Abstract
A process and apparatus for controlling the position of a cast ingot is provided so that unwanted distortions of the casting are substantially avoided. The instant process and apparatus also permit substantially uniform heat transfer about the casting periphery. A control system for maintaining the casting within a mold so that the casting outer periphery is substantially uniformly spaced from the mold inner wall comprises a casting supporting mechanism adjacent the mold exit and non-thermal position detectors.
