YUFENGREC Fused Silica Ceramic Roller are widely used for the production of the raw glass and glass deep processing ,We combines outstanding foreign ceramic art from the actual precess of the team of experts as well as domestic famous university experts and scientific theory ,the formation of a systemic production system . Every production series of quartz ceramic rollers with excellent variety of performance indicators ,fully guarantee the quality of products, the maximum to meet in the used of many types of glass enterprises
Key Features
*Use high purity fused silica ,with low thermal expansion coefficient and good thermal shock resistance .
*The unique formula of raw material and the slurry processing to ensure the anti-bending strength of the roller.
*Mature processing technology,complete and sophisticated equipment to ensure a smooth surface ,delicate,minimal runout ,excellent performance of the wear resistance .
*Exquisite original steel bushing ,a mature shaft head structure design ,completely solve the sleeve loose shedding .
*Sleeve using the latest coating antirust technology ,aesthetics ,durability .
*Long working life ,good stability
*Any size can be customized , can produce all kinds of Φ 15- Φ360 mm quartz ceramic rollers ,to meet all kinds of kiln needs .
Typical Applications
*Tempered furnace
*Float glass production line
*Annealing furnace
* Metal heat treatment furnace etc …
