Molding and production rules of silicon brick
Silica content above 94%. True density 2.35g/cm3. It is resistant to acid slag erosion. High temperature strength. Load softening starting temperature 1620 ~ 1670℃. Long-term use at high temperature without deformation. Low thermal shock stability (heat exchange in water is 1 to 4 times) Natural silica is used as raw material, and an appropriate amount of mineralizing agent is added to promote the conversion of quartz in the billet into quartz.
.
It is slowly fired at 1350 ~ 1430℃ in a reducing atmosphere. When heated to 1450℃, there is a total volume expansion of about 1.5~2.2%, and this residual expansion will make the cut joints close to ensure that the masonry has good air tightness and structural strength.
