Fundamental Study on Casting Simulation of Environmentally Friendly Light Alloys

在不同吸气压力、不同熔体温度和不同型腔厚度条件下，用吸力试验研究了ADC12铝合金的流动长度。对ADC12铝合金和AZ91D镁合金在不同条件下的流动长度进行了数值模拟。结果表明，ADC12铝合金结晶器表面与熔体之间的热阻约为3.3mm2 K/W，AZ91D镁合金约为5.8mm2 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.
