Our fused cast AZS #41 block has the most corundum-baddeleyite eutectic crystals among the electro-fused Al2O3-ZrO2-SiO2 series products. Its corrosion resistance is the best and therefore its normally recommended to be used in quick wear positions to prolong the furnace life. It is the most widely used material both in glass contact and superstructure of glass melting furnaces. Mainly applicable for sidewalls, doghouses, throat, bottom budding, dam blocks, electric block corners, and also linings of furnace in industries. Our product has passed ISO international certification, it is made from high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and so on. This product is available in a large size straight and special shapes which are available for special machining processes. We basically have three casting methods: PT, ZWS and WS, different required castings are manufactured accordingly.
