通过磁再约束等离子弧切割陶瓷实验 ,考察约束磁场对等离子弧特性、切割质量及无渣切速的影响规律 ,分析了所用磁约束装置的性能和方法的局限性 ,指出了进一步研究高质量约束磁场装置的必要性。 The effect of the confining magnetic field on the characteristics of plasma arc, the cutting quality and the non-slag cutting speed was investigated through the magnetic re-constrained plasma arc cutting ceramic experiment. The limitations of the performance and method of the magnetic restraining device used were analyzed. It was pointed out that the further study of high-quality restraint Necessity of magnetic field device.
