The Steel Composition Prediction Model for ESR Ingot of GCr15SiMn

摘要：

　　Based on the molecule and ion coexistence theory, thermodynamic equilibrium and mass conservation, a model for GCr15SiMn has been established to predict the steel composition in ESR (Electroslag Refining) ingot. Then the equilibrium contents of dissolved Mn, Si, Al, Ca and O at the interface between the metal molten film at the electrode tip and slag are calculated under different initial contents of Al in electrode and SiO2 in slag pool. The results demonstrate that increasing content of SiO2 aggravates the oxidation of Al, which will cause the increase of O content and decrease of Ca content. Under low SiO2 and high Al contents, Mn content will be higher than the initial content, while high Al and SiO2 contents will lead to Si content higher than the initial content. With increasing the initial Al content under the same slag composition, the equilibrium contents of Mn, Si, Al and Ca will increase while O will decrease.
