Abstract
The invention discloses a shielding device for an intermediate frequency furnace bottom. The device is formed by the welding of two semi-circular plates, and the welding joint surface of the two semi-circular plates is shaped like a sawtooth. The device enables a conventional linear joint surface to be changed into the sawtooth-shaped joint surface, and increases the area of the joint surface, i.e., increasing the overcurrent capability of the joint surface. The device prevents the thermal deformation and a too large short-circuit current from causing cracks, and guarantees the safer and more effective operation of an intermediate frequency furnace.
