Fused zirconia corundum brick commonly known as white iron brick or cast zirconium corundum brick. It is to ensure the normal operation of the glass furnace the most important refractory, the current domestic and foreign glass melting furnace to improve the melting rate, to extend the kiln age, reduce fuel consumption is mainly due to the use of this refractory material can be achieved.
With the increase of ZrO2 content, the performance of the fused zirconia corundum brick increases with the increase of the ZrO2 content. Generally, the zirconia corundum brick is divided into several grades, such as 33%, 36% and 41% Containing 30%, 40X, 50% of the level, not yet unified. The current use of more is 33% of zirconium products, the density of 3.65-3.7g / cm3, the maximum temperature about 1700 C.
