How to extend the service life of fused zirconium corundum bricks (hashtag#AZS bricks) in glass kilns by controlling the erosion mechanism?

Protection from physical effects:
Reduce the impact of rapid cooling and heating on the brick body, and reduce temperature fluctuations by optimizing the operation process of the kiln. Ensure the integrity of the brick structure to avoid cracks and peeling.

Protection from chemical effects:
Strictly control the Na2O content in the raw materials, because Na2O will intensify the precipitation and diffusion of the glass phase, thereby accelerating erosion.
When designing the brick body, ensure that the ratio of the riser to the brick material reaches 1.5:1 to reduce pore residue and enhance erosion resistance.
Check the brick joints during assembly to ensure that they are below 0.3mm, and control the expansion difference during the kiln baking process to maintain the tightness of the brick joints.
