| 摘 要： | 以脱碳反应动力学规律及质量平衡为基础导出了电炉兑铁水条件下熔池脱碳速度与相应工艺参数之间关系的数学模型.与某钢厂100 t UHP电弧炉实际冶炼结果对比表明,该模型可以比较准确地预测熔池含碳量的变化和控制冶炼终点碳含量.研究表明,在高碳范围内脱碳速度与供氧流量成正比;在中碳范围内,其脱碳速度与熔池碳含量的平方根成正比;在低碳范围内脱碳速度与熔池碳含量成正比.用最小经济吹氧量曲线,即根据钢水碳含量降低相应递减吹氧量的吹氧方式,可以获得最佳的冶炼效果. |

| Abstract: | A mathematical model was developed to describe the relationship between the decarburization rate in bath and the operation parameters in the UHP electric arc furnace with hot metal charged,based on the reaction kinetic and mass balance.The model can be used to accurately describe the variation of carbon content in the bath and dynamically control the carbon content at the melting end.The calculated results were in good agreement with the production data of an 100 t UHP electric arc furnace.The simulated res... |
