■ Application:
Fused silica ceramic rollers are made from high-purity fused silica and are used in high-temperature applications such as glass production. The Silica roller for glass furnace have excellent thermal stability and can withstand temperatures up to 1200°C. Fused silica ceramic rollers are also highly resistant to corrosion, chemical attack, and wear, making them ideal for use in harsh environments.
The fused silica roller for kilns are commonly used in glass manufacturing processes such as float glass production, where they are used to support and guide the glass as it is formed and cooled. The silica roller for glass furnace are also used in the production of solar panels, optical fibers, and other high-tech materials.
The fused silica ceramic annealing roller are available in various sizes and shapes to meet different application requirements. The silica roller for glass furnace can be customized to fit specific equipment and are often used in combination with other ceramic components to create a complete high-temperature system.
