Product Description
Silica Firebrick for Coke Furnace Building
Silica Firebrick for Coke Furnace Building Silica content is above 92%. True density 2.35g/cm3. It is resistant to acid slag. Higher high temperature strength. The initial temperature of load softening is 1620~1670℃. In high temperature for a long time without deformation. Low thermal shock stability (water heat exchange is 1~4 times) with natural silica as raw material, plus an appropriate amount of mineralization agent, to promote the conversion of quartz in the billet into, scale quartz. It is slowly fired at 1350~1430℃ in reducing atmosphere. When heated to 1450℃, about 1.5~2.2% of the total volume expansion, the residual expansion will make the cut joints close, to ensure that the masonry has good air tightness and structural strength.
Characteristics of Silica Firebrick for Coke Furnace Building:
1.Good acid and erosion resistance, powerful anti high-temperature strength.
2.Soften melting temperature is 1620~1670 °C.
3.Low thermal shock resistance.
4.Natural silica as raw material, plus regular mineralizer.
5.Ensure good bonding and structural strength of furnace.
6.Good heat resistance and long service life.
