High Strength high temperature Refractory casette for kiln firing
1. Details
Our refractory casette is widely used to sinter powder, like rare earth powder, phosphor, pigment, sponge iron and so on. When these powder sintered in kiln, powder itself has water ,it has bad effect to using life. So it must has high thermal shock resistance when sintering.
Casette, is made of refractory mud material of a variety of round bowl, made by high temperature roasting. The casette is one of the important kilns for the installation of porcelain. All kinds of porcelain billet, must first be loaded into the casette, and then into the furnace roasting.
high temperature casette used for ceramics has high refractoriness, good thermal shock resistance, high load softening temperature, small expansion coefficient, long life and other fine features, widely used in ceramics industry (tunnel kiln brick, roller Kiln, Pusher kiln , a variety of casetter) and other kilns instead of clay and high aluminum brick, with good effect.
