Frequently Asked Questions (FAQ)
What are the primary applications for these rollers?
These rollers are specifically designed for the float glass annealing lehr production line, covering various temperature zones from the high-heat entry to the cooling stages.
What materials are used for high-temperature resistance?
We primarily use high-grade alloys such as Cr25Ni20 (25/20) and Cr18Ni8, as well as specialized heat-resistant fiber and graphite materials for different zone requirements.
How do you prevent thermal bending in rollers?
Through the use of centrifugal casting and seamless pipe processing combined with precise heat treatment, our rollers maintain stable dimensions and resist thermal bending even under long-term high-temperature use.
Can the roller dimensions be customized?
Yes, all rollers including LOR, lehr, and composite rollers can be manufactured according to customized specifications and specific industrial dimensions.
What are the benefits of using Graphite Ring Rollers?
Graphite ring rollers offer small thermal expansion, no deformation, and ideal hardness that ensures the glass surface remains scratch-free while facilitating fast heat dissipation.
What is the maximum working temperature for these products?
Our standard high-temperature rollers are designed to operate efficiently within the 650ºC to 750ºC range, depending on the material and specific application zone.
