Determination of the optimum deoxidant addition in steelmaking process and the investigation of an alternative deoxidant material

Abstract

It is known that the oxygen in the liquid steel causes problems in the process and quality of steel. Nowadays, the addition of aluminum to molten metal is the most common application for deoxidation of liquid steel. In this study, the optimum aluminum addition levels have been determined and an alternative material that can be used as a deoxidant has been evaluated. The optimum addition amount and the optimum alternative deoxidant were determined by optical emission spectrometry, active oxygen measurement in liquid steel, microstructure investigations, and destructive/nondestructive testing methods.
