WebMay 10, 2004 · The direct chill (DC) casting process for aluminum alloys is shown schematically in Figure 1(b). In contrast to the con-tinuous casting process for steel, DC casting is only semicon-tinuous; as the strand is withdrawn vertically for a short length ( 10 m) until the process must be stopped and WebThe direct chill (DC) casting process is used for 68% of the aluminum ingots produced in the U.S. Ingot scrap from stress cracks and butt deformation account for a 5% loss in production. The basic process of DC casting is straightforward. However, the interaction of process variables is too complex to analyze by intuition or practical experience. fnaf games you can play

Web1.1.2 Direct-chill Casting Process-a brief introduction The modern Direct-Chill (DC) process was invented in 1936-38 nearly simultaneously in Germany (W Roth, VAW) and the USA (WT. Ennor, ALCOA). Their process was based on prior methods (for copper and aluminum alloy casting) proposed by B. Zunkel (1935) and S. Junghans (1933). WebMar 7, 2016 · Due to the common application of passive iron chill-molds in casting processes it may be assumed that an active cooling system will have no negative effect on the crystalline structure of the cast material.
