COREX熔融还原炼铁技术

COREX SMELTING REDUCTION IRONMAKING TECHNOLOGY

ＣＯＲＥＸ熔融还原炼铁工艺用非炼焦煤直接炼铁，流程短、投资省、成本低、污染少、铁水质量好，过程煤气可用于生产海绵铁，成为当代冶金工业的前沿技术。本文分析了ＣＯＲＥＸ工艺的特点，原、燃料的性能要求，技术经济指标，讨论了其发展前景和进一步研究完善的方向。

The COREX smelting reduction ironmaking technology has been known as an advanced technology of metallurgical industry presently due to the use of noncoke coal,shorter production route,lower investment and cost,less pollution and good quality of hot metal and the use of off gas for production of sponge ironThis paper concerns the COREX's features,the requirements of raw materials and fuels,and the technological indexes of COREX production processThe further development and improvement of COREX technology is discussed
