Production process
Professional production of corundum mullite bricks
Oxidation melting casting AZS36
In addition to having the same cocrystallization as AZS-33# zirconium corundum brick, AZS-36# zirconium corundum brick is suitable for areas with faster glass flow rate and higher temperature, such as melting pool wall brick, paving brick, filler brick, etc., due to the increase of more chain-like zirconia crystals and the decrease of glass phase content, so the erosion resistance of AZS-36# zirconium corundum brick is further enhanced and the contamination to glass liquid is further reduced.
