Objective
Currently many Vacuum Circulation plants for the production of ultra-low carbon steel grades are equipped with an oxygen top lance. The additional oxygen supply is used, to reduce the decarburisation time, to reduce the energy losses in the vessel and to improve the long-term plant operation by decreased skull formation. The project objective is to improve the oxygen lance operation with respect to productivity, production costs, energy consumption and steel cleanliness. For on-line process control of the main lance operation parameters, model-based set-point calculations will be developed. Therefore existing process models for decarburisation and steel temperature will be extended to the metallurgical effects of lance oxygen input.
