HomeEnergy and productivity optimised EAF stainless steel making by adjusted slag foaming and chemical energy supply (EPOSS)
Metadaten zur Veröffentlichung
The main aim of the project is to increase the energy efficiency and productivity during EAF high alloyed stainless steelmaking by development of innovative slag conditioning techniques for slag foaming and adjusted use of all available energy sources. For this reason, different process variants of slag conditioning have been investigated at the electric arc furnaces of three stainless- and special steel producers. For slag foaming and improved chromium control in the slag, a slag conditioning technique based on CaC2 mix injection has been developed by ACRONI in collaboration with BFI. This aim is also addressed by an optimised slag conditioning technique based on the adjusted addition of FeSi and injection of carbon/oxygen, which was developed by Gerdau Sidenor. Further, for adjusted supply of chemical energy to the EAF, an innovative slag conditioning technique based on the injection of aluminium granules has been developed by BGH in collaboration with BFI. All new slag conditioning techniques have been developed based on operational trials and measurements at the EAF. Optimum process parameters in terms of maximum chromium recovery, minimum electric energy consumption and minimum process cost have been selected by comparison with standard operational procedure. Finally, a concept for each optimised slag conditioning process variant is proposed.
