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.
Forniamo mattoni refrattari della serie SK. Secondo gli standard di esportazione, SK30/32/34 sono mattoni di argilla e SK36~40 sono mattoni ad alto contenuto di allumina. Le specifiche possono essere personalizzate. Benvenuti a chiedere informazioni in qualsiasi momento!
