Corundum Mullite Pusher Trays

Product Features

Corundum 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.

Application Scope

Long-term usage temperature of 1650℃, outstanding thermal shock resistance, high compressive strength, good elastic modulus, and an exceptionally long service life.
