Grain refinement of extralow-carbon steels in hot strip rolling

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The effect of various operational parameters such as the finishing temperature, the final reduction, the cooling rate, the onset time for cooling after the final rolling in a hot strip rolling process on the grain refinement of hot rolled extralow carbon steel bands has been investigated. To analyze the experimental results, a metallurgical model for predicting the microstructural evolution of extralow carbon steels in hot working processes was developed. The calculated results were found to correlate relatively well to experimental ones and indicate that the effect of various operation conditions on grain refinement can be explained by considering the evolution of the dislocation density in austenite and the transformation temperature.
