一、前言钢铁及铁合金中碳量之测定是一个重要的分析项目。这主要是因为,碳量对这些产品的性能,有着重要的影响,并往往以碳的含量作为判断产品品级的依据,同时正确而迅速的测定碳的含量,对冶炼过程的掌握,亦有其重大的意义。通常使用容积法,系将试样置于高温的氧气流中燃烧,生成的二氧化碳,用氢氧化钾吸收,以吸收前后体积之差,通过换算求得碳的含量,此法自一九一三年应用以来
I. Introduction The determination of carbon in steel and iron alloy is an important analysis item. This is mainly because the amount of carbon has an important influence on the performance of these products, and often takes the carbon content as the basis for judging the product quality, and at the same time determines the carbon content accurately and rapidly, as well as masters the smelting process Great significance. Volume method is usually used, the sample is placed in a high temperature oxygen stream combustion, the generated carbon dioxide, with potassium hydroxide absorption to absorb the difference between before and after the volume obtained by converting the carbon content of this method since 1913 Since the application
