The shaft reduction process involves complex phenomena of momentum, energy and mass transfer. Usually, the direct reduction of shaft furnace is divided into 3 zones: the reduction, transition and cooling zones. In the reduction zone, the major reactions of solid gas are mainly controlled by the heat supply and local gas composition.
