Zusammenfassung:	A lifting adaptor configured to lift a graphite electrode includes a main body having a threaded end to secure the lifting adaptor to threads of the graphite electrode, and a lifting component coupled to the main body opposite the threaded end to lift the graphite electrode. The threaded end of the main body may comprise a non-graphite material with a coefficient of thermal expansion (CTE) similar to Invar, within +/−0 to 1 (μm/(m K)) over a range from room temperature to 400 degrees Fahrenheit.
