电炉采用大比例直接还原铁冶炼技术分析

Analysis of EAF melting technology with large proportion of direct reduction iron

对中东某钢铁企业电炉采用大比例直接还原铁冶炼的技术特点进行分析,实际生产表明:电炉采用大比例直接还原铁冶炼时采用大留钢量、炉顶连续加料、100%直接还原铁连续冶炼、泡沫渣冶炼、熔池搅拌等技术均有利于生产组织及钢水质量。

The technology characteristic of EAF melting with large proportion of direct reduction iron were analyzed in one steelmaking plant in Middle East. And the real production indicated that EAF melting with large proportion of direct reduction iron should adopt large hot heel, continuous charging at top, 100 % direct reduction iron continuous melting, melting with foamed slag, bath stirring, which were benefit for organization and liquid steel quality.
