Continuous casting (CC) is a process of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine. It is the predominant process route in a modern steel plant which links steelmaking with hot rolling of steel. In the CC machine, the liquid steel is solidified into a semi-finished steel ...
