Analysis of Three Dimensional Structure of Iron-ore Sintercake

Abstract

Three-dimensional structure of iron-ore sintercakes, which are prepared by pot test (90 mm-dia.; 400 mm-height) with varying the location in bed and Al₂O₃ content, has been investigated with the use of an X-ray CT and a three-dimensional image analyzing system. It has revealed that sintercake basically consists of a continuous plate-shaped matrix including numerous closed pores of under-2 mm diameter and a continuous intercommunicating pore. Moreover, the shape of the matrix/pore in the lower part of the bed becomes round, though few changes by Al₂O₃ can be detected.
