ZM Series products

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.

ZM Series products产品概要

ZM Series Alumina fusion cast refractories are produced with highly purified alumina raw material which is melted at high temperatures of more than 2000℃ in an electric arc furnace and then allowed to cool and solidify in a mold. The products contain almost no matrix glassy phase, hence exhibit excellent minimal contamination to molten glass.

产品种类

ZM-U products are composed of β-alumina. They feature strong corrosion resistance to alkali vapor and hardly contain glassy phase and do not contaminate molten glass.

ZM-U products are best used in Breast wall and flat arch in the superstructure of glass furnaces.
