摘要： A hearth furnace 10 for producing metallic iron material has a furnace housing 11 with a drying/preheat zone 12 capable of providing a drying/preheat atmosphere for reducible material, a conversion zone 13 capable of providing a reducing atmosphere for reducible material, a fusion zone 14 capable of providing an atmosphere to at least partially reduced metallic iron material, and optionally a cooling zone 15 capable of providing a cooling atmosphere for reduced material containing metallic iron material. A hearth 20 is movable within the furnace housing 11 in a direction through the drying/preheat zone 12, then the conversion zone 13, then the fusion zone 14, and then the cooling zone 15. A separation barrier 30 is positioned within at least a portion of the conversion zone 13, the separation barrier 30 separating the conversion zone 13 into a combustion region 32 and a reducing region 31 with the reducing region 31 adjacent the hearth 20 and the combustion region 32 adjacent the reducing region 31 and spaced from the hearth 20.
