摘　　要：根据电磁分离铝熔体中的非金属夹杂物数值模拟结果 ,设计并制作了电磁感应线圈和分离器。感应线圈的设计参数为 :长度 2 5 0mm ,长度方向匝数为 12 5匝 ,高度 10 0mm ;高度方向的匝数为 2匝 ,宽度为 10 0mm ,宽度方向的匝数为 2匝 ,两线圈距离为 40mm。分离器内腔尺寸为 80mm× 2 0mm× 80mm ,分离通道尺寸为 37.5mm× 2 0mm× 80mm。研究了铝熔体温度、时间和线圈电流对分离铝熔体中非金属夹杂物的影响 ,结果表明 ,当铝熔体温度为 740℃ ,分离时间为 3min以上 ,线圈通入 2 0A电流时 。An inducation coil and separator were designed and manufactured according to the numerical simulation results of electromagnetic separation of inclusions from molten aluminum. The length of coil is 250 mm and the turn number is 125. The height of coil is 100 mm and the turn number is 2; the width of coil is 100 mm and the turn number is 2. The distance between two coils is 40 mm. The measurement of inner cavity of separator is 80 mm×20 mm×80 mm and the measurement of separating channel is 37.5 mm×20 mm×80 mm. The experiment of electromagnetic separation of inclusions from molten aluminum was conducted. The experiment results show that efficient separating inclusions from aluminum is gained when the molten aluminum temperature is about 740 ℃, the separating time is more than 3 min, the coil current is 20 A.[
