Resource-saving operation and control of stainless steel refining in VOD and AOD process

Objective

The objective of the project is to improve the operation and control of stainless steel refining within the VOD and the AOD process with respect to the main metallurgical operations. This shall be achieved by detailed investigations with CFD based process models, and by application of dynamic models for on-line observation and control of the process. Furthermore a detailed investigation of operation parameters with emphasis on the slag behaviour shall be performed, and new VOD operation practices regarding lance injection of scale FeO and EAF slag with high chromium contents shall be developed.

Expected benefits are a reduced consumption of alloys, reducing agents, slag formers and process gases. Stainless steel production will be optimised regarding energy consumption and amount of slag to be deposited or recycled. The well-aimed control of decarburisation reaction will reduce the risk of potentially dangerous steel and slag overflow.
