Hot Sale 1710C Refractory High Strength and High Silica Brick For
1710C Refractory High Strength and High Silica Brick is a widely used for coke oven, hot blast stove, acid steel making
furnace and glass melting furnace.
1710C Refractory High Strength and High Silica Brick can be manufactured according to customers' different requireents.
1710C Refractory High Strength and High Silica Brick generally use
crystalline quartzite or silica sand as raw materials, and the
mineral composition is: phosphorite 78% to 86%, cristobalite 13% to
15%, and quartz 4% to 7%. Add combustible materials to the
ingredients, such as coke, sawdust, anthracite, carbonized rice
husk, or use gas foaming to form a porous structure. 1710C
Refractory High Strength and High Silica BrickPrice are
heat-insulating silicon refractory products with a SiO2 content of
more than 90% and a bulk density of less than 1.2. The
refractoriness and softening temperature under load are not much
different from ordinary silica bricks with the same composition.
However, due to the many pores, the compressive strength, slag
resistance, and corrosion resistance are not as good as ordinary
silica bricks, but the thermal shock resistance has been improved.
It is similar to the production process of ordinary silica bricks.
Some mineralizers (CaO, Fe2O3) are added to the ingredients to
promote the conversion of quartz, and pulp waste liquid is used as
a binder to make the bricks have a certain strength. When using
coke or anthracite as combustible additives, because the ash will
be brought into Fe2O3 and Al2O3, there is no need to add iron
scales in the ingredients. When the siliceous Insulating silica
bricks are fired, a strong oxidizing flame should be maintained
before 1200°C to make the additions burn out completely.
1710C Refractory High Strength and High Silica Brick Features
1. Good acid and erosion resistance, powerful anti high-temperature
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.
