Abstract
Short Abstract: The paper gives an overview about refractories for a highly efficient hot metal ladle. Based on economic aspects for the lining concept, low thermal conductivity and advanced purging during deslagging are the key issues in this paper. The sulfur rich contaminated slag has to be removed thoroughly. The amount of the remaining slag and iron losses should be as low as possible. The optimal location of the plugs was determined with CFD- analysis and is presented in the paper too. Finally some safety issues are rounding up the topic. Key words: HM- ladle, lining configuration, heat losses, thermal conductivity, purging equipment, purge plugs, deslagging, CFD- simulation, steel shell temperature, condition monitoring |
