摘要
CrMnNSi钢中氮含量一般在0.20%～0.30%之间,用的化学方法分析具有制样烦琐、操作复杂、分析时间长、误差大的缺点,通过对SQM1型脉冲加热气相色谱仪分析方法的改进,可以对钢铁中常量氮进行分析,使分析准确,分析时间缩短.
It is with the shortcomings of being inconvenient to make samples, complicated to operate, too long to take the time and large error to analyze with the chemical method the nitrogen content in CrMnNSi steel, which is normally between 0.20 to 0.30 percent. With the improved method of SQM1 pulse plus heat gas chromatography the analysis is more accurate and with less time.
