Abstract
EN ESTE HORNO, SE DESVIA EL ARCO VOLTAICO DEL DISPOSITIVO DE ALIMENTACION DE CORRIENTE (19) BAJO INTERACCION DEL CONDUCTO DE ALTA CORRIENTE QUE SE EXTIENDE POR DEBAJO DE LA CUBETA DEL HORNO. ESO PRODUCE UNA SOBRECARGA TERMICA EN UNA PARTE DEL REVESTIMIENTO DEL HORNO. DISPONIENDO LAS CAPAS DE REVESTIMIENTO DE MODO QUE UN PRIMER SECTOR (21), QUE SE ABRE HACIA EL DISPOSITIVO DE ALIMENTACION DE CORRIENTE (19), SEA DE UN MATERIAL CON MENOR CONDUCTIBILIDAD ESPECIFICA QUE LA CAPA DE REVESTIMIENTO DEL SEGUNDO SECTOR (22), EL ARCO VOLTAICO ACTUA DE NUEVO SIMETRICAMENTE. UNA CAPA DE REVESTIMIENTO TAN HETEROGENEA PUEDE EMPLEARSE ADEMAS PARA UNA DESVIACION DELIBERADA DEL ARCO VOLTAICO.
