Abstract

Procedimiento de colada de bandas delgadas de espesor inferior a 10 mm de acero inoxidable ferrítico directamente a partir de metal líquido entre dos cilindros enfriados en rotación de ejes horizontales paralelos, caracterizado porque: dicho acero inoxidable ferrítico contiene (en porcentajes ponderales) de 11 a 18 % de cromo, menos de 1 % de manganeso, menos de 1 % de silicio, menos de 2, 5 % de molibdeno; dicho acero inoxidable ferrítico tiene unos contenidos de carbono y nitrógeno cuya suma de los contenidos no sobrepasa de 0, 05 %; dicho acero inoxidable ferrítico contiene por lo menos uno de los elementos estabilizantes titanio, niobio, circonio, aluminio, y la suma de sus contenidos está comprendida entre 0, 05 y 1 %; los otros elementos presentes son hierro y unas impurezas habituales que resultan de la elaboración; el índice yp de dicho acero inoxidable ferrítico es superior o igual a 30 %, con: yp = 420 C % + 470 N % + 23 Ni % + 9 Cu % + 7 Mn % - 11, 5 Cr % - 11, 5 Si % 12 Mo % - 23 V % - 47 Nb % - 49 Ti % - 52 Al % + 189 y porque después de la colada se efectúa un bobinado de la banda delgada a una temperatura inferior a 600°C.
