Features of Refractory silica bricks for vertical kiln:
1. high volume density of 2.34 g/cm3
2. high SiO2 content of 96%
3. low iron content of 0.8%
4. low melting point of 5%
Applications of Refractory silica bricks for vertical kiln:
Because of the high temperature resistant performance significantly, long service life characteristics (as long as more than 3 years) of refractory silica brick for verticalkiln, it can significantly improve the quality ofproducts, so the refractory silica bricks are widely used in all kinds of glass furnace melting department, regenerator and other important parts.
