Abstract
LA INVENCION SE REFIERE A UN METODO PARA PROPORCIONAR EL GAS PRINCIPAL DE FORMA EFECTIVA AL INTERIOR DE UN BAÑO DE METAL FUNDIDO, QUE ES ESPECIALMENTE UTIL EN UN HORNO DE ARCO ELECTRICO. DICHO METODO EMPLEA LA COMBUSTION DE OXIGENO SECUNDARIO CON COMBUSTIBLE, PARA FORMAR UNA ENVUELTA DE LLAMA ALREDEDOR DE UNA CORRIENTE DE GAS PRINCIPAL QUE PROTEGE EL GAS DEL ARRASTRE DE GASES AMBIENTALES, AL PASAR A TRAVES DE LA ZONA SUPERIOR DEL HORNO. ESTO PERMITE QUE EL GAS CONSERVE EN UN GRADO CONSIDERABLE, SU FUERZA ORIGINAL TRAS SU INYECCION EN LA ZONA SUPERIOR Y, POR TANTO, QUE PUEDA SER INYECTADO A UNA DISTANCIA SEGURA RESPECTO A LA SUPERFICIE DEL METAL FUNDIDO, LOGRANDO SIN EMBARGO UNA PENETRACION PRACTICAMENTE COMPLETA EN EL SENO DEL METAL FUNDIDO.
