工艺参数对热轧双相钢力学性能的影响

EFFECT OF TECHNOLOGICAL PARAMETERS ON MECHANICALPROPERTIES OF HOTROLLED DUALPHASE STEEL

在正交试验的基础上，采用方差分析的方法研究了四个工艺参数（终轧温度θｆ，终轧变形量εｆ，淬火温度θｑ，以及轧后缓冷时间ｔｎ）对单张热轧双相钢（０．０７％Ｃ－１．６９％Ｍｎ－０．９３％Ｓｉ）力学性能的影响，据此，提出了较优的生产工艺参数。

Based on the results of orthogonal experiment,the effect of four technological parameters (final rolling temperature θf,degree of final reduction εf,quenching temperature θq,time of slow cooling after rolling tn) on mechanical properties of hotrolled steel single of dualphase(chemical composition:007 %C169 %Mn093 %Si)sheet were investigated and optimum technological parameters were proposed
