Fundamental Study on Casting Simulation of Environmentally Friendly Light Alloys

通过吸力试验，研究了铝合金ADC12在不同吸力压力、金属液温度和空腔厚度条件下的流动长度。通过数值模拟研究了铝合金ADC12和镁合金AZ91D在不同条件下的流动长度。结果表明，铝合金ADC12和镁合金AZ91D的模具表面与金属液热阻适宜值分别为3.3 mm2 K/W和5.8 mm2 K/W。

The fluidity length of aluminum alloy ADC12 was investigated experimentally by using suction tests under various suction pressure, molten metal temperature and cavity thickness conditions. Numerical simulations were also conducted under various conditions to investigate the fluidity length of aluminum alloy ADC12 and magnesium alloy AZ91D. Comparisons between experimental and numerical results revealed that the suitable value of the thermal resistance between the mold surface and the molten metal is about 3.3 mm2 K/W for aluminum alloy ADC12, and 5.8 mm2 K/W for magnesium alloy AZ91D.
