The invention discloses an automatic operation system for an electric induction furnace. The automatic operation system comprises a furnace stage zone (100), a furnace front zone (200) and a furnace rear zone (300), wherein the furnace front zone (200) is provided with iron tapping rails (201) and molten iron ladle trolleys (203); the furnace front zone (200) is further divided into a post-ironmaking zone (210), a left iron tapping zone (221), a left prior-ironmaking zone (231), a right iron tapping zone (222) and a right prior-ironmaking zone (232); the post-ironmaking zone (210) is internally provided with slag dredging mechanical arms (211); the left iron tapping zone (221) and the right iron tapping zone (222) are separately provided with a flow-following material feeding device (223); the left prior-ironmaking zone (231) and the right prior-ironmaking zone (232) are separately provided with a weighing material feeding device (233); and the furnace rear zone (300) is provided with rail-type automatic material feeding devices and rail-type mechanical arm devices. By adopting the automatic operation system, automatic operation of the electric induction furnace is realized; labor intensity of personnel is lowered; safety is enhanced; production efficiency is improved; and smoke and dust generated by the electric furnace during iron tapping and after iron tapping be treated.
