Understanding Your Market Needs
To achieve stainless steel melting and refining in an AOD, the entire process requires extremely tight controls. These controls cover selecting the raw materials through to refining and casting. A typical EAF practice would be to melt down under a basic reducing slag. The AOD slag plays an important role, from decarburization to lowering sulphur levels and reducing expensive oxides back into the metal.
How can lime consumption and alloy recovery in the stainless steel melting (AOD process) be improved?
Solutions to Meet Your Needs
- Higher CaO content with stricter controls on impurities – such as SiO2, S and controlled LOI content – helps our customers to achieve reduced lime and dolomitic lime consumption as well as better chromium and silicon recovery. Reductions in lime and dolomitic lime consumption further help to reduce slag volumes, thus yielding significant process benefits.
- Our products meet these stringent specifications, which helps our customers to achieve the ideal levels of sulphur and recovery of alloys. Our ultra-low carbon lime further helps to avoid carbon pick-up during the refining stage.
