Abstract

Der Erfindung betrifft eine Schiene mit hoher Verschließ­ festigkeit im Schienenkopf und hoher Bruchsicherheit im Schienenfuß. Kennzeichen der Erfindung ist, daß sie nach dem Walzen und einer anschließenden Wärmebehandlung im Kopf ein feinperlitisches Gefüge und im Fuß ein martensi­ tisches Vergütungsgefüge aufweist. Die Erfindung umfaßt ferner bevorzugte Wärmebehandlungsverfahren für die Schiene. The invention relates to a rail with a high closure strength in the rail head and high break resistance in the Rail foot. Characteristic of the invention is that it rolling and subsequent heat treatment a fine pearlitic structure in the head and a martensi in the foot table has remuneration structure. The invention encompasses further preferred heat treatment processes for the Rail.
