Novel ASC Refractory Design and Installation for Improved Energy Efficiency and Corrosion Resistance in Industrial Applications

Al 2 O 3 -SiC-C (ASC) lining bricks for pouring ladle used in pre-treating molten (desulfurization) iron and molten iron ladles, which offer advantages such as high oxidation resistance, strong resistance to slag corrosion, good thermal shock resistance, and excellent resistance to mechanical wear and abrasion, have been investigated. It is expected that the combination of these new techniques will improve the energy and economic efficiency of the steel industry while also contributing to the decarbonization of both the refractory and steel industries. Additionally, the developed technology is expected to be applicable to other energy-intensive industries, such as cement, glass, pulp and paper, and non-ferrous metal processing. Investigating used samples is crucial for reducing wear on both ALKO60A and ALKO66ASC linings. The microstructures of laboratory prepared samples were analyzed using OLM, XRD, and SEM/EDS techniques. It is expected the formation of phases with low melting points, along with spinel solid solutions in the matrix and calcium di-aluminate near the alumina aggregates.
