    70t超高功率電弧爐冶煉工藝優(yōu)化

    Melting Process Optimization of 70t UHP Electrical Arc Furnace

    • 摘要: 攀鋼集團成都鋼鐵有限責(zé)任公司引進(jìn)的70t超高功率電弧爐在試生產(chǎn)過程中存在冶煉周期長、電極消耗高、RCB槍和爐壁水冷板易燒壞漏水、爐齡偏低、鋼液中氣體含量偏高等問題。通過分析找出了產(chǎn)生問題的原因,提出了優(yōu)化RCB槍供氧制度、冶煉配電制度等相應(yīng)解決措施,取得良好效果。

       

      Abstract: Some problems existed with the 70 t UHP EAF as imported by Pangang Group Chengdu I&S Co. Ltd.during the trail operation period,including rather long melting cycle,high electrode consumption,water leakage as caused by frequent damage of the RCB lance and the water cooled panels by burning,low campaign and high gas contents in the liquid steel,etc.Owing to relevant investigations,causes for the said problems are identified,based on which corrective actions like optimizing the RCB oxygen-feeding schedule and the melting power-supply schedule have been taken,resulting in satisfactory effectiveness.
