Understanding the Role Water-Cooling Plays During ...

its base. The defining character of the D.C. casting process is the extraction of heat due to this direct impingement of water on the ingot surface – typically more than 80% of the total heat is removed by this method under steady state conditions[5]. The thermal field in this semi-continuous process can be considered to develop in two distinct stages.
