To provide an electric melting furnace controller capable of providing stable operation not affected by experience of an operator with respect to an electric melting furnace having a main electrode, a furnace bottom electrode, and a starting electrode.

In the electric melting furnace controller 1, sending or exchange of control data is carried out between an electrode vertical movement control panel 23 moving electrode positions of the main electrode and the starting electrode in the furnace, and an electric power unit applying a voltage between each electrode, and operation control with respect to each electrode is carried out. It is provided with a starting control part 6 carrying out automatic operation control of the main electrode and the starting electrode in response to a state of an object to be melted at starting, and controlling the furnace until steady operation of melting the object to be melted is achieved just by automatic operation control of the main electrode, and an electrode vertical movement control part 7 carrying out movement control of the electrode position of the main electrode with respect to the electrode vertical movement control panel 23 so as to control voltages applied to the main electrode and the starting electrode at a set value during the steady operation.
