摘　　要：通过对国内某钢厂生产的SWRS82B盘条的组织、夹杂物及力学性能的研究,结果表明SWRS82B盘条的抗拉强度,屈服强度,断面收缩率,延伸率随索氏体含量的增加和索氏体片层间距的细化提高,SWRS82B盘条钢拉拔断裂的原因是钢中夹杂物存在。SWRS82B micro- structure, inclusions and mechanical properties were studied in this article. The results show tensile strength, yield strength, contraction of cross sectional area, elongation percentage are continuously improved with the increase of sorbite and thinning of sorbite lamella. Fracture of SWRS82B steel is due to the existence of inclusions in the steel.
