  • Studies on the Allowance of the Chemical Analysis of Ferroalloys by J.I.S. Methods (I)

抄録

Analytical methods of ferroalloys have been applied to those of iron and steel. But there are many unsuitable points because of the difference of other alloys from iron and steel, for ferroalloys contain much Mn, Si, Cr, W, Mo, V, Ti, P, Ca (Ni, Zr, B, Co, Ta and Al) etc. as the ordinary constituents beside iron. Now, ferroallys app-proved in Japanese Industrial Standards (J.I.S.) are inspected in a different section from that for iron and steel. Often there is a differerence between a conent and its analytical value in ferroalloy, caused by its segregation or errors of analytical method. We calculated and compared the standard deviation (σ) for each analytical method. Hereunder we report those results with reference to the allowance that has been tolerated in practise.
