Fused cast AZS block is made of high pure raw materials in a special electric arc furnace by the casting process of long arc melting and oxidation treatment. There is almost no carbon contamination from the electrodes.
Due to the casting process and high pure materials, fused cast AZS block has super strong corrosion resistance to the glass liquid and low potential of pollution.
Fused cast AZS 33# block has great advantage in preventing the pollution from glass liquid. It can generate stones in glass and has low potential of glass precipitation and bubbling. It is suitable to the upper structure of the melting zone, the sidewall of the work tank, the paving blocks and the forehearth.
Fused cast AZS 36# block is the standard fused cast AZS block made by the oxidizing method. It has special high corrosion resistance to the glass liquid and has low potential of pollution. It is suitable for the areas that are in direct contact with the glass liquid, such as the sidewall of the melting zone, paving block and feed port.
Fused cast AZS 41# block is the highest grade fused cast AZS block. It has the best corrosion resistance to the glass liquid and low pollution potential. It is suitable for the parts that require super high resistance such as the electric melting furnace, throat, kiln dam, bubble block and the corner block of the feed port.
