1. Characteristics of sintered AZS bricks for glass kilns
①. Good corrosion resistance.
②. Good wear resistance.
③. Good thermal shock performance at high temperature.
2. Application of sintered AZS bricks for glass kilns
The sintered AZS brick for glass kiln is generally used as the working layer of the glass kiln, which is in contact with the molten glass, protecting the kiln and resisting the erosion of the molten glass. Therefore, sintered AZS bricks are mainly used for the parapet wall of the melting part of the glass tank kiln and the sealing layer at the bottom of the arch foot tank.
