Novel concept disposable emf sensors for in situ measurements of solute contents of liquid metals in metal-refining processes

摘要

The novel feature of this unique disposable solute emf sensor for liquid metals, described in this paper, is in the use of a molten ionic polymer, e.g., aluminosilicate, as the sensor electrolyte. Theoretically, with this type of molten ionic electrolyte, it should be possible to measure the various solute contents in liquid metals. Calculated examples are given In this paper for the emf sensor measurements of Al, C, Ca, Cr, H, Mg, N, O, P, Si and S in liquid steel and/or hot metal. Examples are also given for the H, O, P and S measurements in liquid copper and H in liquid aluminium.
