To reveal the effects of magnesium on the evolution of oxide and sulphide inclusions in liquid iron,both thermodynamic calculations and deoxidization experiments were carried out.The samples extracted from the liquid iron were polished and analyzed by optical microscopy and scanning electron microscopy.The results showed that magnesium could modify oxide and sulphide inclusions simultaneously.Spherical MgO and irregular spinel inclusions were observed in the samples.The elongated MnS inclusions were replaced by small MgO·MgS or MgO·MgS·MnS complex inclusions,and the sulphides were distributed dispersively.The evolution mechanisms of inclusions were discussed comprehensively,and a proposed model for the formation of oxysulphide was set up. |
