随着科学技术的发展,超低碳或超低硫的材料日益增多,正确地分析超低硫超低碳无疑对生产这些材料是至关重要的。然而金属材料中的超低碳和超低硫的分析历来是比较困难的问题,人们虽然做过大量工作,但多数方法仍不够理想,自高频燃烧-红外检测方法问世以来,从它在常量碳硫测定中应用的情况来看,该法灵敏度和精度比较高,似可用于超低碳和超低硫的分析,值得探讨。为此我们进行了以下工作。试验证明,LECO GS-244红外碳硫测定仪测定超低碳硫(pom)试样,效果甚佳,精度可达±2
With the development of science and technology, ultra-low carbon or ultra-low sulfur materials are increasing day by day. Therefore, correctly analyzing ultra-low sulfur ultra-low carbon is undoubtedly crucial for the production of these materials. However, the analysis of ultra-low carbon and ultra-low sulfur in metal materials has always been a difficult problem. Although many people have done a lot of work, most methods are still not ideal. Since the advent of high-frequency combustion-infrared detection, Carbon and sulfur determination of the application of the situation, the sensitivity and accuracy of the method is relatively high, it may be used for ultra-low carbon and ultra-low sulfur analysis, it is worth discussing. To this end we have done the following work. Test proved that, LECO GS-244 infrared carbon sulfur detector for the determination of ultra-low carbon sulfur (pom) sample, the effect is very good, the accuracy of ± 2
