Fused cast AZS block is the largest consumption species of fused refractory material at present. Glass erosion resistance is strong, with different composition of the glass can adapt. The product categories of fused cast AZS block are as follows:
1. According to zirconia content, fused cast AZS block is divided into three grades: 33 # AZS, 36 # AZS, 41 # AZS.
In general, with the improvement of zirconium dioxide content, baddeleyite mineral content increased, improved glass erosion resistance and high temperature softening property.
2. By casting method, AZS is divided into four types: ordinary casting (PT), tilted casting (QX), Quasi no shrinkage casting (ZWS), no shrinkage casting (WS).
3. According to production process method, products are divided into oxidation (Y) and reduction method (H) oxidizing atmosphere. Main impurity in fused cast AZS block is Fe3 +, Ti4 +, glass phase seepage temperature is high, greater than 1400
