本文评述了各种直接还原法的发展。对常规的高炉炼铁而言,直接还原也是一种可供选择的炼铁方法。讨论了矿石的利用和供应以及能量的供给和消耗情况。概述了直接还原法的发展潜力。对直接还原生产能力的进一步发展作了估计。就设备能力和海绵铁的实际产量进行了比较。计算了生产海绵铁与地区有关的成本。
This article reviews the development of various direct reduction methods. For conventional blast furnace ironmaking, direct reduction is also an alternative ironmaking method. Discusses the utilization and supply of ores and the supply and consumption of energy. The potential of direct reduction is outlined. The further development of direct reduction production capacity was estimated. The capacity of the equipment and the actual production of sponge iron were compared. Calculate the area-related costs of producing sponge iron.
