Refractory castables are unshaped refractory materials that can be mixed on-site with water and cast into virtually any form. They consist of carefully graded refractory aggregates, hydraulic or chemical binders, and performance-enhancing additives.
Their formability and durability make them suitable for both new installations and repairs in furnaces, kilns, incinerators, and similar thermal equipment. Castables are valued for their versatile application, thermal shock resistance, and ability to accommodate complex geometries, reducing the number of joints and potential failure points.
Refractory castables are advanced materials used to form monolithic linings in furnaces, kilns, incinerators, and other high-temperature industrial units. Due to their outstanding thermal performance, mechanical strength, and adaptability, castable refractories play a critical role in the construction and maintenance of high-temperature installations. Castables can be categorised into several types based on their composition and application method: conventional, low iron, low cement, and insulating. They may be installed via gunning, casting, or manual application, depending on project requirements. Refractory castables are formulated from a wide range of raw materials, including chamotte, andalusite, bauxite, mullite, corundum, tabular alumina, and silicon carbide. For insulation purposes, lightweight aggregates such as perlite and vermiculite are incorporated.
Compared to traditional refractory bricks, castable refractories offer several key benefits:
