Abstract
A current applying apparatus includes a pair of electrodes configured to contact a workpiece to apply an electric current to the workpiece, and a bus bar arranged to extend along the workpiece. At least one of the electrodes includes a moving electrode configured to move relative to the bus bar and the workpiece such that an electric current flows between the bus bar and the workpiece through the moving electrode, the moving electrode being connected to the bus bar so as to be movable relative to the bus bar, and the moving electrode being configured to contact the workpiece so as to be movable relative to the workpiece.

(canceled)
A current applying method for applying an electric current to a workpiece by contacting a pair of electrodes to the workpiece, the current applying method comprising:
- providing a bus bar to extend along the workpiece and to face the workpiece;
- providing an electrically-conductive brush on a surface of the bus bar facing toward the workpiece;
- and
- moving at least one of the electrodes relative to the bus bar and the workpiece and in sliding contact with the electrically-conductive brush such that an electric current flows between the bus bar and the workpiece through the at least one of the electrodes, with the at least one of the electrodes being connected to the bus bar and contacting the workpiece.
A direct resistance heating apparatus comprising:
- a current applying apparatus;
- and
- a power supply configured to supply electric current to the current applying apparatus,
- wherein the current applying apparatus comprises a pair of electrodes configured to contact a workpiece to apply the electric current to the workpiece, and a bus bar having a surface arranged to extend along the workpiece,
- wherein at least one of the electrodes comprises a moving electrode configured to move relative to the bus bar and the workpiece such that an electric current flows between the bus bar and the workpiece through the moving electrode, the moving electrode being connected to the bus bar so as to be movable relative to the bus bar, and the moving electrode being configured to contact the workpiece so as to be movable relative to the workpiece,
- wherein the current applying apparatus further comprises an electrically-conductive brush provided on the surface of the bus bar facing toward the workpiece, and
- wherein the moving electrode is arranged to move in sliding contact with the electrically-conductive brush.
