In industrial settings, high temperatures, chemical corrosion, and mechanical wear pose major challenges. Choosing the right refractory material is key to stable operation, lower maintenance costs, and longer equipment life. SK36 bricks are a reliable high-alumina refractory option, renowned for their excellent performance and versatility, making them the top choice for businesses needing durable, cost-effective solutions.
As high-alumina refractory bricks, SK36 contains about 55% alumina (Al₂O₃), ensuring superior high-temperature resistance. With a refractoriness of up to 1770℃ and a refractoriness under load (0.2MPa) of at least 1450℃, they operate stably without deformation. Their bulk density of 2.25-2.3 g/cm³ and apparent porosity of 23-24% balance thermal insulation and structural strength, reducing heat loss while maintaining good load-bearing capacity.
A key advantage of SK36 bricks is their strong comprehensive performance. They have excellent thermal shock resistance, withstanding rapid temperature changes without spalling or cracking—critical for equipment with frequent heating and cooling cycles. They also resist acidic and alkaline slag erosion and have a cold crushing strength of 45MPa, ensuring durability during installation and long-term use.
Made from high-quality bauxite through strict mixing, molding, and high-temperature sintering, SK36 meets ISO 9001 standards for consistent quality. Available in standard size (230×114×65mm) and custom shapes, they fit most applications without extra mold costs.
SK36 bricks are widely used in metallurgy (blast furnaces, heat treatment furnaces), building materials (cement rotary kilns, ceramic kilns), chemicals (corrosive high-temperature vessels), and other industries like waste incineration and glass manufacturing. Their cost-effectiveness, long service life, and easy installation help businesses cut maintenance and operational costs, boosting efficiency.
Whether in metallurgy, building materials, or chemicals, SK36 offers a high-performance, cost-effective refractory solution. Backed by strict quality control, sufficient inventory, and prompt delivery, we provide customized solutions to meet your needs. Choose SK36 to protect your equipment, reduce risks, and achieve stable long-term production.
