莱钢1500mm冷轧带钢平整轧制工艺实践

介绍了莱钢1 500 mm单机架四辊平整机组的设备组成、控制系统以及平整生产模式。通过对平整延伸率自动控制系统(AEC系统)和分段张力控制系统进行分析,在工艺参数的设置、系统控制的优化、生产模式的选择等方面做到有效控制,从而提高了平整延伸率的控制精度35%,确保了平整后产品力学性能与表面质量的稳定性,产量提高了26%。

Practice of 1500 mm Cold-Rolled Strip Steel Leveling Rolling Process in Laiwu Steel

This paper describes 1 500 mm single rack equipment with four roller leveling,leveling control system and production patterns in Laiwu Steel. By the analying for automatic control system of leveling extension ratio（AEC） and segmentation of tension control system and effectively controlling in the setting of process parameters,control system optimization,production mode of selection,so as to improve the control precision of elongation,ensure the stability of mechanical properties and surface quality of the product after the leveling,the production increased by 26%,the elongation control precision increased by 35%.
