摘　　要：用自行研制的高效排杂熔剂进行净化处理 ,探讨了其对提高高强电工铝杆塑性和导电性等的作用 .结果表明 :经高效排杂熔剂净化处理后 ,铝杆中的夹杂物和气孔含量显著降低 ,除杂率和气孔降低率分别达73.5 %和 92 .1% ,配合晶粒细化处理后 ,与常规处理相比 ,明显提高了铝杆的性能 ,尤其在强度提高的同时 ,伸长率仍得到显著提高 (幅度达 6 2 .7% ) ,电阻率降低幅度也达 0 .93% .The effect of purification with high efficient flux removing inclusion on the plasticity and conductivity of high electrical aluminum rod was studied in this paper.The experimental results show that the rate of removing inclusions and the extent of lowering porosity amount to about 73.5% and 92.1%,respectivity after purification with high efficient flux removing inclusion.When the refining treatment is carried out after high efficent purification,the mechanic properties of aluminum rod are further improv...
