Special Shaped Corundum Mullite Insulating Refractory Bricks With Acid Resistant
Quick Detail:
♦ Compact microstructure
♦ Good erosion resistibility to molten glass
♦ Good thermal shock resistibility
♦ Barely rendering blister
Applications:
Corundum mullite Brick is mainly used for side walls of flame furnaces with embedded melter bottoms, for total security with average pulls and campaign lengths, and superstructures, front wall, back wall, top crown in glass melting furnace.
