摘要： A method for manufacturing reduced iron, wherein iron oxide in a pulverized state is subjected to high-temperature reduction. A mixture of pulverized iron oxide and a pulverized solid reducing agent are molded as iron plates, placed on a bed in a reducing furnace, and reduced at a constant temperature not lower than 1100 DEG C. Since the plate type molded product can be obtained only by molding a raw material mixture by a roller, so that the time required to process a raw material is very short as compared with that required for pelletizing process. A plate type molded product is placed on a bed via feed chute, and a drying step is not therefore required. This method can be carried out easily by the subject reduced iron manufacturing apparatus. When the reduced iron obtained by this method is introduced unter a high-temperature condition into a vertical furnace or a refining melt-reducing furnace and melted with a high thermal efficiency, a high-quality hot metal can be obtained.
摘要翻译：还原铁的制造方法，其中粉碎状态的氧化铁进行高温还原。将粉碎的氧化铁和粉碎的固体还原剂的混合物作为铁板模制，放置在还原炉的床上，并在不低于1100℃的恒定温度下还原。由于仅能获得板型模制产品通过用辊将原料混合物成型，使得处理原料所需的时间与造粒工艺所需的时间相比非常短。板式成型品通过进料槽放置在床上，因此不需要干燥步骤。该方法可以由被还原铁制造装置容易地进行。当通过该方法得到的还原铁在高温条件下引入垂直炉或精炼熔融还原炉中并以高热效率熔化时，可以获得高品质的铁水。

摘要： The invention relates to a continuous casting method and a continuous casting apparatus, in which a non-solidifying cast piece is appropriately subjected to rolling by rolls while being continuously drawn by support rolls. According to this method, a non-solidifying rolling strain and a bulging strain are reduced whereby a total accumulated strain is suppressed to be made small, and thin cast pieces free of internal crack can be manufactured even in non-solidifying rolling under the condition of high speed casting. In the apparatus, a misalignment strain is suppressed and non-solidifying rolling of cast pieces is easily performed, and modification to thickness of cast pieces can be carried out without stopping the apparatus during operation.
