FORNO ELETTRICO AD ARCO A CORRENTE CONTINUA CON CONNESSIONE AL CROGIUOLO

摘要

A DC arc furnace hearth is formed by brickwork having electric conductors extending through it, the conductors at their bottoms connecting with an electrically conductive layer on which the brickwork is layed and having top ends contacted by a melt contained by the brickwork. Arcing power can be transmitted via the conductive layer and conductors to the melt.
