Dense fireclay brick
MARSREF is a supplier of dense fireclay brick refractory materials. This product is made of coke gem, mullite, "three stones" and composite ultrafine powder as the main raw materials, combined with high-quality soft clay, and formed by high pressure and sintered at high temperature. It has the advantages of high crushing strength, high under load temperature and strong permeability resistance.
The products are mainly used in general industrial furnaces such as blast furnaces, lime kilns, cement kilns, glass kilns, steel ladle, molten iron tanks.
