Failure Mechanism Of Alumino Silicate Refractories In Anode Baking Furnace

Anode baking furnaces is an integral part of aluminium industry. In this furnace, anodes are baked to use in electrolytic reduction. Depending on the design either open top or closed top furnaces are employed. To-date- alumino-silicate refractories are the choicest material due to their low cost, low creep under compression, high resistance to thermal cycle, carbon monoxide disintegration, and alkali attack. This paper deals with failure mechanism of such type refractories.
