HuanGang SK36 45% High Alumina Refractory Bricks | Neutral Acid Resistant Fire Bricks for Steel Casting

Our HuanGang SK36 45% high alumina refractory bricks are neutral, acid-resistant fire bricks engineered for high-temperature steel casting and foundry applications. Manufactured with high-purity alumina block material, these refractory bricks offer reliable thermal stability, excellent acid resistance and consistent performance at operating temperatures between 1580°C and 1770°C, making them the ideal choice for furnace lining in the steel casting industry.

Key Features of Our 45% High Alumina Refractory Bricks

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

• Neutral Acid Resistance: Formulated with a balanced chemical composition (45% Al2O3, 50% SiO2), these bricks exhibit excellent resistance to acidic environments and chemical attack, extending service life in corrosive steel casting conditions.

• Optimized Chemical Composition: Featuring 45% Al2O3, 50% SiO2, and controlled trace elements (1% CaO, 0.2% MgO), with zero CrO and SiC content, these bricks deliver consistent mechanical strength, thermal shock resistance and dimensional stability.

• 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 or foundry 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 foundry applications.
