Studies in the Sintering Permeability and Pellet Strength of Australian Hematite Ores

Abstract

Sintering of fine iron ores is achieved by causing a combustion zone to move progressively through a suitably prepared porous bed of the ore in which is incorporated a small quantity of a fuel such as finely crushed coke. The agglomeration of the ore particles takes place by their complete fustion and/or the formation of a partial slag bond between them. In general the faster the combustion zone passes through the bed the faster will be the sint-ering rate.
