铁矿石熔融还原法的现状［日］植村健一郎１前言直接利用煤的炼铁技术现在再次引起人们的注目。通常炼铁法（从铁矿石还原铁的过程）一般有熔融状态炼铁的高炉法和经过熔融状态的固体冶炼出金属铁（含铁率≥９０％）的直接还原铁（ＤＲＩ＝ＤｉｒｅｃｔＲｅｄｕｃｅｄＩｒ...
Current status of iron ore smelting reduction method [1] Kenichiro Uemura 1 INTRODUCTION The direct use of iron smelting technology now attracts attention again. Usually, the ironmaking method (the process of reducing iron from iron ore) generally includes a blast furnace method of melting ironmaking and a direct reduction iron (DRI = DirectReduced Irr) of smelting a metal iron (iron content≥90%) through a solid in a molten state. ..
