Structure and properties of strip made from iron oxide superconcentrate by a direct route

Abstract

A technique for producing steel strip from organically bonded iron oxide superconcentrate by a direct route involving hot and cold rolling has already been established. The present paper deals with the structure and properties of the cold-rolled and annealed strip, and compares them with those of conventional materials. The structure of the direct strip is entirely different from that of conventional material and consists of a pure iron matrix containing a high proportion of finely divided impurity inclusions, uniformly distributed. Special consideration is given to the size range and distribution of the inclusions, and to the drawing properties of strip.
