Description:
The Ohno continuous casting process for the Mg-based amorphous alloy is simulated using the finite element method. The influences of the temperature in the mold mouth, the cooling distance and the casting rate on the temperature field and the shape of the solid-liquid interface are investigated. It is found that when the temperature in the mold mouth increases from 800°C to 950°C, the convexity of the solid-liquid interface is gradually decreasing and the position of the interface is moving outward along the mold. When the cooling distance is extended from 45 mm to 85 mm, the profile of the solid-liquid interface has little change while its corresponding position is gradually far away from the mold mouth. When the casting rate increases from 1.33×10 −4 m·s −1 to 3.33×10 −4 m·s −1 , the solid-liquid interface is moving back and forth toward the outside and inside of the mold mouth. The optimal process parameters in the Ohno continuous castin...
