摘　　要：风电铁素体球铁的主要成分有Fe、C和Si,其碳含量测定的准确性很重要。本研究基于检测技术,通过生产现场实际检测,重点对比了直读光谱仪法、碳硅仪法和碳硫仪法三种碳含量检测方法的检测结果,分析了直读光谱仪法和碳硅仪法现场检测碳含量的局限性和其中产生差异的原因;分析了试样白口化程度对检测结果的影响。验证了生产现场的经验判断,提出了注意事项和综合应用的解决办法。The main components of ferritic wind power castings are Fe,C,and Si,the determination of its carbon content is very important.This article is based on the detection principle and the actual testing results.We focus on comparing the differences between three carbon content detection methods,spectrometer,carbon-silicon meter and carbon-sulfur meter.We study the limitations of spectrometer and carbon-silicon meter methods,further we analysis the possible reasons for the differences.We also analyze the impact of sample chilling on the detection results,verify the empirical judgment on the production site,propose precautions and comprehensive application solutions.
