电弧炉连续炼钢工艺新进展 国际钢公司开发的电弧炉连续炼钢工艺,以连续加料和连续满功率操作为特征。自从第一套电弧炉连续炼钢工艺在美国诺搁公司达林顿钢厂投产以来,操作结果令人满意,显示出具有强大的生命力。 连续炼钢系统的电弧炉内始终保持着熔池,即使出钢完毕时,也残留少量的钢水,使加入的废钢迅速地熔化;钢水的温度保持在一定的温度范围内,可确保钢水和渣之间稳定的平衡;冶炼连续进行,钢水在不断沸腾,所以整个熔池的成分和温度都比较均匀;在冶炼中的任何时候,都能精确地控制泡沫渣。
New Progress in EAF Continuous Steelmaking Process The EAF continuous steelmaking process developed by International Steel Corporation is characterized by continuous feeding and continuous full power operation. Since the first EAF continuous steelmaking process was commissioned at the Novo Nordisk plant in the United States, the results were satisfactory and demonstrated to be very viable. In the continuous steelmaking system, the arc furnace keeps the molten pool all the time. Even if the tapping is completed, a small amount of molten steel remains, which causes the added scrap to melt rapidly. The temperature of the molten steel is maintained within a certain temperature range to ensure the molten steel and slag The balance between the stable; smelting continuous, continuous boiling of molten steel, so the composition and temperature of the molten pool are more uniform; at any time in the smelting, foam slag can be precisely controlled.
