摘要
在正交设计的基础上,通过控轧控冷实验研究了锰含量、终轧温度和卷取温度对低碳钢力学性能的影响,通过统计技术对测得的力学性能数据进行了方差分析.结果表明,锰是影响实验钢强度和塑性指标的显著因素,而卷取温度对屈服强度的影响为显著.当锰质量分数为1.22%时,通过调整终轧温度和卷取温度可以使普通低碳钢的屈服强度超过400 MPa,综合性能良好.
Based on orthogonal experiment, the effects of Mn content, finish rolling temperature （FRT） and coiling temperature （CT） on mechanical properties of low-carbon steel were investigated by TMCP （thermo-mechanical control processing）, and the mechanical properties were examined by variance analysis. The results showed that Mn content affects obviously the strength and plasticity, while CT affects significantly the yield strength which can exceed 400 MPa with other mechanical properties also improved well by readjusting FRT and CT if the Mn content in tested steel is 1.22 % as mass fraction.
