摘要： 利用大型有限元分析软件,模拟计算了半固态A356铝合金的二次加热温度场·结果表明:在给定铝合金二次加热温度的前提下,线圈电流密度与加热时间成反比,与试样内、外温差大小成正比·当用总截面为40mm×130mm的宽线圈加热时,合适的线圈的电流密度为0 5×107A/m2和0 6×107A/m2,此时铝合金内外温差分别为8 6℃和9 8℃,加热时间分别为31min和21min;当用总截面为20mm×130mm的窄线圈加热时,合适的电流密度分别为0 8×107A/m2和0 85×107A/m2,此时铝合金内外温差分别为8 6℃和8 9℃,加热时间分别为33min和30min·本研究为A356合金半固态...

Abstract: The remelting temperature field of semi-solid A356 alloy was simulated using ANSYS software. The result showed that the current density of coil is inversely proportional to heating time and directly proportional to the temperature difference between specimen's inside and outside. The appropriate current density is 0.5 × 107 A/m2 and 0.6 × 107 A/m2 when the cross-sectional area of the coil used is 40 mm × 130 mm, and the temperature difference is 8.6°C and 9.8°C with heating time 31 min and 21 min, respectively. The appropriate current density is 0.80 × 107 A/m2 and 0.85 × 107 A/m2 when the cross-sectional area of the coil used is 20 mm × 130 mm, and the temperature difference is 8.7°C and 9.0°C with heating time 33 min and 30 min, respectively. The simulation provides theoretically a guidance for the industrial practice of semi-solid of A356 alloy.
