PERFORMANCE UNDER PRESSURE — SPINEL BRICK SOLUTIONS FOR IRON & STEEL APPLICATIONS

ENGINEERED FOR HEAT, LOAD & LONGEVITY

Iron and steel production demands materials that can take the heat — and everything else that comes with it. From blast furnaces to reheat furnaces, ladles to tundishes, refractory linings face extreme abrasion, thermal cycling, slag attack, and mechanical stress. In this environment, lining failure isn’t just costly; it can shut a plant down

DGC Refractories supplies a full range of shaped spinel brick solutions, engineered for uncompromising durability, thermal stability, and extended campaign life in the toughest metallurgical conditions.

ADVANCED SPINEL TECHNOLOGY FOR STEELMAKING

Our magnesia-based spinel bricks are developed to provide optimal resistance to:

·       High-temperature slag corrosion, especially in basic oxygen and electric arc furnaces

·       Mechanical wear in ladles, RH degassers, and converter linings

·       Thermal cycling and structural cracking, particularly in reheat furnaces and steel ladle walls

Key products include:

·       Magnesia-Alumina Spinel Bricks – exceptional corrosion resistance and thermal shock performance

·       Magnesia-Iron Spinel Bricks – engineered for high-load-bearing capacity and mechanical robustness

These materials combine high-purity raw materials with consistent manufacturing control, ensuring dimensional precision and dependable installation outcomes.

SUPPORT THAT REDUCES DOWNTIME

DGC Refractories brings more than just brick to the table. We work with our clients to:

·       Define application-specific material selection across each furnace zone

·       Ensure third-party QA/QC validation to meet client technical specifications

·       Coordinate site logistics and delivery planning for shutdowns and maintenance schedules

·       Provide technical input during installation and post-campaign performance reviews

Whether your challenge is slag penetration in a converter lining or hot face erosion in a preheater, we bring targeted material solutions backed by operational insight.

PROVEN EXPERIENCE IN SOUTH AFRICAN STEELMAKING

DGC has supported steel plants and iron producers across South Africa, with a deep understanding of the unique operational environments, technical requirements, and shutdown schedules of the region’s metallurgical industry.

Our spinel bricks have been successfully applied in:

·       Electric arc furnaces (EAF) and basic oxygen furnaces (BOF)

·       Steel ladles and tundishes

·       Hot blast stoves and preheaters

·       Reheat and forging furnaces

By combining precision-engineered materials with local technical expertise, DGC delivers fit-for-purpose refractory solutions that meet both performance and budgetary expectations.
