Selecci\u00f3n de acero para herramientas para rodillos de laminaci\u00f3n<\/h1>\n\n\n\n

Los rodillos de laminaci\u00f3n operan bajo una fuerte tensi\u00f3n de compresi\u00f3n, contacto superficial repetido y, en el laminado en caliente, ciclos t\u00e9rmicos intensos. Por lo tanto, la selecci\u00f3n del acero para herramientas debe comenzar con el modo de falla predominante en servicio, en lugar de basarse \u00fanicamente en la dureza.<\/p>\n\n\n\n

En la pr\u00e1ctica, los rodillos de laminaci\u00f3n suelen fallar de tres maneras. La primera es el desgaste abrasivo, donde la fricci\u00f3n continua y la cascarilla eliminan gradualmente el material superficial. La segunda es la fatiga por contacto de rodadura, donde la tensi\u00f3n subsuperficial repetida provoca la iniciaci\u00f3n de grietas y el desprendimiento de material. La tercera es el agrietamiento t\u00e9rmico en la laminaci\u00f3n en caliente, donde el calentamiento y enfriamiento repetidos producen fisuras por calor y aceleran el da\u00f1o superficial. El grado adecuado depende de cu\u00e1l de estos mecanismos controla la vida \u00fatil del rodillo.<\/p>\n\n\n\n

Para aplicaciones de laminaci\u00f3n en fr\u00edo, la resistencia al desgaste y la resistencia a la fatiga por contacto son los criterios de selecci\u00f3n principales. Una alta dureza mejora la resistencia a la abrasi\u00f3n y la deformaci\u00f3n superficial, pero una fragilidad excesiva aumenta el riesgo de agrietamiento y descamaci\u00f3n bajo carga c\u00edclica. Para aplicaciones de laminaci\u00f3n en caliente, la prioridad pasa a ser la dureza en caliente y la resistencia a la fatiga t\u00e9rmica. Un material que se comporta bien en condiciones de desgaste en fr\u00edo puede fallar r\u00e1pidamente si no soporta choques t\u00e9rmicos repetidos.<\/p>\n\n\n\n

L\u00f3gica de selecci\u00f3n para rodillos de laminaci\u00f3n<\/h2>\n\n\n\n

Si el principal problema es el desgaste superficial constante en el laminado en fr\u00edo, un acero para trabajo en fr\u00edo de alta resistencia al desgaste suele ser la opci\u00f3n correcta.<\/p>\n\n\n\n

Si el rodillo falla por astillamiento, agrietamiento o desprendimiento, la tenacidad se vuelve m\u00e1s importante que la m\u00e1xima resistencia a la abrasi\u00f3n.<\/p>\n\n\n\n

Si la aplicaci\u00f3n implica ciclos repetidos de calentamiento y enfriamiento, se requiere un acero para trabajo en caliente con resistencia al agrietamiento por calor.<\/p>\n\n\n\n

Esta es la base pr\u00e1ctica para la selecci\u00f3n de grado.<\/p>\n\n\n\n

Aceros para herramientas recomendados<\/h2>\n\n\n\n
\n

Acero para herramientas AISI D2 | 1.2379 | SKD11<\/h3>\n\n\n\n

El acero D2 es id\u00f3neo para laminaci\u00f3n en fr\u00edo, donde la resistencia al desgaste es fundamental. Su composici\u00f3n con alto contenido de carbono y cromo le confiere una gran resistencia a la abrasi\u00f3n y una buena resistencia a la deformaci\u00f3n pl\u00e1stica bajo cargas de compresi\u00f3n elevadas. Esto lo convierte en una opci\u00f3n pr\u00e1ctica para rodillos de laminaci\u00f3n en fr\u00edo que deben mantener la integridad de su superficie durante largos periodos de producci\u00f3n.<\/p>\n\n\n\n

La dureza de trabajo t\u00edpica es de 58 a 62 HRC.<\/p>\n\n\n\n

No se recomienda el acero D2 cuando la falla por laminaci\u00f3n se debe principalmente al agrietamiento o al desprendimiento de material. Su alto contenido de carburo mejora la resistencia al desgaste, pero reduce la tenacidad en comparaci\u00f3n con los aceros de trabajo en fr\u00edo de menor aleaci\u00f3n.<\/p>\n\n\n\n

