Abstract
Disclosed is an electric heating device capable of uniformly applying an electric current to a workpiece without causing abrasion of electrodes. An electric heating device includes a pair of electrodes for applying an electric current to a workpiece, and a pair of clamps for fixing the workpiece. The electrode extends along the surface of the workpiece in a direction perpendicular to an electric current direction while maintaining a constant length in the electric current direction, and sandwiches the workpiece therein. The clamp is arranged in the vicinity of the electrode, and sandwiches a part of the workpiece other than a part to be heated therein. A pressure at which the clamp sandwiches the workpiece therein is higher than a pressure at which the electrode sandwiches the workpiece therein.
Claims6
An electric heating device for applying an electric current to a plate-like workpiece having two flat surfaces parallel to each other to heat the workpiece, comprising:
- a pair of electrodes for applying the electric current to the workpiece, which is arranged at a predetermined interval in an electric current direction in which the electric current is applied to the workpiece;
- and
- a pair of clamps for fixing the workpiece,
- wherein each of the electrodes extends along the two surfaces of the workpiece in a direction perpendicular to the electric current direction while maintaining a constant length in the electric current direction, and sandwiches the workpiece therein so as to press the two surfaces of the workpiece,
- wherein each of the clamps is arranged in a vicinity of each of the electrodes, and sandwiches a part of the workpiece other than a part to be heated therein so as to press the two surfaces of the workpiece, and
- wherein a pressure at which each of the clamps sandwiches the workpiece therein is higher than a pressure at which each of the electrodes sandwiches the workpiece therein.
