Frequently Asked Questions
What are the primary applications for these glass rollers?
These rollers are specifically designed for float glass annealing lehr lines, operating across various zones from high-temperature areas to cooling sections.
What materials are used for high-temperature zones?
For high-temperature requirements, we primarily use Cr25Ni20 and Cr18Ni8 stainless steel, which provide excellent heat resistance and prevent thermal bending.
Do you offer customization for specific dimensions?
Yes, all our rollers can be customized according to specific design requirements and dimensions provided by the client.
What is the maximum working temperature these rollers can withstand?
Our rollers are engineered to operate efficiently in temperatures ranging from 650ºC to 700ºC, depending on the material specification.
What are the benefits of using Graphite Ring Rollers?
Graphite Ring Rollers offer excellent thermal stability, fast heat dissipation, and a scratch-free surface for the glass, making them ideal for zones below 400ºC.
What manufacturing processes are involved?
Our production involves centrifugal casting or seamless pipe construction, followed by precise welding, heat treatment, machining, and high-grade polishing.
