摘要
介绍了PC钢棒延迟断裂的特征及机理,分析了诱发PC钢棒延迟断裂的材料缺陷.为消除PC钢棒延迟断裂的材料缺陷,提出了改善PC钢棒用30MnS i盘条质量的工艺措施.
The features and mechanism of fracture of steel bar for prestressed concrete ( PC bars) are described, and the material defects which induced the delayed fracture in the PC bars are analyzed in the paper. In order to eliminate these defects, measures of improving the quality of 30MnSi rod coil are proposed.
