淮钢短流程生产线的技术创新

Technical Innovation of Compact Production Line at Huaisteel

淮钢超高功率电炉-炉外精炼—连铸—连轧短流程生产线,通过采用铁水热装、强化用氧、低铝洁净钢精炼和连铸坯热送热装等主要工艺技术措施,取得了明显的增产节能效果。自投产以来,钢质量逐步提高,电耗、电极耗却逐年下降,冶炼时间逐年缩短。

Great progress in production and energy saving has been achieved in the compact production line of 70 t UHP. EAF-70 t LF-150 mm× 150 mm CC-18 strands CR at Huaigang with the technologies of hot metal charging, increasing oxygen use, low Al2O3 clean steel refining proved, and power consumption, electrode consumption and production line put in operation. and hot charging rolling. The product quality is imtapping to tapping time are reduced yearly since the
