Glass factory refractory bricks

Size: customized

Material: high aluminum

Features：

The main chemical components of special refractory materials are A12O3 and SiO2. The grades of low-porosity clay bricks for glass kilns are divided into three types according to their porosity: DN11/ DN14/ DN17, among which D/N/11/14/ 17 points: According to the main mineral composition of glass kiln low porosity viscosity bricks belong to the aluminum silicate system, which respectively represent low, viscosity, and porosity values. Ground porosity clay bricks are the most commonly used type of refractory in glass kilns. Bricks, their output value accounts for about 70% of the total output value of shaped refractory bricks.

In different parts of the furnace, due to different erosion conditions, different grades of clay bricks can be used. The lower grate and checker bricks in the lower part of the regenerator are less eroded by batch dust and volatile matter, have a lower temperature, and have a heavy load, which mainly requires high mechanical strength. Therefore, the combination in the brick can contain an appropriate amount of Fe2O3, Na2O and K2O. However, clay bricks used in high-temperature locations mainly require high load-bearing and high softening temperatures. The combination contains less impurities such as Fe2O3, Na2O and K2O, and is used in glass kilns. Low porosity clay bricks small bricks and large refractory bricks
