Temperature changes during rolling of copper and their influence on resulting properties

Popis výsledku v původním jazyce

This paper deals with the influence of the temperature changes in the course of rolling on the mechanical properties of copper. The experiment was performed in the two-stand laboratory rolling mill TANDEM, determined for hot rolling. Two high-speed temperature scanners LANDSCAN were used for the measurement, making it possible the computer registration of surface temperature of not very large, relatively fast moving flat samples. Thanks to information obtained in this way it was possible to determine the relation between the heat removal into the work rolls and the surface temperature of the intensively formed samples made of the commercially pure copper. The temperature before the final reduction was on average 930 °C, the strain rate was changed in the range of ca 40 - 190 s-1. The changes of the strain rate and temperature of the rolling stock influenced significantly the course of the metadynamic recrystallization, which was found in the metallographic way, and ? in a lesser extent
