摘要
分析了中国钢铁制造流程的特点,考察了直接还原技术在中国的发展现状,结合中国资源条件提出了直接还原技术在中国的发展方向,设想了一个180万t/a规模壳牌煤气化与HYL/Energiron竖炉生产直接还原铁的联合工艺流程,描述了联合工艺的主要参数和技术经济指标,为煤制气生产直接还原铁的工程化提供方案参考。
The feature of iron and steel manufacture process in China had been analyzed and the present status of direct reduction technology in China had been reviewed at first.The trend of direct reduction technology development has been given with consideration of natural resources in China.A 1.8 Mt/a combined process of Shell coal gasification and HYL/Energiron direct reduction shaft furnace has been proposed as an example.The parameters,technical and economic index of new process have been described as well.This article provided a scheme for the engineering of direct reduction using synthesis gas as reducing agent.
