The laboratory experiments have been carried out to investigate the mass transfer phenomenon during electroslag remelting (ESR) with a focus of establishing a slag-metal multiphase reaction model. The multiphase reaction model based on the penetration and film theories is established to analyze the concentration changes of sulfur and alloying elements in steel along the height of ESR ingot. The results show that the concentration of sulfur in ingot at the beginning of ESR process is lower than the rest process because of the large distribution ratio of sulfur combined with excellent kinetic conditions. In the first slag-temperature-rising period, the aluminum in ingot has the increasing trend with the increase of temperature. And two ways can solve this problem: the one is starting up the ESR furnace by high temperature molten slag technology, and the another one is adding extra titania into molten slag continually in the first slag-temperature-rising period.
