钢铁中碳量的摄谱法测定,由于技术上的困难,不便在生产上使用。本文用高频火花和中等色散的棱镜摄谱仪,选用了镁对电极,有效地提高了碳谱线强度,作出了碳素钢及合金铸铁中碳的分析方法,可以分析低至0.04%的碳。一、引言碳是钢铁的主要成分。碳含量的高低显著地影响钢铁的性能。由此可见,钢铁中碳的测定对于冶金、机制造等部门具有重要意义。钢铁中碳的化学测定方法很多。基本的原则是在测定碳量时,首先将试样中的碳在高温(1150～1350℃)通氧燃烧生成二氧化碳
Determination of carbon steel in the spectrometry, due to technical difficulties, inconvenience in the production. In this paper, high-frequency spark and moderate dispersion of prism spectrograph, the selection of magnesium counter electrode, effectively increasing the intensity of carbon lines, made of carbon steel and alloy cast iron carbon analysis can be as low as 0.04% carbon. First, the introduction of carbon is the main component of steel. The level of carbon content significantly affects the performance of steel. Thus, the determination of carbon in steel for metallurgy, machine manufacturing and other departments of great significance. There are many ways to determine the carbon in steel. The basic principle is to determine the amount of carbon, the first sample of carbon at high temperature (1150 ~ 1350 ℃) oxygen combustion to generate carbon dioxide
