摘要
依据热轧卷取工艺特点,对钢卷的内部应力分布进行了分析,并考虑卷取温度对材料发生相变的影响,指出相变体积变化对钢卷卷形的影响,分析了钢卷径向卷形出现不良问题的机理。结合实际生产65Mn出现的扁卷缺陷,对卷取温度进行了调整优化,解决了扁卷问题。
According to the characteristics of the coiling process for hot rolling,the internal stress distribution of steel coils was analyzed.And considering the effect of coiling temperatures on the phase transformation which occurred in steel materials,the effect of the volumetric change caused by phase transformation on the shape of steel coils was pointed out.Then the mechanism of the bad shape of steel coils in radial direction was analyzed.Combined with the flatted-coiled defects occurred in actual production of 65Mn steel,the coiling temperature was adjusted and optimized,and the problem on the flatted-coiled defect was solved.
