Abstract
SE PRESENTA UN PROCEDIMIENTO DE AFINADO AL VACIO DE ACERO FUNDIDO, UTILIZANDO UN FLUJO DE REFINADO, CONSISTENTE EN BORBOTEAR UN GAS COMBUSTIBLE Y UN GAS DE OXIGENO, HACIA EL ORIFICIO DE SALIDA DE UNA LANZA DE DISPOSITIVO DE AFINADO, SITUADA POR ENCIMA DEL BAÑO DE ACERO, A FIN DE CREAR UNA LLAMA DE COMBUSTION POR DEBAJO DE DICHA LANZA, Y, ADEMAS, SUMINISTRAR EL FLUJO DE AFINADO HACIA EL INTERIOR DE DICHA LANZA, UTILIZANDO UN GAS DE OXIGENO COMO GAS TRANSPORTADOR, HACIENDOLO PASAR A CONTINUACION A TRAVES DE LA LLAMA DE COMBUSTION, DE FORMA QUE DICHO FLUJO DE FUSION TERMICA, LLEGA A LA SUPERFICIE DEL ACERO FUNDIDO. EN ESTE CASO, LA VALOCIDAD DE ALIMENTACION DEL FLUJO DE AFINADO, Y LA VELOCIDAD DE FLUJO CIRCULANTE DEL ACERO FUNDIDO, DURANTE EL PROCESO DE AFINADO, SE REGULAN DE FORMA QUE MANTENGAN UNA RELACION PREDETERMINADA ENTRE SI, LOGRANDOSE UN BAJO REQUERIMIENTO DE UNIDADES DE FLUJO, PARA UNA CAMPAÑA DEL RECIPIENTE DE VACIO.
