摘要
针对热轧钢带经常出现扁卷现象,以碳素结构钢50Mn为代表的中高碳钢热轧钢带为研究对象,通过在不同温度下进行卷取,测试卷取后在卷筒上停留与否的扁卷率和硬度,研究得出此类优质碳素结构钢的热轧钢带需在600℃时进行卷取,并且卷取后需在卷取机卷筒上停留30 s^60 s时间,从而避免扁卷现象。
For the coil collapse phenomenon of hot rolled strip,carbon structural steel 50 Mn was as the study object of medium-carbon and high-carbon hot rolled strip. The coil collapse proportion of needing or not needing stay at mandrel and hardness were tested at coiling different temperatures. The study showed that the hot rolled strip of this kind of carbon structural steel needed to be coiled at 600 ℃,and to stay at mandrel for 30 s ~ 60 s avoiding the coil collapse phenomenon.
