Description
Our Silica Brick for Glass Furnace is a siliceous refractory product which is used to build high-temperature parts of glass furnace, but does not contact with glass liquid. Because of its low cost, high creep resistance and low glass pollution, it is widely used in the crown of glass furnaces. At the same time, it has a compact structure, is not easy to be wetted by molten glass, and has low reaction with glass, can be used in various high temperature environments, and maintain good processing effect.
Features
This Silica Brick for Glass Furnace has stable volume at high temperature, low creep rate, and can maintain deformation at 1600 ° C. At the same time, its main component is SiO2. If massive or surface droplets appear during use, the quality of glass liquid will not be affected. During processing, when its surface is eroded by the gas containing R2O in the glass liquid, a smooth metamorphic layer will be formed to protect it.
