Abstract In order to study the influence of various components of slag system on the oxidizable elements Al and Ti in the alloy during the electroslag remelting process of the Inconel718 superalloy，based on the five-component slag CaF2-CaO-Al2O3-MgO-TiO2，through the molecular and ion coexistence theory，a thermodynamic model for the oxidation of Al and Ti in the slag-gold interface during the electroslag remelting process of Inconel718 superalloy was established according to the equilibrium reaction and the material conservation of each component in the slag-metal interface. By analyzing the model and performing slag-metal balance verification experiments on the model results，the validity of the model is verified. The results showed that the change of CaF2 and MgO percent in the slag has little effect on the Al and Ti elements in the alloy. The Al2O3 in the slag has the effect of burning Ti to increase Al，the TiO2 has the effect of burning Al to increase Ti，and the CaO can inhibit the burning of Al element. The slag ratio that can reduce the burning of Al and Ti during the electroslag remelting of the Inconel718 superalloy is：20%-25%CaO，4%-6%TiO2，1%-4%MgO，50%-60%CaF2，and 15%-20%Al2O3.
