Fused cast AZS 41 block introduce:
Using WS cast method, fused cast AZS 41 refractory block is high quality refractory with zircon sand and industrial alumina powder as its raw material, and the percentage of ZrO2 is 41%. Among zirconia-alumina brick (AZS) series, fused cast AZS 41 refractory block has the best corrosion resistance from glass liquid, and the glass pollution nearly close to null. So fused cast AZS 41 block usually be used in key part of glass furnace that demand high corrosion resistance like electric-melting tank, dog hole, doghouse corner, tank bottom bubbling brick and so on.
