Controlled Rolling - an overview | ScienceDirect Topics

In CCR, rolling is performed in two stages: (a) “roughing” rollling at high austenite temperatures (1150–1000 °C), which results in repeated SRX and refines the initial coarse austenite grain size to ∼20 μm and (b) “finishing” rolling where the steel is cooled below T nr and multipass rolling is carried out to the final thickness with temperature decreasing to ∼800–840 °C during the final …
