Modeling on the Cast Start during Steel Continuous Casting Process
Abstract
Serious detects, such as surface longitudinal cracking, inner impurities, are frequently found in the slab of the cast start during continuous casting process. during this stage, molten steel is continuously filled inlo the mold cavity with surrounding mold walls and dummy bar head at the bottom. at this cast start period, the unstable fluid flow-related phenomena, including the fluctuation of molten steel, the interaction between steel phase and air phase, are the main source of quality problems and manufacture accidents. Steel products from this stage is often downgraded or rejected in order to optimize the casting process and reduce the cost by increasing the yield, relevant investigations were performed in the current study. a two-dimensional multiphase model was developed for the continuous casting process, and Volume of fluid (VOF) multiphase method was applied to track the interface between the molten steel and the air.
