| 内容記述 | In the plasma cutting process, the arcjet with high specific energy is required to get good cut quality in the dross-free cutting. For this purpose, it is necessary to stabilize the arc with gas flow rate lower than the conventional torches. The present paper discusses the nozzle shape that effectively stabilizes the arc by the swirl flow. The pressure measurement inside the large-scale model-nozzle indicates that the nozzle shape can be optimized to create a large pressure gradient for the arc stabilization with a constant gas flow rate. The metal cutting test by the nozzle with optimum shape shows a remarkable improvement in arc stabilization. |
