RAPID DETERMINATION OF OXYGEN IN THE MOLTEN STEEL.

Abstract

A method was developed which is improved from the Herty Process and capable of determining the oxygen content in the molten steel in 15 minutes. Some minutes are required to separate carbides in case where the specimen contains more than 1% C and 1% Cr. But still it presumably meets the purpose because of the capability of determination within 25 minutes. Besides, various preparatory tests were conducted during the course of the present experiment and, consequently, it was recognized that the error happened in the analysis lies within the order of the experimental errors.
