摘　　要：通过实验优化了CS-444(HF-400)的测试过程,分别探讨了助熔剂用量、助熔剂种类及助熔剂样品的放置情况对钢铁中碳含量测试的影响。结果表明,助熔剂为钨铁混合助熔剂,组成为1.2 g钨粒+0.5 g铁,采用助熔剂与样品均匀混合的放置条件,得出的结果准确性和重复性满足要求。由此可得出结论,在相同的测试条件下,样品的燃烧反应完全,测试结果准确、经济、合理,并且可以为钢铁中相关碳含量的测试过程提供参考。The testing process of CS-444(HF-400)was optimized through experiments,and the effects of flux dosage,flux type,and flux sample placement on carbon content testing in steel were explored.The results showed that the flux was a mixture of tungsten and iron,with a composition of 1.2 g tungsten particles and 0.5 g iron.The results obtained were accurate and reproducible under the condition of uniformly mixing the flux with the sample.From this,it can be concluded that under the same testing conditions,the combustion reaction of the sample is complete,the test results are accurate,economical,and reasonable,and can provide reference for the testing process of related carbon content in steel.
