摘　　要：针对电渣重熔生产过程的高能耗问题,在传统电渣重熔系统的基础上,提出了振动电极电渣重熔方法以提高熔化效率。并以振动电极电渣重熔方法的试验数据为基础,建立了基于数据驱动的样条变换非线性偏最小二乘回归数学模型。通过Matlab仿真和试验结果分析,与无振动情况相比,该方法能有效地提高熔化效率,同时验证了该模型的有效性。Aiming at the high energy consumption of traditional production process of ESR system,vibra-ting electrode remelting method was proposed to improve the melting rate.Based on the experimental data of vibrating electrode method,a model was built up on the basis of a theoretical research of partial least-squares regression spline transformation .Compared with no vibration,the simulation result re-veals that the method can improve effectively the melting rate,and prove the validity of the model.
