摘　　要：介绍了(82B)预应力钢丝用钢盘条,C成分偏差对钢材性能的影响。盘条的深加工工艺是以冷拉拔为手段,其拉拔性能与钢的组织状态有密切关系。均匀的钢材组织以及较高的索氏体含量,都与C的成分控制有关。82B wire rod for prestressed wire by cold drawing process belongs to high-carbon steel, as the main materials for producing steel wire and prestressed strand of the high tensile strength and low relaxation prestressed concrete structure. The stretchability of 82 B wire was closely related to its microstructures. The chemical compositions of 82 B wire rod can meet the requirements of standard, uniform microstructure and a high sorbite percent and avoiding network cementite structure in order to meet the cold drawing process successfully and mechanical properties of 82 B wire rod.
