摘　　要：试验包括冷流试验和燃烧试验两部分,记录两部分试验的试验数据和流场形态。通过冷流纹影试验与点火燃烧试验的切割氧分布形态、切割氧风线长度的比较,分析出割嘴切割性能的变化规律,为改进和提高大厚度割嘴切割能力提供理论基础和试验依据。The experiments include the cold flow experiment and combustion experiment.The experimental data and flow state were recorded in experiments.By comparing the oxygen flow state and its length in both experiments,the variation of cutting performance of cutting torch was analyzed,which provides the theortical basis and experimental data for improvement on cutting ability of cutting torch for heavy thick plate.
