Abstract

APARATO MEJORADO PARA GRAFITAR POR EFECTO JOULE PIEZAS ALARGADAS DE CARBON AMORFO. UN HORNO DE GRAFITACION MOVIL PARA GRAFITAR VARIAS COLUMNAS DE ELECTRODOS AL MISMO TIEMPO EN DOS TANQUES DISPUESTOS EN RELACION DE LADO CON LADO, TENIENDO DICHO HORNO UNA CONSTRUCCION DE CAJA METALICA Y UN RECUBRIMIENTO DE LADRILLOS REFRACTARIOS DISPUESTOS A LA VISTA SOBRE DICHA CONSTRUCCION DE CAJA Y QUE AUTO-COMPENSA LA EXPANSION TERMICA Y EL EMPUJE EJERCIDO DESDE EL EXTERIOR SOBRE CADA UNA DE LAS COLUMNAS DE ELECTRODODS A GRAFITAR, ESTANDO PROVISTO ADEMAS DICHO HORNO CON PANTALLAS QUE PROTEGEN CONTRA EL CALOR A LA ESTRUCTURA Y A LAS RUEDAS, CON UN SISTEMA DE ENFRIAMIENTO POR CIRCULACION DE AGUA PARA ENFRIAR LOS ELECTRODOS DE BARRAS COLECTORAS, DURANTE EL MOVIMIENTO DEL HORNO DESPUES DEL PROCESO DE GRAFITACION.
