摘　　要：通过对真空电弧重熔炉工艺过程的分析,根据冶炼实际情况,提出了一些有助于控制冶炼目标的局部策略,如弧长控制、熔速控制、解耦控制等。实际应用表明,当熔炼过程出现各种特殊情况时,采用这些局部策略能得到更好的控制效果。Based on analysis for vacuum arc remelting process and according to actual melting condition, some partial strategies which is helpful for control of melting aim were presented, for example, arc length control, melting speed control, decouple control and so on. Practice application shows that better control effect can be obtained by use of those partial strategies when special event happens during melting.
