摘　　要：为了了解锌铝合金凝固过程温度的传递状况,建立了普通金属型铸造实验条件下的大直径(准114 mm)锌铝合金的几何物理模型。利用有限元方法对锌铝合金锭的凝固传热过程进行了模拟,得到了铸锭凝固过程温度分布及演变过程。这能为提高锌铝合金的铸造质量提供依据。To understand the status of transmitting temperature of zinc-aluminum alloy in solidification process, a geometrical physical model of the zinc-aluminum alloy with the large diameter （φ114mm） under the common metal mold casting experimental conditions was established. The heat transfer process of the zinc-aluminum alloy ingot in solidification was simulated by using the finite element method. The temperature distribution and evolution process of the cast ingot in solidification were gotten. This can provide a basis for improving the casting quality of the zinc-aluminum alloy.
