HuanGang SK38 45% Al2O3 Refractory Bricks | Medium Duty Wear Resistant Fire Bricks for Steel Furnaces

Our HuanGang SK38 45% alumina refractory bricks are medium-duty, wear-resistant fire bricks engineered for high-temperature industrial applications, particularly steel making furnaces. Manufactured with high-purity alumina block material, these refractory bricks offer reliable performance, excellent wear resistance and consistent thermal stability at operating temperatures between 1580°C and 1770°C, making them the ideal choice for furnace lining in steel production and other thermal processing operations.

Key Features of Our 45% Alumina Refractory Bricks

• Controlled Refractoriness & Thermal Stability: With a refractoriness rating of 1580°C to 1770°C, these medium-duty refractory bricks maintain structural integrity and thermal performance in continuous high-temperature operations, ensuring reliable service in steel making furnaces.

• Optimized Chemical Composition: Formulated with 45% Al2O3, 50% SiO2, and controlled trace elements (1% CaO, 0.2% MgO), these bricks balance strength, thermal shock resistance and chemical stability, with zero CrO and SiC content for consistent quality.

• Excellent Wear & Abrasion Resistance: The dense, homogeneous structure of these alumina refractory bricks provides superior resistance to mechanical abrasion, erosion and thermal cycling, extending service life in high-wear steel furnace environments.

• Standardized Dimensions & Custom Mold Services: Available in standard 25x15x8cm brick size (gross weight 4kg), with custom mold opening services to create specialized shapes for your specific furnace lining design.

• Factory Direct Quality & Reliability: Manufactured in Henan, China under strict quality control standards, these YuanCheng refractory bricks deliver consistent performance, dimensional accuracy and long-term durability for industrial furnace applications.
