建立模拟铸造过程中铝液泄漏的模型以预防爆炸,包括瞬态溜槽流动,孔口出流和扩散.将仿真数据和理论计算结果进行比较,验证该模型的适应性和准确性.即使改变混合炉中铝液高度和出口半径,铝液在浇注过程也不会发生泄漏.溜槽中的铝液以波浪状的形式向前移动并引起泄漏,泄漏铝液在地面上的扩散呈长条状,铝液泄漏量和扩散面积随着混合炉中铝液高度的增大而增大.
Numerical simulation of liquid aluminum leakage in casting process
A model was built to simulate liquid aluminum leakage during the casting process, including transient trough flow, orifice outflow, and spread, to prevent the explosion. A comparison between the simulation data and the theoretical calculation results verifies that the model has remarkable adaptability and high accuracy. Although the height of liquid aluminum in the mixing furnace and outlet radius are changed, the molten aluminum will not leak during the casting process. The aluminum in the trough moves forward in a wave-like motion and causes a leakage. The spread of the leaked aluminum resembles a long strip on the ground. The leakage amount and spread area of liquid aluminum increase with increasing the height of liquid aluminum in the mixing furnace.
