熔融还原炼铁原是指“含碳铁水在高温熔融状态下与熔化的铁矿石产生反应”的新工艺,后随着实际工作的进展,泛指用非焦煤直接生产热铁水的工艺均称为熔融还原。这种理念早在100多年前就被冶金学家提出,但到1989年才开始得到工业生产应用并成为当代钢铁工业前沿技术之一。这是因 Melting reduction of iron is the original “carbon-containing molten iron at high temperature molten molten iron ore reaction” new technology, with the actual progress of work, refers to the non-coking coal production of hot metal directly referred to the process For the melt reduction. This concept was proposed by metallurgists more than 100 years ago, but it was not until 1989 that it began to be used in industrial production and became one of the leading technologies in the contemporary steel industry. This is because
