PCT No. PCT/DE94/01497 Sec. 371 Date Jul. 18, 1996 Sec. 102(e) Date Jul. 18, 1996 PCT Filed Dec. 6, 1994 PCT Pub. No. WO95/16336 PCT Pub. Date Jun. 15, 1995A process and a device for regulating the position of the tip of an electrode immersed in an electric furnace heated by electric arc or resistance heating. To precisely measure the position of the electrode tip and to position it in operation, a series of gas containers are introduced into the electrode in succession at certain intervals, with each gas container being given a serial number (ni). The position of the electrode tip is determined by computer from the data of the last gas container with the serial number (nj) and the current number of the melted-open gas container, determined by gas analysis, using the gas that rises in the furnace through the melting process. Control technology is then applied to the drive of the electrode bearing device.
