高合金钢光谱分析准确度改进试验

在我国钢铁厂中,高合金钢的光谱分析受到准确度的限制,没有普遍展开。通过对两种有代表性的高合金钢,即P18高速钢及Я1不锈钢的试验,证明用摄谱方法采取种种改进以后,高合金钢的分析约可达到最小的百分均方误差1％左右。文中对某些工厂的先进经验曾加以介绍。对于高合金钢的准确度问题曾予讨论。

IMPROVEMENT OF ACCURACY IN THE SPECTRO-CHEMICAL ANALYSIS OF HIGH ALLOY STEELS

wideThe application of spectro-chemical analysis to high alloy steel in our steel works has been limited by the accuracy of their methods. Through the investigation upon two typical high alloy steels, ‘P18' high speed steel and ‘Я1' stainless steel, it is proved that the minimum standard deviation that can Le reached by the photographic method of epectro-chemical analysis of such high alloy steels after adopting many improvements in each step of the analysis is about 1%. Many valuable experiences from our steel factories are introduced in this paper, and the problems concerning accuracy of the spectro-chemical analysis of high alloy steels are discussed.
