Abstract

1. Disposición perfeccionada para el bloqueo de hornos eléctricos de acero, en los que las zonas de pared de los mismos se recubren con un relleno de ladrillos y con un revestimiento de desgaste de piedras de magnesia y/o dolomita con contenido de carbono y se aplica una masa corriente de solera sobre una capa de seguridad en la zona del fondo y sobre las partes inferiores del revestimiento de desgaste y se coloca una capa de masa de inyección sobre el revestimiento en la zona de gran desgaste, y en su caso, sobre zonas parciales de la masa de solera, caracterizada porque comprende la adición de una masa compuesta de 100 partes del peso de magnesia 0,5 a 5,0 partes del peso de óxido de cromo verde 0,05 a 3,0 partes de peso de hormigón 0,5 a 3, 0 partes del peso de alcalimetafosfato o alcalipolifosfato 0,2 a 1,5 partes del peso de alcalibisulfato 8 a 10 partes del peso de agua aplicada mediante inyección o untura sobre las superficies recientes frias en las zonas previstas procediéndose seguidamente a su solidficación mediante la puesta en funcionamiento inmediata subsiguiente del horno eléctrico.
