The expansion curve of the AZS brick has an anomaly near 1000 °C, and the internal ZrO2 crystal undergoes a reversible crystal transformation with a large volume change. Therefore, the product containing ZrO2 should not be used at around 1000 °C, the temperature is often A region that fluctuates sharply. When baking the kiln, the temperature change at 900~1150 °C should not be too large, generally can not exceed 15 °C / h, requiring a steady temperature rise. Some AZS refractory parts should be protected from blowing cold air and protected by other bricks to prevent cracking.
2.AZS Bricks Shrinkage
When casting, there are often shrinkage holes in the casting mouth, the brick body has more pores and poor density. Therefore, when the glass wall of the glass melting part is made, the shrinkage holes are directed toward the direction of the kiln. When AZS brick is eroded to a very thin level, AZS refractory bricks will cause a leakage of glass liquid. When used in the upper flame space of the kiln, the service life is very long, there is no problem of running glass. Therefore, the casting port is used outwards to extend the service life.
3.AZS Bricks Eutectic
The AZS firebrick and the clay brick are in contact with the clay brick. The eutectic phenomenon occurs at a high temperature of 1300 °C. Therefore, when the refractory material is selected, the two refractory materials with severe eutectic phenomena should be avoided from contact with the masonry, such as silica brick casting. Below the zirconium corundum brick,AZS brick is most susceptible to erosion by the cast zirconia corundum brick.
AZS Bricks Packing & Delivery
Consider various and complex transportation conditions, fused cast azs products are packing following the highest standards with foam boards between every two AZS blocks, AZS refractory bricks corners protected with triangular hard card boards and multi-strengthened by steel bands and wrapping in plastic film on the outside.
For easy location of different materials,packing lists are places both inside and outside packages, and shipping marks are clearly painted on all cases.
