ABSTRACT:
Disclosed is an apparatus for drying and calcinating coated welding electrodes with the use of induction heating, which comprises a sectionalized slot induction heater provided with a vertically arranged slot and a plurality of electroconductive bus-bars. Each bus-bar has a different vertical width but is supplied an electric current of the same magnitude. The electrodes are conveyed through the slot induction heater using a chain conveyer carrying magnetic holders for holding magnetically the electrodes. Adjacent to the terminal areas of the chain conveyor are disposed an arrangement for loading the untreated electrodes into the above conveyor and an arrangement for unloading therefrom the thermally treated electrodes. The loading arrangement is provided with a receiving machanism allowing the welding electrodes to be arranged in parallel with a preassigned spacing and the bare terminal end of each of the electrodes to be supplied directly to the above magnetic holders, and provided further with a first orientating transporter adjacent to the outlet area of the receiving mechanism and has its carrying run arranged in a descending helical line for transferring the electrodes to a vertical position. The unloading arrangement is provided with a second orientating transporter adjacent to the outlet area of the chain conveyer and has its carrying run arranged in an ascending helical line for withdrawing the electrodes from a vertical position, and provided further with a mechanism for removing the electrodes from the magnetic holders of the chain conveyer.
