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
The raw material for making silicon bricks is silica. The higher the SiO2 content of silica raw materials, the higher the refractoriness. The most harmful impurities are Al2O3, K2O, Na2O, etc., which seriously reduce the refractoriness of refractory products
