ZA系列氧化法锆刚玉产品是采用优质工业原料、使用特制电弧炉、经过长弧熔融和独特吹氧工艺制成的。

ZM 产品根据其晶相结构分为 ZM-G(α β- 氧化铝 ) 和ZM-U(β- 氧化铝 ) 两大类，再按外观质量规格和浇铸方式做进一步的分类，这些分类可以满足 ZM 系列产品在玻璃窑炉不同部位的使用要求。

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.

ZM Series products can be divided into ZM-G(αβ- alumina) and ZM-U(β-alumina) according to their crystalline structure, and use the appearance, quality, specifications and casting methods for further classification. This classification of ZM Series products can satisfy the operating requirements in different position of glass furnaces.
