Real-time determination of the chemical analysis of metal baths is required due to the need to shorten process cycles and also to meet the demands that have emerged with the adoption of continuous refining techniques. Hence the effort to develop analytical instruments that are rapid and, if possible, permit the continuous determination of elements of particular interest. The objective of the investigations has been to develop electro-chemical sensors for the determination of silicon in hot metal, and manganese in liquid steel. A study has been made of the performance of both silicon and manganese cells of original CSM design. The studies were undertaken in the laboratory on Fe-Si-C(sat.) baths at 1500 C in the case of the silicon cell and on Fe-Mn baths at 1650 C for the manganese one. The silicon cell proves capable of determining the silicon content rapidly and reliably. Its development is such that it is now possible to consider building an industrial prototype. The manganese cell seems to be inadequate for determinations in liquid steel baths, owing to the chemical instability of the electrolyte adopted.
