Clay-based refractory mortar is a type of refractory material primarily composed of natural clay. It exhibits excellent binding properties and high-temperature resistance, making it widely applicable in furnace and kiln joints across industries such as steel, glass, ceramics, and cement. · Superior Binding Capacity: Effectively bonds refractory bricks to maintain structural integrity of furnaces and kilns. · Exceptional Refractory Performance: High refractoriness under load (RUL) ensures stability in extreme heat environments. · Enhanced Workability: Offers excellent plasticity for easy installation and allows customization of shapes/sizes to meet specific project requirements.
Steel Industry: Joint sealing in blast furnaces and hot blast stoves.
Glass Industry: Gap filling in glass melting furnaces.
Ceramics Industry: Kiln joint construction in ceramic firing processes.
Cement Industry: Seam reinforcement in cement rotary kilns.
