| Abstract Scope |
Iterations of thermomechanical modeling on DC casting of high strength crack-prone alloy billets have been conducted to understand billet start-up phase thermal stress development and to optimize tooling design. Transient thermal stress development during cast start at the billet butt, billet surface and inside the billet are investigated; Connection of cracking with stress development at billet butt is presented; Effects of starting head, wiper placement and wiper placement location on the thermal stress development are also examined. The billet surface rebound temperatures and cast-in TC temperatures from the modeling agrees well with those measured in the laboratory and in the field; the casting campaigns on the AirSlip® mold package exhibit great billet quality and high pit recovery. |
