摘　　要：介绍了淮钢70 t超高功率电炉-LF炉外精炼-连铸-连轧短流程生产线采用铁水热装技术、强化用氧技术、低铝洁净钢技术和铸坯热送热装技术所取得的节能效果及品种开发和产品质量情况。目前该生产线年产钢已达74万t,优特钢比达到97.1%,冶炼总电耗(EAF+LF)降到140 kW.h/t以下,冶炼周期在43 min左右。The results of energy saving and consumption reduction and product quality on the compact production line of 70 t UHP EAF-LF-CC-CR with technology of hot molten iron charging, strengthening uses of oxygen, low Al2O3 content clean steel and hot charging of continuous casting billet at Huaisteel is introduced. Now this production line yearly produces steel 740 000 tons, quality steel ratio achieves 97.1%, total electricity consumes （EAF＋LF） falls to 140 kW · h/t below and tapping to tapping time is about 43 minutes.
