Description of Fused Silica Castable:
With the characteristics of low thermal expansion coefficient, low thermal conductivity, and energy saving, fused silica castable can reduce the thickness of the lining body. In addition, it also has the characteristics of high refractoriness, good volume stability at high temperature and good thermal shock resistance.
