摘　　要：通过对Q345B钢板伸长率影响因素的分析和研究,表明钢中夹杂物、异常组织及带状组织是Q345B钢板伸长率不合的主要原因。并提出了工艺改进等相关措施,改善并提高了钢板伸长率性能。The factors influencing elongation rate of Q345B steel were analyzed and studied. The results show that inclusions, abnormal structure and banded structure are the major causes of elongation rate disqualification for Q345B steel. Relevant measures to improve the process are raised, thus the elongation rate of steel plate is improved.

关 键 词：伸长率 夹杂物 带状组织
