ABSTRACT

A mathematical model for a unidirectionally solidified ingot cooled with a multi-set water-cooling system was established with ProCAST software. Temperature and heat flux fields in a 45 t ingot during solidification under the influences of a traditional water-cooled stool and an improved one were predicted by using this model. The results of temperature distribution and heat flux field show that the proposed chassis cooling system can improve the vertical temperature gradient. Uniform columnar grains from the top to the bottom of the ingot were revealed by the modeling results indicating that improved mechanical properties of the cast product could be achieved.
