摘要

Method and device for measuring a chemical composition of a liquid metal suitable for coating a steel strip. The present invention describes a method for measuring a chemical composition of a liquid metal (1) suitable for coating a steel strip for which the liquid metal is formed continuously in a first cavity (2), and the composition of said liquid metal is measured on a direct measurement surface (6) thereof, for which a specimen of the liquid metal reaching the measurement surface is heated (at 7) to a chosen temperature so as to isolate principally iron-based impurities from said measurement surface. Several embodiments of devices suitable for implementing said method according to the invention are also presented.
