Melting and/or stirring of molten metals

A method of moving molten metal within a furnace, the method comprising:

• providing an apparatus including an electromagnetic mover adjacent to an inlet portion of the furnace, wherein the electromagnetic mover has a primary motion axis aligned along a direction of the maximum linear force generated by the electromagnetic mover;
• adjusting an orientation of an adjustable mounting frame to adjust a position of the electromagnetic mover from a first orientation to a second orientation;
• applying a current to the electromagnetic mover such that changes in magnetic field configuration cause movement of the molten metal within the furnace;
• wherein the furnace includes:
• the inlet portion that is at least partially defined by a front wall of the furnace that is inclined relative to a vertical axis of the furnace, a bottom wall, and a sidewall defining an opening;
• a furnace portion that is at least partially defined by the sidewall of the furnace and fluidly connected to the inlet portion via the opening;
• wherein, in the second orientation, the primary motion axis is inclined relative to a vertical axis of the furnace in two different planes;
• or wherein, in the second orientation, a longitudinal axis of the electromagnetic mover is inclined relative to the vertical axis in two different planes.
