为研究固定磁场对离心铸造合金组织的影响,制造了一种装有永久磁铁的离心铸造机,成功制备出了铝硅合金半固态试样。结果表明,在离心机上加装永久磁铁能够影响离心铸造合金的凝固组织,永久磁铁的位置和数量不同时,对合金凝固组织的影响也不同,磁铁与冷型距离越近,数量越多对凝固组织的影响越明显。 In order to study the influence of the fixed magnetic field on the centrifugal casting alloy structure, a centrifugal casting machine equipped with a permanent magnet was manufactured and a semi-solid sample of Al-Si alloy was successfully prepared. The results show that the permanent magnet on the centrifuge can influence the solidification structure of the centrifugal casting alloy. When the position and number of the permanent magnet are different, the influence on the solidified structure of the alloy is also different. The closer the distance between the magnet and the cold, The more obvious the impact of the organization.
