebaked carbon blocks, and rammed carbon.
Melting furnaces, dedicated to melting ingot/recycled Aluminum and holding furnaces manage molten metal sourced from either the primary reduction potlines or the aforementioned melting furnaces. CUMI provides fused silica based products for molten metal transfer.
CUMI presents advanced NBSiC refractory materials, known for their superior oxidation resistance, tailor-made for the shaft furnace linings in Continuous Casting Rod (CCR) applications. Alongside this, we provide high-alumina castables adept for smelter environments, and Ramming mass designed for effective backup lining. Additionally, our range encompasses specialized consumables for the CCR process.
CUMI’s Oxide bonded Silicon carbide refractory materials are optimized for ISP furnaces, condensers. NBSiC for Zinc oxide furnace and. Additionally, we’ve engineered specialized castables uniquely designed for ladle applications,
