Abstract
METODO PARA MEJORAR LA RECUPERACION Y UNIFORMIDAD DE DISTRIBUCION DE INGREDIENTES ALEANTES EN UN ACERO.CONSISTE EN: A) EMPLEAR UN TAMAÑO DE GRANALLA DE 0,5 A 2,0 MM, COMPUESTO DE INGREDIENTES DE ALEACION DE BISMUTO, ALEACION PLOMO-BISMUTO, ALEACION BISMUTO-TELURO Y OTROS; Y B) ALIMENTAR LA GRANALLA, A TRAVES DE UNA BOQUILLA (26) POR GRAVEDAD O CON PISTOLA DE INYECCION, A UNA CORRIENTE DE COLADA (24) DE ACERO QUE FLUYE DESDE UNA CUCHARA DE COLADA (23) HASTA UNA LINGOTERA (25).
