Abstract

ESTA INVENCION SE REFIERE A UNA PIEZA FUNDIDA DE ACERO INOXIDABLE AUSTENITICO PRODUCIDO SOBRE UNA FUNDIDORA CONTINUA DE RODILLO DOBLE, UNA PLACA DE ACERO LAMINADO EN FRIO, Y UN METODO DE FABRICACION DE ESTOS, Y LOS OBJETIVOS SON OBTENER UNA PLANCHA DE ACERO INOXIDABLE AUSTENITICO DELGADA LIBRE DE LA APARICION DE DESBASTE DE SUPERFICIE DURANTE LA OPERACION DE MOLDEADO EN FRIO. SE PRODUCE UNA FINA PIEZA DE PRODUCCION POR UN METODO DE COLADA CONTINUA DE RODILLO DOBLE CON EL GRADO DE SEGREGACION DE NI, QUE SE DEFINE POR LA SIGUIENTE ECUACION (1), EN LA PARTE DE LA PIEZA FUNDIDA QUE ESTA CERCA DEL CENTRO DE UNA SECCION TRANSVERSAL DE ESTA REGULADO PARA NO BAJAR DE 0.9, Y LOS COMPONENTES DE LA PIEZA FUNDIDA SON REGULADOS DE MANERA QUE EL PORCENTAJE DE DELTA-FECAL DEFINIDO POR LA SIGUIENTE ECUACION (2) NO ES INFERIOR A 6 ESTANDO LA PIEZA FUNDIDA RESULTANTE SUJETA A LAMINADO EN FRIO UNA O DOS VECES PARA OBTENER UNA PLACA DE ACERO. DE ACUERDO CON ESTE METODO, LA COLADA SE HACE CON UN UNA FUERZA DE PRESION DE TAMBOR POR LONGITUD DE UNIDAD DE 3-25 KG/MM APLICADA EN LA DIRECCION ANCHA DEL TAMBOR DE REFRIGERACION SOBRE UN PUNTO DE CONTACTO. EL GRADO DE SEGREGACION DE NI = % DE CANTIDAD MEDIA DE NI, UNA PARTE SEGREGADA/ (%) DE CANTIDAD MEDIA DE NI EN UNA PIEZA FUNDIDA... (1) (5) DE DELTA FECAL = 3(CR + 1.5 SI + MO + O.5 NB) 2.8 (NI + 0.5CU + 0.5MN + 30C + 30N) MASA) ... (2).
