The Advantages Of Fused Cast AZS Block 41# In Glass Industry

 

AZS 41# block is produced with zircon sand by melting it in the mold with high temperature, then cooling and solidification. Desilication zircon sand is added to increase the ZrO2 content and decrease the glass phase, which greatly improve the corrosion resistance and other physical and chemical properties.

 

AZS 41 block has high corrosion resistance due to its high quality material and special casting method which leads to its good dense structure. Compared to AZS 36# and 33# , it contains more zirconia crystals which makes its structure denser, and this leads to its extremely stronger corrosion resistance and lower pollution to glass liquid. 

 

What’s more, this material has good castability which enables the production to make a great variety of large size straight or approximate straight bricks and special formats and shapes which are available for special machine process. 

 

In addition, different casting methods can produce different types of AZS 41# to fulfill different demands for different parts of glass furnace. AZS 41# produced with the void-free-cating(WS) method which has almost no shrinkage voids left in brick as it is cut off.

 

AZS 41 block is widely applied in demanding areas of glass furnaces such as sidewall, doghouse corner, throat, dam wall, bubbling block, electric block corner and all parts of electric furnace.

 

However, as the ZrO2 content increases, the manufacturing cost and price of the AZS blocks increase too. So glass makers need to make a purchase decision based on both the cost and performance. 

AZS 41# block from Sunrise Refractory is made with Australia imported superior zircon sand. This professional casting method also ensures its long service life.
