1. Overview of Fire Clay Bricks
Stable and standardized refractory materials are essential for industrial furnace operation and cost control. Fire clay bricks are premium medium-temperature refractory products sintered with high-purity refractory clay. Different from common building bricks, they feature stable physical and chemical properties, serving as a reliable and cost-effective lining solution for global industrial thermal equipment.
2. Standard Grades & Core Performance
We offer a complete series of fire clay bricks covering four mainstream industrial grades: SK30, SK32, SK33 and SK34, covering full-grade specifications for diverse medium-temperature working conditions. Our SK-series fire clay bricks feature graded alumina content ranging from 30% to 38%, with service temperatures spanning from 1580°C to 1720°C, achieving progressive performance from standard to high-grade. All grades adopt low-iron purified refractory clay, delivering stable bulk density, low porosity, excellent thermal shock resistance and strong slag corrosion resistance. They effectively prevent high-temperature cracking and deformation, ensuring long service life and outstanding cost-performance, which makes them a more economical choice compared with traditional high-alumina refractory bricks.
3. Specifications & Industrial Applications
Our fire clay bricks cover mainstream international standard sizes, including the classic 230×114×65mm, as well as 230×114×55mm and 230×114×75mm. Custom arched, wedge and special-shaped bricks are also available for non-standard furnace structures. Widely applicable to cement kilns, glass furnaces, industrial boilers, power plant thermal equipment, chemical gasification furnaces and metallurgical furnaces, they are ideal for new lining construction and equipment maintenance, helping enterprises reduce downtime and material replacement costs.
4. Custom Service & Inquiry
We strictly control core indicators including alumina content, impurity content, density and refractoriness for all SK series fire clay bricks to ensure stable batch quality. We provide free technical consultation, grade selection guidance and detailed product datasheets. If you are looking for qualified, cost-effective fire clay bricks for your industrial projects, send us an inquiry to get customized quotes and exclusive bulk discount offers.
