    Abstract

    Metallized pellets produced under a wide range of different reduction conditions were sectioned and examined microscopically. The structures observed can be related to the degree of reduction and the conditions of time, temperature, and fixed carbon/iron (C/Fe) ratio under which reduction occurred. The mechanisms of reaction under different sets of these conditions are discussed, and the role played by slag in the development of pellet structure, and in hindering reduction in certain instances, is considered.
