PROPERTIES DEPENDENCE OF ALUMINA REFRACTORIES ON THE KIND OF THE USED ALUMINA - EITHER SINTERED OR FUSED

摘要

The properties of the pressed alumina refractory products made of sintered and white fused alumina in the same production condition have been contrastively analyzed. Both types of refractories have similar open porosity, apparent density and cold crushing strength, but the refractory made of sintered alumina has higher thermal shock resistance whereas refractory made of white fused alumina has higher creep resistance. Both types have similar corrosion to melted steel.
