Product Detail

MARSREF is a supplier of low creep fireclay refractory brick. The difference between low creep fireclay brick and ordinary clay brick lies in the different production process. Low creep fireclay brick is made of super coke gem, andalusite and mullite as main raw materials, supplemented with special additives, and is formed under high pressure and fired at high temperature. It contains 40% to 48% alumina and has a refractoriness of 1580 to 1770℃.  


Low creep fireclay bricks are generally used in high temperature kilns such as blast furnace and hot air blast stoves and aluminum industrial carbon roasting furnaces.
