摘要
提出了一种ZG25Mn_(18)Cr_(4)光谱分析控制样品的研制方法。用火花放电原子发射光谱法和统计学方法,并结合硫印、低倍、超声检测方法,评估ZG25Mn_(18)Cr_(4)铸件浇道的均匀性。选用均匀性好、化学成分有代表性的浇道为原料,用国家标准化学分析方法或认定的分析方法定值后,制成控制样品。多年生产测试应用,结果满意。
A method for development of ZG25Mn_(18)Cr_(4) control sample for spark discharge atomic emission spectrometry(SDAES)was proposed.SDAES and statistics,combined with sulphur print,macroscopic examination and ultrasonic testing were used to evaluate the homogeneity of running channel of ZG25Mn_(18)Cr_(4) steel castings.A running channel in good homogeneity and representative of the chemical composition was used to form the control sample for SDAES after certified values with the national standard methods for chemical analysis or other certified methods.The control sample has been applied to SDAES in the ladle analysis for years with satisfactory results.
