Products preface:
Choosing the fined high purity fused quartz as material ,on the basis of introduction the foreign advanced molding and processing manufacturing cline, Our quartz ceramic roller is used for the key part component of the floating glass furnace,which may bear and transit the glass.
Properties
*With extremely low coefficient of thermal expansion (0.6x10-6/°C),therefore it greatly strenthen thermost ablility, dose not distort under high tempereture,even in the oxidized atmosphere it may undergo the teperature fierce diversification within 1100°C environment.
* The extremely ceramic physical properties guaranteed the stable performance under the ambient tempereture and the operating tempereture environment.
* With the reliable axle neck joint technology ,the serial number and quality examination report.
* With the fine inoxidizability , the product surface owns extremely durable properties.
* The precise processing craft,precise size precision
* High chemical purity that does not pollute the glass and silicon liquid.
* Low thermal conductivity.
* High electrical insulation.
* Smooth surface for resistance to corrosion.
* High precision and big dimensional products are available.
Product line: roller for horizontal tempering furnace, transition roller and annealing roller for float glass line,crucible for ingotting polysilicon etc.
