摘要

A process for measuring the rate of oxidation on the surface of a metal melt wherein the oxide skin on the melt surface is removed at constant temperature and the electromagnetic radiation during the subsequent oxidation is measured with an infra-red radiation pyrometer such that the variation in intensity of the electromagnetic radiation indicates the rate of oxidation. The process can also be employed for measuring the concentration in a metal melt of the elements influencing the rate of oxidation.
