fire rated bricks
Introduction of fire rated bricks:
Clay brick refers to the Al2O3 content of 30%~40% aluminum silicate
material adhesive soil products.
Clay Brick is the use of 50% soft clay and 50% hard clay clinker, according to a certain
granularity requirements for ingredients, after molding, drying, in
the 1300~1400℃ of high temperature sintering. The mineral
composition of clay brick is mainly the impurities of kaolinite
(Al2O3•2SiO2•2H2O) and 6%~7% (potassium, sodium, calcium, titanium,
iron oxides). The sintering process of clay brick is mainly the
process of continuous dehydration and decomposition of kaolinite to
produce mullite (3Al2O3•2SiO2) crystallization. In the process of
sintering, the SiO2 and Al2O3 in the clay brick form the silicate
with the impurities and the low melting point of the eutectic,
which surrounds the crystallization around the Mullite stone.
Clay brick belongs to weak acidic refractory products, can resist
the erosion of acidic slag and acidic gas, clay brick thermal
performance is good, resistant to acute cold and hot. The
refractory degree of clay brick is equal to that of silicon brick,
up to 1690~1730℃, in the temperature range of 0~1000℃, the volume
of clay brick expands evenly with the increase of temperature, the
line expansion curve is similar to a straight line, the line
expansion rate is 0.6%~0.7%, and only about half of the silicon
brick. When the temperature is up to 1200 ℃ and then continues to
heat up, its volume will start to shrink from the expansion

Application of fire rated bricks:
It's widely used in blast furnaces, hot blast furnaces, furnace, a
steel barrels and pouring steel systems and homogenizing furnace,
heating furnaces, non-ferrous metal smelting furnaces, Furnaces for
the silicate and chemical industries, as well as chimneys and flue
for all thermal equipment.
