Abstract
The continuous casting process is superior to conventional casting in several ways, including more uniform production, energy savings, higher productivity and foremost the ability to cast to a form that is directly rolled on finishing mills. Characteristics of the process, including solidification time of minutes versus hours for ingot casting and high stress development in the solidifying shell, are discussed. A generalized approach to modelling heat transfer, solidification and stress distribution in continuous casting were developed. Illustrated models of this application include a simulation of the casting process with a view towards predicting temperature ranges, stress distributions and the effects of the operating parameters. The ratio of maximum applied stress to yield stress is used as a basis to predict the location of the bending rollers and the radius of the curved portion. This stress ratio provides design engineers with a tool for predicting effective parameters on a continuous casting machine for new installation design.
