摘　　要：从熔炼成分、成品成分、力学性能、加热温度、成材率、合格率、定尺率等几方面对济钢 HRB40 0新 级钢筋的生产技术指标进行分析 ,计算得出 C、Si、Mn、V与力学性能关系的回归方程式 ,对不同规格的钢筋设计了不同的化学成分 。The productive and technical indexes of HRB400 new grade Ⅲ steel bars produced by Jigang were analyzed based on the smelting and finished product composition, mechanical properties, heating temperature, rolling yield, qualification rate and the rate of cut to length etc The regressive equation between the mechanical properties and the content of C, Si, Mn, V was gotten by calculation To improve the stability of mechanical properties, the different chemical composition are designed for bars with various dimension

关 键 词：HRB400新I级钢筋 技术指标 化学成分 回归方程式
