Title:
METHOD FOR MEASURING ELECTRODE LENGTH IN ELECTRIC RESISTANCE MELTING FURNACE
Document Type and Number:
WIPO Patent Application WO/2014/002192
Kind Code:
A1
Abstract:
A method for measuring the length of carbon electrodes in an electric resistance melting furnace whereby carbon electrodes suspended in the furnace are inserted into a deposited substance to be melted in the furnace and a current is passed between the electrodes to melt the substance to be melted, wherein a hole extending along the axial line to the lower end is formed in at least one carbon electrode and a microwave transmitter/receiver is mounted at the upper end of the hole, or a metal pipe that reaches the lower end of the electrode is inserted into the interior of at least one carbon electrode and a microwave transmitter/receiver is mounted at the upper end of the metal pipe, and then microwaves are transmitted and the microwaves reflected at the lower end of the hole or the metal pipe are received, whereby the length of the electrode is calculated.
