主　　题：molten iron prereduced ilmenite wetting interfacial permeability contact angle carbon reduction 

摘      要：An interfacial study between molten iron and the prereduced ilmenite with carbon was conducted at different melting temperatures by the sessile droplet *** wetting characteristics between molten iron and the prereduced ilmenites with carbon were investigated by measuring contact angle of the droplet of molten iron on the prereduced ilmenite *** images of the interface were also examined by the optical microscope and SEM equipped with *** volume of molten iron increased with the melting temperature increasing when titania or high-content titania slag was used as the *** contact angle decreased with the melting temperature increasing and it was independent on time at constant *** contact angle was positively correlated with the reduction degree of the ilmenite,but the work of adhesion was negatively correlated with *** smelting temperature was beneficial to the separation of iron and Ti *** permeability of molten iron into the prereduced ilmenite with carbon was more obvious with reduction degree increasing owing to the high porosity of prereduced ilmenite.
