Abstract
A method and a device measure a chemical composition of a liquid metal suitable for coating a steel strip. The method measures a chemical composition of a liquid metal suitable for coating a steel strip for which the liquid metal is formed continuously in a first cavity, and the composition of the liquid metal is measured on a direct measurement surface thereof, for which a specimen of the liquid metal reaching the measurement surface is heated to a chosen temperature so as to isolate principally iron-based impurities from the measurement surface. Several embodiments of devices suitable for implementing the method are also presented.
