基于提高轧辊寿命的轧钢工艺优化措施

Optimization and Research of Rolling Process Based on Improving Roll Life

在分析热轧带肋钢筋切分轧制中轧辊存在掉肉、爆槽等多种问题的产生原因的基础上,以山东石横特钢集团有限公司棒材生产线为例,分析其解决轧辊存在的各种问题的具体措施,包括:利用多种装置以及相关系统,提升高轧辊的冷却效率;强化成品辊辊环的宽度,确保防止辊环崩裂掉块;对工艺装置平面配置进行改型,延长轧辊切分楔的寿命。

Based on the analysis of the causes of various problems such as pits and groove bursting in the roll during the slitting rolling of hot-rolled ribbed steel bars,taking the bar production line of Shandong Shiheng Special Steel Group Co.,Ltd.as an example,the specific measures to solve various problems of the roll are analyzed.Use a variety of devices and related systems to improve the cooling efficiency of high rollers.Strengthen the width of the finished roll ring to prevent the roll ring from cracking and falling.The plane configuration of the process device is modified to prolong the service life of the roll cutting wedge.
