Abstract
A system including a graphite electrode having a graphite body with first and second opposed ends. The electrode further includes a threaded connector positioned at one of the first or second ends, and a tag coupled to or positioned in the threaded connector, wherein the tag is configured to transmit a signal including information relating to the electrode.
Claims23
A system comprising:
- a graphite electrode including:
- a graphite body having first and second opposed ends;
- a threaded connector, in the form of a pin, or in the form of a socket defining an inner cavity, positioned at one of the first or second ends;
- and
- a tag that is coupled to the pin when the threaded connector is a pin, or that is positioned in the inner cavity of the socket when the threaded connector is a socket, wherein the tag is configured to transmit a signal including information relating to the electrode, and wherein the electrode is configured for use in an electric arc furnace.

A system comprising a graphite electrode including:
- a graphite body having first and second opposed ends;
- a threaded connector positioned at one of the first or second ends;
- a tag coupled to or positioned in the threaded connector, wherein the tag is configured to transmit a signal including information relating to the electrode;
- and
- a monitor configured to receive the transmitted information relating to the electrode, and to determine a missing electrode to be an electrode having associated information that was previously received by the monitor but for which information is not currently received.
2 more elements
A graphite electrode comprising:
- a graphite body having oppositely positioned first and second ends;
- a first threaded connector positioned one of the first or second ends, wherein the first threaded connector is a pin or a socket;
- a second threaded connector positioned at the other one of the first or second ends, wherein the second threaded connector is the other of the pin or a socket, wherein the one of the threaded connectors that is a socket is sized and configured to threadably receive the other one of the threaded connectors that is a pin therein such that multiple electrodes can be coupled together in a modular manner;
- and
- a tag attached to or positioned on a radially oriented planar end surface of the first or second threaded connector, wherein the tag is configured to emit a non-line-of-sight signal representing an electrode identifier, and wherein the electrode is configured for use in an electric arc furnace.
2 more elements
A method comprising:
- accessing a graphite electrode for use in an electric arc furnace including a graphite body having first and second opposed ends, a threaded connector positioned at one of the first or second ends, the threaded connector having a planar end surface aligned in a radial plane, and a tag coupled to the end surface of the threaded connector;
- and
- receiving a signal from the tag, the signal including information relating to the electrode.
