| 摘 要： | 在连铸连轧生产线采用铁素体轧制技术制备微碳钢热轧薄板,并对所制备薄板的组织、性能及织构进行分析。结果表明：铁素体轧制微碳钢热轧薄板的组织为完全再结晶铁素体,平均晶粒尺寸50 m左右。相对于常规奥氏体轧制,铁素体轧制薄板的屈服强度和抗拉强度分别下降了21%和6%,延伸率略有下降。热轧薄板的塑性应变比值为0.4,明显低于常规奥氏体轧制。薄板中存在较强的{001}织构是导致值较低的主要原因。

| Abstract: | Micro-carbon steel strip is produced by ferrite rolling on Flexible Thin Slab Rolling Production Line.The microstructure,mechanical properties and texture of the strip are studied.The results showed that the microstructure of the strip is characterized by full recrystallized ferrite,with a grain size of about 50 m.Compared with the strip produced by conventional austenite rolling,the yield strength and tensile strength of the ferrite rolled strip is lower by 21% and 6%,respectively.Also,the elongation decreases slightly.The average-value is 0.4,which is significantly lower than that of the strips produced by conventional austenite rolling.The strong {001} recrystallization texture of micro-carbon steel strip explains-value. |
