Product Description Product FeaturesCorundum Mullite Pusher Trays face numerous interfering forces when pushing forward: compression, thrust, high-temperature pressure, friction, and thermal shock resistance, among others. Therefore, high-alumina pusher trays need to possess excellent thermal shock resistance and high-temperature compressive strength. Corundum Mullite Pusher Trays are high-performance refractory ceramic components designed for use in continuous high-temperature applications such as sintering, heat treatment, and firing processes in tunnel kilns, roller kilns, and pusher-type furnaces. These trays are manufactured from a carefully engineered blend of corundum (Al2O3) and mullite (3Al2O3·2SiO2), materials well known for their excellent thermal stability, high mechanical strength, and outstanding resistance to chemical attack and thermal shock.Thanks to their robust composition and optimized microstructure, Corundum Mullite Pusher Trays can withstand continuous operating temperatures up to 1600°C, offering exceptional dimensional stability even after repeated heating and cooling cycles. This makes them ideal for demanding industrial environments such as powder metallurgy, advanced ceramics sintering, magnetic materials processing, and other high-precision thermal applications.These trays are specifically designed to support and transport products smoothly through kiln systems, maintaining flatness and mechanical integrity under both thermal and mechanical stress. Their low creep deformation, high resistance to warping, and long service life significantly reduce maintenance costs and increase production efficiency. Additionally, the trays exhibit excellent resistance to erosion and corrosion from aggressive kiln atmospheres and process residues.Standard sizes are available, but custom shapes and specifications can also be manufactured according to customer requirements, including trays with perforations, grooves, or raised borders to optimize load distribution and airflow during thermal processing.Corundum Mullite Pusher Trays are widely used in industries such as ceramics, electronics, metallurgy, and new energy materials. Their superior performance, high reliability, and cost-effectiveness make them an essential component in modern high-temperature industrial systems.Application ScopeLong-term usage temperature of 1650oC, outstanding thermal shock resistance, high compressive strength, good elastic modulus, and an exceptionally long service life.Technical ParametersAl2O3(%)87.78SiO2 (%)11.9Fe2O3(%)0.08NaO(%)<=0.3Temperature Limit (?C)1650Thermal Expansion Rate x 10-6at 1000 ?C2.70Open Porosity (%)20.0Bulk Density (g/cm3)2.99
