LIDERAZGO LEADERSHIP El carril es un producto siderúrgico de gran complejidad, tanto por los aspectos de diseño técnico y proceso de fabricación, como por el constante aumento del nivel de exigencia en las condiciones de servicio. El carril debe ser capaz de dar respuesta satisfactoria al incremento de las cargas arrastradas, los aumentos de velocidad, la mayor frecuencia de paso, la comodidad (en las líneas de pasajeros) y, muy especialmente, a la seguridad vial. Hoy en día sólo un pequeño grupo de fabricantes de carril une a su gran experiencia una dinámica de mejora continua en sus instalaciones...

CARRIL DE CARGAS PESADAS 1. CARRIL MICROALEADO PROPIEDADES TECNOLОGICAS Los resultados poco satisfactorios de los carriles de acero al carbono-manganeso en los puntos de las líneas férreas donde las condiciones de servicio son extremadamente severas (curvas de pequeño radio, cargas por eje superiores a 30 toneladas, etc.), han impulsado el desarrollo de nuevos carriles con superiores características mecánicas. Históricamente, se utilizaron con este propósito aceros aleados, con valores de dureza Brinell superiores a 320 HBW y resistencia a la tracción del orden de 1.100 MPa. Estas propiedades...

HEAVY HAUL RAILS 1. MICROALLOYED RAILS TECHNOLOGICAL PROPERTIES The poor performance results of carbon-manganese steel rails at the points in rail tracks characterised by extremely harsh service conditions –low radius curves, axle loads of over 30 tonnes, etc.– have led to the development of new rails with improved mechanical properties. Traditionally, alloyed steels, with Brinell hardness values of over 320 HBW and a tensile strength of around 1,100 MPa, were used for this purpose. These properties were achieved by using high levels of manganese, chromium and molybdenum, alloys that reduce the...
