SK34 Firebrick is a high quality Clay refractory brick. It typically has a yellowish color and a standard cuboid shape, often with dimensions like 230×114×65mm. Classified as fire clay brick, it contains at least 38% Al₂O₃ and no more than 2% Fe₂O₃. This chemical composition gives it excellent chemical stability and resistance to slag.
We supply SK series refractory bricks. According to export standards, SK30/32/34 are clay bricks, and SK36~40 are high-alumina bricks. Specific specifications can be customized. Welcome to inquire at any time!
