Abstract
A continuous casting device having multi-stage convergence control is disclosed. Cooling surfaces of the continuous casting device can be articulated in stages, providing individual convergence control to longitudinally spaced-apart regions of the casting cavity. In a proximal region, during which the molten metal exhibits solidification shrinkage, a first convergence profile can be used to optimally account for the solidification shrinkage. In a subsequent distal region, a second convergence profile can be used, such as to provide optimal control of exit temperature of the continuously cast article. Multi-stage convergence control can be achieved through individually articulatable cooling pads or other supports positioned opposite the cooling surfaces from the casting cavity to displace the cooling surfaces and thereby adjust the convergence profile of the casting cavity. Actuation of the individually articulatable cooling pads can effect different convergence profiles along the length of the continuous casting device.
