High-temperature tube furnaces are normally equipped with fused silica roller for tempering furnaces at temperatures of 1200 °C and below. fused silica roller for tempering furnaces are characterized by fast heat conduction, high material purity and high density, which are especially suitable for gas protection or vacuum sealing.

The softening point temperature of quartz glass is about 1730 °C, which can be used for a long time at 1100 °C. The maximum use temperature can reach 1450 ° C in a short time.

In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially at high temperatures, it is impossible for any other engineering materials. Comparative.

The fused silica roller for tempering furnace has a very small thermal expansion coefficient and can withstand severe temperature changes. The quartz glass is heated to about 1100 °C and will not burst when placed in normal temperature water.

Fused silica roller for tempering furnaces have good light transmission properties in the entire spectral range from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach above 80.

The fused silica roller for tempering furnace has a resistance value equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures.

Corundum tubes are divided into several categories such as 95, 99. Corundum tubes have good characteristics and good wear resistance. 95 corundum tubes are suitable for 1000 degree tubular electric furnaces. 99 corundum tubes are suitable for tubular electric furnaces from 1200 degrees to 1600 degrees.
