Fused Silica Roller

Quartz ceramic rollers can be used as horizontal conveying rollers in production lines such as horizontal tempering furnaces and silicon steel heat treatment. Quartz ceramic rollers have the following advantages: high density, high strength, small deformation at high temperatures, smooth and delicate roller tables, and small radial runouts. Therefore, it is widely used to carry and transport glass in horizontal tempering furnaces.
