Abstract:Theories and observations on the causes of disintegration of fireclay refractories in blast furnaces are given and a process is developed for improving high iron clays for this use. The disintegration of refractories in blast furnace linings is initiated by alteration in the iron spots. Ferric oxide is reduced to ferrous oxide at 500°C and hastens the cracking of 2CO to CO2+C1 the carbon being retained by the lining. When Fe2O2 is converted to Fe3O4 the brick will not disintegrate.
