SK32 brick is a premium fire clay refractory brick designed for medium-temperature industrial applications. Famous for outstanding thermal stability, robust mechanical strength and high cost performance, this standard refractory brick is widely adopted for kiln and furnace lining solutions worldwide. Optimized for harsh high-temperature working environments, SK32 fire brick perfectly balances durability, flexibility and economy, making it a mainstream choice for various industrial thermal equipment.
Technical Performance
SK32 refractory brick features stable physical and chemical properties with an alumina content of over 35%, a bulk density of 1.95-2.1g/cm³ and a cold crushing strength of 45MPa. It offers a load softening temperature of 1300°C and a maximum refractoriness of 1430°C, fully satisfying long-term continuous operation of medium-temperature industrial furnaces. With low porosity, low thermal expansion, excellent thermal shock resistance and strong slag resistance, the brick effectively resists cracking and abrasion from frequent temperature fluctuations, significantly prolonging furnace lining service life.
Dimensions & Economy
SK32 brick adopts the universal standard size of 230*114*65mm, compatible with most industrial kiln lining structures. Custom specifications are available to meet personalized project requirements. Manufactured with advanced eco-friendly techniques, our SK32 bricks have low impurities and stable performance under prolonged high-temperature conditions. Compared with high-grade refractory products, SK32 bricks deliver reliable protective performance at a more competitive price, ideal for large-scale industrial procurement and construction projects.
Versatile Industrial Applications
Versatile and practical, SK32 refractory bricks serve diverse industrial fields. They are commonly used for lining blast furnaces, hot blast stoves and cupola furnaces in the metallurgy industry. In cement and ceramic manufacturing, they fit rotary kilns, preheating zones and cyclone linings perfectly. They also work steadily in non-ferrous metal smelting furnaces and glass factory regenerator walls, covering most medium-temperature kiln working scenarios.
