【摘要】 将激光切割技术应用于钢铁中氮元素含量分析的试样加工过程中。分别使用激光切割法与传统的冲孔法加工钢铁样品,并比对加工效果的属性,发现激光切割法在一次加工合格率,试样形貌,加工钢种的通用性方面均优于传统的冲孔法。用激光切割法加工出的试样,其氮元素含量分析结果的准确度和精密度均能够满足生产需要。因此,激光切割法能够用于制备钢铁中氮元素含量分析的试样。更多还原

【Abstract】 Laser cutting technology was applied to sample processing of nitrogen content analysis in steel. Laser cutting method and traditional punching method are used to process steel samples, and the attributes of the processing effect are compared. It is found that laser cutting method is superior to traditional punching method in one-time processing qualification rate, sample morphology and generality. The accuracy and precision of the nitrogen content analysis results of the samples processed by laser cutting method can meet the production needs. Therefore, laser cutting method can be used to prepare samples for nitrogen content analysis in steel.更多还原
