摘　　要：本文对喂线法与传统冲入法汽车曲轴生产工艺进行了对比,总结了喂线法在生产铁小件中的优势。与冲入法相比,喂线法具有球化剂加入量少、温降小、产生渣量小、残镁量易于控制、球化效果好、球化效果稳定、回炉料加入量大等优点。In this paper , the wire feeding method and the conventional method in production of auto-mobile crankshaft is compared , summing up that the wire feeding method has an advantage in the pro-duction of iron small part .Compared with the conventional method , the wire feeding method has the advantage , such as less nodulizer added , less temperature drop , less amount of slag produced , resid-ual magnesium content that is easy to control , good spheroidizing effect , stable spheroidization effect , more foundry returns .

关 键 词：喂线法 汽车曲轴 球化处理 残镁量 球铁小件
