More Information
Summary:A lift plug for lifting a graphite electrode includes a main body and an insert coupled to one end of the main body, with the insert configured to mate with a graphite electrode to secure the lift plug to the graphite electrode. The lift plug also includes a lifting component coupled to the main body opposite the insert to lift the graphite electrode. The insert comprises a non-graphite material with a coefficient of thermal expansion (CTE) similar to graphite, such that the lift plug expands at a similar rate as the graphite electrode when heated so as to prevent locking at a joint between the lift plug and the graphite electrode. Un tapón de elevación para elevar un electrodo de grafito incluye un cuerpo principal y un inserto acoplado a un extremo del cuerpo principal, con el inserto configurado para acoplarse a un electrodo de grafito para asegurar el enchufe de elevación al electrodo de grafito. El tapón de elevación también incluye un componente de elevación acoplado al cuerpo principal opuesto al inserto para elevar el electrodo de grafito. El inserto comprende un material no grafitado con un coeficiente de expansión térmica (CTE) similar al del grafito, de tal manera que el tapón de elevación se expande a una velocidad similar a la del electrodo de grafito cuando se calienta, con el fin de prevenir que se bloquee en una unión entre el tapón de elevación y el electrodo de grafito.
