Abstract

An analysis of the parameters of multi-stage controlled strip cooling during the process of rolling of 5.5 mm-diameter C70D high-carbon steel wire rod has been made in this publication. Investigations included also the analysis of the flow rate of the cooling medium and its pressure in the devices for accelerated and controlled cooling of the strip directly in the rolling line, as well as in the STELMOR line. The investigations carried out within the study have determined the cooling capacity of the accelerated strip cooling devices for specific (preset) cooling conditions. The scope of the investigations also encompassed the analysis of the effect of the employed cooling conditions on the temperature distribution and on the properties and microstructure of the steel studied. Moreover, physical modeling of the currently applicable technology of rolling the investigated steel grade was also performed.

Kurzfassung

Für den vorliegenden Beitrag wurde eine Analyse der Parameter während der multistationären kontrollierten Bandstreifenabkühlung während des Walzens eines 5,5 mm dicken kohlenstoffreichen C70D Walzdrahtes durchgeführt. Die Untersuchungen schlossen auch die Analyse der Durchflussgeschwindigkeit und des Druckes des Kühlmediums in den Anlagen für eine beschleunigte und kontrollierte Kühlung der Bandstreifen direkt in der Walzstraße sowie in der STELMOR-Linie ein. Die Untersuchungen der Studie führten dazu, dass die Kühlkapazität der Anlagen für die beschleunigte Abkühlung für die (vorbestimmten) Abkühlungsbedingungen festgelegt werden konnten. Außerdem wurden auch die angewandten Kühlbedingungen auf die Temperaturverteilung sowie die Eigenschaften und die Mikrostruktur des untersuchten Stahles analysiert. Darüber hinaus wurde auch ein physikalisches Modell der derzeitig anwendbaren Technik für das Walzen des untersuchten Stahltyps durchgeführt.
