Refractory castable drying and baking control process
The difference between silicon brick and semi-silicon brick
Silica brick is refractory product with SiO2 content above 92%. The higher the content of SiO2 in silica raw materials, the higher the refractoriness of products, the ability of acid erosion resistance is very strong.
The first stage is in the temperature from room temperature to 100 degrees Celsius, generally natural drying temperature is about 40 degrees Celsius. But the fastest dehydration temperature of hydrated refractory castable is 50-60℃.
