In order to produce steel in varying qualities, molten metal treatment requires precise process control, a high level of flexibility, and especially the correct supply of process gases. Depending on the desired material grade, single or combined methods, e.g. oxygen blowing and bottom stirring with argon or nitrogen are possible. Thereby, highly resistant or predefined stainless steels can be generated.
From molten steel to high quality stainless steel – Process overview
When using this argon oxygen decarburisation treatment for producing austenite stainless steel, oxygen is initially introduced into the molten metal from the top. Subsequently, nitrogen and argon are added which reduces the oxygen partial pressure. The state of the molten metal is decisive for determining which process gases need to be adapted. Argon is either introduced into the converter from the side or from the bottom. This ensures improved decarburisation and desulphurisation, thus making the process even more efficient.
