摘　　要：针对Φ22 mm螺纹钢(HRB335)屈服强度不合格的问题,对随机抽取的288炉钢的化学成分、负差及屈服强度进行了统计分析。利用数学回归方法得出了碳、锰与屈服强度的关系,通过化学成分调整,解决了屈服强度不合格的问题。To the problem of yield strength of Φ 22 mm deformed steel bar（HRB335） being unqualified,the statistics analysis is done for 288 randomly extracted heats of steel in their chemical composition,negative deviation and yield strength.With mathematical regression the relation between carbon,manganese and yield strength is got,and the problem got solved with adjusting chemical composition.

关 键 词：螺纹钢 屈服强度 线性回归 负差
