Ceramic rollers for glass tempering furnaces possess unique properties similar to quartz glass, including a small thermal expansion coefficient, excellent thermal stability, and superior electrical insulation. Additionally, they offer high resistance to chemical attack and outstanding thermal conductivity, making them ideal for high-precision glass processing.
One of the most significant advantages of these rollers is their temperature-dependent strength. At 1100°C, the intensity increases by approximately 33% compared to room temperature, qualifying them as high-grade engineering ceramic materials.
