摘要
对实验室和工业生产的410S热轧钢带进行金相组织、拉伸性能和断口形貌对比分析,认为通过改变热轧轧制工艺,即降低后几道次轧制温度、增加道次变形量,促使热轧钢带再结晶,这种再结晶组织可明显提高钢带的性能,达到软化钢带的目的。工艺改进后生产的热轧钢带组织为大部分再结晶铁素体和部分沿晶界析出的颗粒状碳化物。
The metallographic structure, tension test properties and fractngraphy of 410S hot rolled strips produced in laboratory and of industrial production were analyzed and cnmpa^d. The results showed that through changing the rolling process, that is, decreasing the rolling temperature of last passes and increasing the reduction in pass for promoting the strip recrystallization, the recrystallized structure increased the properties of the strip markedly and softening the strip. The structure of the strip produced by improved process was most recrystallized ferrite and part granule carbide separated along the grain boundary.
