Improve quality and reduce costs
By significantly reducing the accumulation of sulfate, it is possible to achieve an improvement in the quality of the glass and a reduction in the scrap rate as compared with the steel roller.
The fused silica roller has an extremely low thermal conductivity and is the best choice for controlling the annealing process, enabling low-deformation glass without microcracks and low stress or even glass ribbon.
ÃÂ·Smooth surface, easy to treat tin or tin oxideÂ
The fused silica material is characterized by its very stable oxide form and is non-wetting compared to metallic elements.
Due to specific surface characteristics, tin or tin oxide carried by process variations does not react with the surface of the roller and can be easily removed.
ÃÂ·The advantages of annealing rollers
Has excellent thermosetting properties. There is no deflection during thermal intervention over the entire temperature range.
The diameter of the roller table is constant, ensuring a consistent rotation speed.
