Title:
METHOD FOR PERIODICALLY ELONGATING AN ELECTRODE FOR AN ELECTRIC ARC FURNACE
Document Type and Number:
WIPO Patent Application WO/2002/080624
Kind Code:
A1
Abstract:
The inventive method consists in screwing a pre-prepared new cathode and a nipple to an electrode column. Said nipple has a longitudinal through hole in which a metallic rod, made for example of aluminium or copper is arranged. Said rod is melted at a working temperature of the electrode column and fills cavities in the joint between the electrodes and the nipple, filling partially an additional cavity in the electrode body. A gas mixture is removed from the additional cavity, devoid of liquid metal, through holes in the electrode body, to the working space of the furnace. The inventive electrode for carrying out said method is provided with additional socket plates disposed along the axis thereof in the bottom of a threaded socket. The cavities have different diameters and depths. One of the additional socket plates is connected to the external surface of the electrode through the holes.
