Our refractory materials are critical to every stage of steelmaking. In Blast Furnaces, they line the hearth and bosh, resisting molten iron and slag erosion. In Basic Oxygen Furnaces (BOF) and Electric Arc Furnaces (EAF), our magnesia-carbon and alumina-carbon bricks form the first line of defense against temperatures exceeding 1,700°C, ensuring the integrity of the furnace structure during the intense melting and refining cycles. Beyond the primary vessels, our refractory castables and ramming mixes are used to repair and maintain ladles, tundishes, and converters, minimizing downtime and maximizing productivity. By optimizing heat retention and reducing material wear, our solutions directly contribute to the efficiency and sustainability of steel production.

Our refractory materials are designed to maintain the stability of glass furnaces, which operate continuously at temperatures up to 1,600°C. The melting tank is lined with our fused cast AZS (Alumina-Zirconia-Silica) bricks and fused cast refractories, which offer exceptional resistance to corrosion by molten glass and aggressive alkali vapors. In the regenerator chambers, our silica bricks and high-alumina refractory castable efficiently store and transfer heat, significantly reducing energy consumption. For the forehearths and tin baths in float glass production, our specialized refractories ensure uniform temperature distribution, critical for achieving the highest quality flat glass. The durability of our materials translates to longer furnace campaigns, fewer maintenance interruptions, and consistent glass quality.

Cement production is one of the most energy-intensive industrial processes, relying on refractory materials to endure extreme temperatures, mechanical abrasion, and chemical attack. Our comprehensive range of refractories is tailored to each zone of the cement kiln system. In the preheater and calciner, our alkali-resistant bricks and low-cement castable protect against alkali vapor corrosion and high-velocity gas erosion. The rotary kiln—the heart of the process—uses our magnesia-spinel bricks in the burning zone, where temperatures reach 1,450°C and the lining is subjected to molten clinker attack. Our lightweight insulation materials and castables are applied to the kiln shell and cooler, improving thermal efficiency and reducing heat loss. By extending the service life of critical components and enhancing energy efficiency, our refractories play a pivotal role in the sustainability of cement manufacturing.

Our refractories line the walls, floors, and crowns of tunnel kilns, roller kilns, and shuttle kilns, providing the thermal stability required for consistent firing cycles. In roller kilns, our advanced alumina-mullite and silicon carbide rollers ensure uniform heat transfer and resist deformation at temperatures up to 1,300°C, guaranteeing the flatness and quality of ceramic tiles and tableware. Our refractory fibers and boards are used for insulation, reducing energy consumption and optimizing process control. Additionally, our refractory castables and mortars are essential for the construction and maintenance of kiln cars and saggers. By enabling precise temperature control and minimizing product defects, our materials are integral to the production of high-quality ceramic goods.

Aluminum production is a complex, energy-intensive process that places unique demands on refractory materials.
In Aluminum Electrolytic Cells, the primary method for smelting aluminum, our carbon cathode blocks and sidewall refractories must resist the highly corrosive molten electrolyte (bath) and molten aluminum at temperatures around 960°C. Our specialty isostatically pressed (CIP) graphite and alumina-based refractories ensure the structural integrity of the cell, maximizing its operational life and efficiency. Beyond primary production, our refractory materials are used in melting and holding furnaces for secondary aluminum production, where they provide excellent thermal insulation and resistance to dross formation.
