摘　　要：通过对一条热浸镀锌铝合金生产线产渣率高问题案例的分析，论证了以下事实：铁在锌铝合金熔体内的实际溶解量达到其平衡溶解度数倍，析出的铁铝合金化合物数量随着含铝量的下降显著减少，大约在低于35％铝成分时底渣全部转变为顶渣，铁铝化合物会相互碰撞聚集而长大，并吸附大量的熔体一起成为顶渣。This article demonstrates the following facts by the case analysis of high production of hot dip Zn-A1 plating residue.The actual dissolved amount of iron in the zinc-alnminium alloy melt reaches number times of its equilibrium solubility. The ferro-aluminum alloy iron compounds we get descends significantly with the decline of A1 content. When aluminum is under 35%, all the bottom slag turns into top slag. The ferro-aluminum alloy compounds grow bigger when collide and gather with each other, adsorb great amount of meh and turns into top slag by the case analysis of high production of hot dip Zn-A1 plating residue.
