1.Description

Fire clay refractory brick is madefrom
flint clay clinker and binder,through high temperature sintering.Al2O3 content
is 30%-48%, SiO2 content is 50%-65%, and a small number of alkalimetals,
alkaline earth metal oxides, etc. Mineral composition is usuallymullite,
quartz and glass phase. Its refractoriness is 1580-1750°C,refractoriness under
load is 1250-1450 °C, line expansion coefficients is low, with goodthermal
shock resistance and strong ability to resist erosion acidslag.