\n

Acero para herramientas AISI A2 | 1.2363 | SKD12<\/h3>\n\n\n\n

El acero A2 es la mejor opci\u00f3n cuando el rodillo requiere una combinaci\u00f3n m\u00e1s equilibrada de resistencia al desgaste y tenacidad. En comparaci\u00f3n con el acero D2, ofrece menor resistencia a la abrasi\u00f3n, pero mayor resistencia a la propagaci\u00f3n de grietas bajo tensi\u00f3n c\u00edclica.<\/p>\n\n\n\n

La dureza de trabajo t\u00edpica tambi\u00e9n es de 58 a 62 HRC.<\/p>\n\n\n\n

El acero A2 es m\u00e1s adecuado que el D2 para aplicaciones de laminaci\u00f3n en fr\u00edo donde la rotura de rodillos, el da\u00f1o en los bordes o la fatiga del material ya son un problema. No es la primera opci\u00f3n cuando la m\u00e1xima resistencia al desgaste es la \u00fanica prioridad.<\/p>\n\n\n\n

\n

AISI M4<\/h3>\n\n\n\n

El acero M4 se utiliza en aplicaciones de laminaci\u00f3n en fr\u00edo muy exigentes, donde se requieren alta dureza, alta resistencia a la compresi\u00f3n y gran resistencia al desgaste. Es especialmente adecuado para condiciones de trabajo exigentes en los rodillos, como las del laminador Sendzimir.<\/p>\n\n\n\n

La dureza de trabajo t\u00edpica es de 62 a 65 HRC.<\/p>\n\n\n\n

Cuando se produce mediante metalurgia de polvos, el M4 logra una distribuci\u00f3n de carburos m\u00e1s fina y uniforme, lo que mejora su tenacidad en comparaci\u00f3n con los m\u00e9todos convencionales de producci\u00f3n de acero r\u00e1pido. Esto lo hace m\u00e1s eficaz para resistir tanto el desgaste abrasivo como la fatiga por contacto de rodadura en condiciones severas de laminaci\u00f3n en fr\u00edo.<\/p>\n<\/div>\n\n\n\n

Resumen pr\u00e1ctico de selecci\u00f3n de materiales<\/h2>\n\n\n\n

Para rodillos de laminaci\u00f3n en fr\u00edo expuestos principalmente al desgaste abrasivo, el D2 es una opci\u00f3n pr\u00e1ctica y centrada en la resistencia al desgaste.<\/p>\n\n\n\n

Para rodillos de laminaci\u00f3n en fr\u00edo con mayor riesgo de agrietamiento o descamaci\u00f3n, el acero A2 proporciona un equilibrio m\u00e1s seguro y orientado a la tenacidad.<\/p>\n\n\n\n

Para aplicaciones de laminaci\u00f3n en fr\u00edo muy exigentes, con altas demandas de dureza, resistencia a la compresi\u00f3n y resistencia a la fatiga, el M4 es la opci\u00f3n m\u00e1s resistente.<\/p>\n\n\n\n

Para rodillos de laminaci\u00f3n en caliente sometidos a ciclos t\u00e9rmicos repetidos, la direcci\u00f3n H26 es la adecuada, ya que el problema de selecci\u00f3n ya no se limita al desgaste, sino que tambi\u00e9n incluye la resistencia al agrietamiento por calor y el mantenimiento de la resistencia a temperaturas elevadas.<\/p>\n\n\n\n

Conclusi\u00f3n<\/h2>\n\n\n\n

La selecci\u00f3n del acero para herramientas en los rodillos de laminaci\u00f3n debe basarse en el patr\u00f3n de falla observado durante su uso. Los aceros D2, A2 y M4 son adecuados para la laminaci\u00f3n en fr\u00edo, pero priorizan la resistencia al desgaste y la tenacidad de forma diferente. El acero H26 se rige por una l\u00f3gica de selecci\u00f3n distinta, donde la dureza en caliente y la resistencia a la fatiga t\u00e9rmica determinan su rendimiento. El grado adecuado es el que mejor se ajusta al mecanismo de da\u00f1o predominante, no simplemente el de mayor dureza.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
