摘要： Method and system for producing metallic nuggets includes providing reducible mixture (e.g., reducible micro-agglomerates; reducing material and reducible iron bearing material; reducible mixture including additives such as a fluxing agent; compacts, etc.) on at least a portion of a hearth material layer. In one embodiment, a plurality of channel openings extend at least partially through a layer of the reducible mixture to define a plurality of nugget forming reducible material regions. Such channel openings may be at least partially filled with nugget separation fill material (e.g., carbonaceous material). Thermally treating the layer of reducible mixture results in formation of one or more metallic iron nuggets. In other embodiments, various compositions of the reducible mixture and the formation of the reducible mixture provide one or more beneficial characteristics.

摘要翻译： 用于生产金属块的方法和系统包括在炉膛的至少一部分上提供可还原混合物（例如，可还原的微团聚物;还原材料和可还原的含铁材料;包括诸如助熔剂的添加剂的可还原混合物;压块等） 材料层。 在一个实施例中，多个通道开口至少部分地延伸穿过一层可还原混合物以限定多个形成块的可还原材料区域。 这种通道开口可以至少部分地填充有熔核分离填充材料（例如含碳材料）。 热处理可还原混合物层导致形成一个或多个金属铁块。 在其他实施方案中，可还原混合物的各种组合物和可还原混合物的形成提供一种或多种有益特性。
