Sell Fused Silica Ceramic Roller

详情

Usage：Carrying and transmission of glass in glass horizontal tempering furnace
Feature：Using high-purity fused quartz as raw material, produced by Foreign advanced forming and processing technology，High bulk density, high strength, small thermal expansion, good thermal shock resistance, high dimensional accuracy, high temperature deformation, long life, glass non-polluting, high quality, affordable and can replace imported products.

Character：（1）Very low coefficient of thermal expansion, therefore has a strong thermal shock resistance;（2）Excellent corrosion resistance, the surface of the product is very durable;（3）With the chemical composition of high purity, its contact with the product composition and surface quality is not contaminated.（4）Excellent ceramics physical performance, stability, small size of the error in the temperature of the ambient temperature and high temperature performance, excellent surface quality. Solid shaft, each marked with the number, quality inspection reports, with traceability.
●Very low coefficient of thermal expansion, a strong thermal shock resistance, high temperature deformation;
●Raw materials of high purity and excellent chemical physical properties;

●Precision processing technology, precise dimensional accuracy;
●Reliable shaft connection technology.
