The Use Of Silica Brick In The Glass Furnace

Since the silica brick has low price, high purity, high softening temperature under load, no pollution to glass liquid and good resistance to R2O gases and aicd gases, it is widely used in the crown of the glass furnace, the upper part of the suspended wall, the back wall and the front wall.

The SiO2 content in the silica brick used in the glass furnaces should be controlled. And it should be mainly composed of cristobalite. For large glass furnaces and oxy-fuel glass furnaces, refractory materials with high purity, good creep resistance and good corrosion resistance are used.

Since the advent of brick, there are three types of brick. The first is the common silica brick. the second is high quality silica brick. the third category is improved high quality silica brick.

With the development of glass mleting technology, silica bricks with better performance are required.
