Abstract

Die Erfindung ermöglicht es auf besonders wirtschaftliche Weise Stahlbänder (S) mit einer hohen Härte ihrer Oberflächenschichten und dementsprechend hoher Verschleißfestigkeit zu erzeugen, indem ein Coil (C), das aus einem einen Ausgangsgehalt an Kohlenstoff aufweisenden Stahlband (S) derart gehaspelt ist, dass seine Lagen mit Abstand zueinander angeordnet sind, bei einer oberhalb der Ac3-Temperatur liegenden Reaktionstemperatur einer Glühung unterzogen wird, bei der ein aufkohlendes Gas (RGas) durch den zwischen den einzelnen Lagen des Coils (C) vorhandenen Raum geleitet wird, bis in der Randschicht des Stahlbands (S) ein gegenüber dem Ausgangsgehalt um mindestens 0,1 Gew.-% erhöhter C-Gehalt erreicht ist.

The invention makes it possible to produce in a particularly economical manner steel strips (S) with a high hardness of their surface layers and correspondingly high wear resistance, by winding a coil (C) of a steel strip (S) containing a starting carbon content such that its Layers are arranged at a distance from one another, is subjected at a reaction temperature lying above the A c3 temperature of an annealing, in which a carburizing gas (RGas) is passed through the space between the individual layers of the coil (C) space, up to the edge layer of the steel strip (S) is achieved over the starting content by at least 0.1 wt .-% increased C content.
