摘要
分析激光切割的工艺特点和质量指标,讨论激光功率、切割速度、激光聚集焦点位置等对切割质量的影响,进而采用激光切割机,不断地进行切割试验,从而确定了一组可以有效切割300MW汽轮发电机风道板结构中0.65mm厚65TW400硅钢风道片的切割参数。
The technological characteristics and quality index of laser cutting are analyzed. The effects of laser power, cutting speed and focus position of laser aggregation on cutting quality are discussed. The laser cutting machine is tested repeatedly to determine a set of cutting parameters that can be used effectively to cut a duct plate of 0.65 mm thickness in a 65TW400 silicon steel duct structure of a 300 MW steam turbine generator.
