Abstract

本発明は、回転炉床炉などの還元炉から高温で排出された還元鉄を用いて良好なホットブリケットマシンの製造を行うことが可能な方法を提供することを目的とする。この方法は、前記高温還元鉄を冷却しかつその温度を６００°Cを超えかつ７５０°C以下である熱間成形適正温度に制御する温度制御工程と、当該熱間成形適正温度をもつ高温還元鉄をブリケットマシンにて熱間成形することによりホットブリケットアイアンを生成する工程とを含み、前記温度制御工程は、内周面に螺旋状に送り羽根が設けられた回転ドラムを略水平に保持することと、該回転ドラム内を不活性ガスにて非酸化性雰囲気に維持しつつ、前記高温還元鉄を該回転ドラム内に装入して該回転ドラムを回転させることにより該回転ドラム中を通過させることと、前記高温還元鉄が前記回転ドラム中を通過する間に該回転ドラムの外周面を冷却流体と接触させて冷却することにより、該還元鉄の温度を前記熱間成形適正温度にするように当該還元鉄を間接冷却することとを含む。
