Kiln refractory Fire Clay Brick is made from clinker clay by mixing, forming, drying, sintering
and machine pressing moulding with good resistance to corrosion and
abrasion, good thermal shock resistance, good spelling resistance,
high mechanical strength, good volume stability under high
temperature.
The mineral composition of heavy dense fire clay bricks mainly is
kaolinite(Al2O32SiO22H2O) and 6%~7% impurities (oxides of
potassium, sodium, calcium, titanium and iron). The firing process
of blast furnace refractory tiles is mainly due to the continuous
dehydration of kaolinite to form crystallization of mullite
(3Al2O32SiO2). SiO2 and Al2O3 in the yellow fire clay bricks form a
eutectic low-melting silicate with impurities during the firing
process, surrounding the mullite crystal.
The Fire Clay Brick made by CH refractories with various size and free mold charge to
meet different kiln applications. To be professional refractory
blocks manufacturer since 1984, CH refractories also can design
heat resistant bricks for sale, size according to your kiln drawing
for free, and suggest you the most economical refractory bricks
price for your kiln.
