Abstract
The technology of stiff vacuum extrusion, invented by the company J. C. Steele & Sons, has been put to use in agglomerating iron-ore concentrate and fine coal. The extrusion products (brex) were subjected to high-temperature reduction. This article presents results from modeling the behavior of brex under conditions similar to the conditions that exist in the ITmk3® process. It is shown that ore-coal brex can serve as an alternative to the ore-coal pellets used for high-temperature reduction in rotary hearth furnaces.
