The role of Fused Cast AZS Bricks in Glass Furnaces

For a glass kiln, Fused Cast AZS Bricks effect in galss furnace is very important, in order to achieve the design life or to avoid contamination of the glass solution, a thorough understanding of the appearance quality and intrinsic quality of the fused cast bricks is required. we need to understand the performance of the fused cast azs bricks and the weak points of the fused cast bricks.



First, the appearance quality of Fused Cast AZS Bricks in Glass Furnaces, the pool wall part of the corner brick, kiln chopped brick, bubbling bricks, liquid flow brick is generally fused cast azs 41#. With the neighboring brick assembly gap to be strict requirements, the gap assembly to speed up the glass solution on the brick erosion, assembly The gap requirement is not more than 0.5mm. It is advisable that there is no shrinkage hole at the bottom of the brick. More than twelve per cubic meter of surface air holes above the ¢2mm are not allowed. The color of the brick body is yellowish and white, bubbling, and liquid flow bricks are not allowed. The presence of cracks does not allow the presence of flaws within 300 mm of the top of the pool wall section.

Second, the intrinsic quality of Fused Cast AZS Bricks in Glass Furnaces.
1. From the brick color to determine the impurities in the fused cast brick, or to determine whether the carbon content is large, the color of the large carbon brick will be green, this brick is strictly prohibited.
2. While a massive greening on the surface of the brick body, there must be iron blocks inside. The iron blocks come from the flat material in the production process or the iron and solder part of the exhaust gas falls off, and other factors. This imagined brick is also prohibited.
3. The glass phase contrast must be strictly controlled. When the glass phase exceeds the standard, the large amount of glass phase precipitated at high temperatures can reduce the service life of the furnace and contaminate the glass melt.
