Fused Mullite Bricks
Fused Cast Mullite Bricks Properties
Excellent thermal shock resistance can resist drastic temperature change.
Excellent abrasion resistance is suitable for high-temperature wearing parts.
Excellent permeation and chemical corrosion resistance.
Low thermal expansion rate, masonry has good structural stability.
High hot mechanical strength, can support a large load.

Fused Cast Mullite Bricks Application
Fused cast mullite bricks are mainly used at high-temperature parts of smelting furnaces, where suffer severe abrasion and chemical corrosion, such as sliding rail bricks of metallurgical Pusher-type heating furnace, walking-type heating furnace tapping platform (tapping spout) and garbage incinerator lining, etc.
