A method of installing a refractory lining in a coreless or channel electric induction furnace. For installation of a refractory lining in a furnace wall, the method comprises the steps of providing a dry refractory material between a liner form placed within the furnace and a furnace wall, placing at least one variable frequency/amplitude electric vibrator in operational communication with an element selected from a structural member of the furnace, the liner form, and a vibrator rig placed within the furnace, inducing flow of the dry refractory material by operating at least one variable frequency/amplitude vibrator in a first operational mode having a high amplitude, low frequency vibration, and compacting the dry refractory material by operating at least one variable frequency/amplitude vibrator in a second operational mode having low amplitude, high frequency vibration after inducing flow of the dry refractory material. Methods of installing a refractory lining in a furnace floor and an inductor of a channel induction furnace also are described
