Effect of Deformation Heat on Mechanical Properties of Intensively Rolled Steel

Popis výsledku v původním jazyce

The two-stand laboratory hot rolling mill TANDEM was equipped with a pair of the high-speed temperature scanners LANDSCAN, enabling the accurate computer recording of surface temperatures of the rolling stocks. The effective system was developed, consisting in the on-line computing and displaying the maximum value of the temperature measured during one pass of the rolling stock under the measuring equipment. Thanks to such information, it was possible to quantify the effect of the deformation heat and heat removal into the working rolls on the surface temperature of the intensively hot rolled samples from mild steel St37, obtained at various rolling speeds. Due to these effects the actual finish rolling temperature was significantly different from thenominal one (i.e. 940 °C on average, before the final pass). The real finish rolling temperature was in the range 901 - 978 °C. This change had a great impact on mechanical properties of the laboratory rolled products, determined by tensi
