Fire Clay Bricks 1400 degree heat proof bricks 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 1400 degree
heat proof bricks mainly is kaolinite(Al2O3·2SiO2·2H2O) 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 (3Al2O3·2SiO2). 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.
