The ZA Series oxidized AZS fusion cast refractories are manufactured from high-quality industrial raw materials by a long-arc fused cast and unique oxygen blowing melting process in a special electric arc furnace. This electric fused cast technology causes hardly carbon contamination from the electrode. The ZA series oxidized AZS fusion cast refractories have excellent corrosion resistance and low contamination to molten glass.
ZA-33 products have very small matrix glass phase exudation and are especially superior in preventing the contamination of molten glass. They have a low potential for stoning, blistering.
ZA-33 products are suitable for use in Superstructure of Melter. Sidewall and paving of Working End and Channel etc.
