company news about AZS and high zirconia brick

The fused AZS brick is mainly to improve the corrosion resistance and wear resistance of the production process, in addition to the oxidation of molten, make the product of carbon content to 0.005, improve the temperature of glass phase precipitation to 1450 degrees outside. Also on the casting and annealing process was improved, now produce high zirconia brick shrinkage volume is very small or even non fused AZS.ZrO2 content of shrinkage of more than 90, the thermal shock performance is very good, such as ZrO295, brick high zirconia SiO21.4. stabilizer 3.7, 4.7g/cm3 volume density, gas hole rate 18.4, thermal shock resistance from room temperature to 1400 C (15 minute intervals) up to 15 ~ 20 times. Japan produced a kind of fused cast zirconia brick, the zirconia content 90, called the ZFC brick, its corrosion resistance is better than the ZrO2 content of AZS brick 40, at the temperature of 1500~1600 DEG C, after 16 hours without glass phase precipitation, little pollution of glass, after 800 ~ 1250 DEG C thermal shock resistance test 40 times without crack.
