Direct Reduction Behaviors of Composite Binder Magnetite Pellets in Coal-based Grate-rotary Kiln Process

Prospects for Coal-based Direct Reduction Process

Kobe Steel has developed coal-based direct reduction (DR) technologies, the FASTMET, FASTMELT and ITmk3 processes, which reduce carbon composite agglomerates (pellets or briquettes) on the hearth of a rotary hearth furnace (RHF). This paper outlines the features of each process, status of technical development and commercialization. Also described is the contribution of these technologies to en...

SOLID STATE REDUCTION OF CHROMITE IN HIGH CARBON FERROCHROMIUM-CHROMITE COMPOSITE PELLETS

Abstract: In this paper solid state reduction of high carbon ferrochromium-chromite composite pellets in the temperature range of 900-1350°C was investigated. A two stage reduction mechanism is proposed. The first stage is likely to be controlled by the chemical reaction with activation energy of 127.2kJ/mol. In the second stage, solid state diffusion of carbon through the reaction product ...
