摘要： The present invention is directed to a method of producing metallic iron,
comprising: supplying a formed raw material comprising a carbonaceous reductant and a substance containing iron oxide onto hearth refractories of a moving hearth type reduction melting furnace; heating the formed raw material to subject the iron oxide to reduction melting; and ejecting and collecting resulting metallic iron after cooling the metallic iron, wherein a deposit layer containing slag produced in the reduction melting process is formed on the hearth refractories, thereby protecting the hearth refractories while producing the metallic iron.摘要翻译： 本发明涉及生产金属铁，的方法，包括：供给形成的剃刀含有碳质还原剂和含氧化铁的到移动的炉床式还原熔化炉的炉床耐火材料的物质; 加热所形成的原料，以受试者氧化铁还原熔融; 和喷射和收集所得金属铁冷却的金属铁后，worin沉积层包含In的还原熔融过程中产生的炉渣形成在炉床耐火材料，从而保护炉床耐火材料而制造金属铁。
