Brief Introduction


Fused silica rollers are widely used for glass manufacturing  glass transformation, steel processing and non-ferrous metal processing.

Fused silica rollers with high-quality, high-purity fused quartz as raw material, the introduction of foreign advanced
production technology from forming and processing. Horizontal glass tempering furnace is a key component to support and transfer glass. Fused silica rollers has excellent physical properties to ensure that work at ambient temperature and high temperature performance and stability.
