SK38 High Alumina Bricks are premium-grade refractory products designed for demanding high-temperature industrial environments. Manufactured from selected high-quality bauxite and advanced additives, these bricks contain a minimum of 55% Al₂O₃, delivering excellent refractoriness, high mechanical strength, and superior resistance to thermal shock and chemical erosion.
SK38 high alumina bricks are widely used in steel, cement, glass, ceramics, and non-ferrous metal industries where reliable furnace lining performance is essential. Their excellent dimensional stability and durability under continuous high-temperature operation make them an ideal choice for modern industrial furnace systems.
