Fused silica ceramic hollow roller

Quartz ceramic roller is used in glass horizontal toughening furnace and metallurgical strip heat treatment furnace to support and transfer glass or metal strip. High strength, good thermal shock stability, high machining accuracy, high temperature no deformation, long service life. Stable and reliable quality, can replace importing products. Products of various specifications and models below 300X3800mm can be processed according to the requirements of user drawings.
