| Abstract Scope |
DCC mold developments aim at meeting criteria either internal or external to the castshop. To the first category belong operational robustness, mold simplicity, mold versatility in terms of alloys and water quality, that is the possibility to obtain very high recovery rates whatever the alloy hot cracking or curling tendency, in any casthouse regardless of its particular water supply. To the second category belongs the minimisation, potentially the suppression of butt sawing before rolling. Constellium has striven to suppress butt cracking during start-up and surface cracks in steady state. Also, the butt curl pattern can have significant impact on cracking affecting unsawn butts during rolling. This has led us to reconsider the choice of jets angles and start-up strategies of the commercially available technologies, and eventually to develop our own mold technology, now patented and widely deployed within Constellium. |
