Fused Silica Roller
|
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. |
