摘　　要：对唐钢 1 0 2 2冷镦钢进行了金相组织、力学性能、化学成分等试验分析 ,找出了 1 0 2 2钢开裂的主要原因是By analysing the micro-structure,mechanical properties,chemical composition and the level of impurities of cold-upsetting steel made in TangShang iron and steel company,we have found that the reasons of cracks on the surface of the terminal cold-upsetting steel were because the pure degree was low and the content of si was high.

关 键 词：冷镦钢 镦头开裂 显微组织 夹杂物 金相组织
