Description of SK Fireclay Bricks

SK Fireclay Bricks 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 30% Al₂O₃ and no more than 2% Fe₂O₃. This chemical composition gives it excellent chemical stability and resistance to slag.

我们供应 SK 系列耐火砖。根据出口标准，SK30/32/34 为粘土砖，SK36~40 为高铝砖。具体规格可根据客户要求定制。欢迎随时咨询！
