热轧来料及冷轧工艺对连轧机出口板形的影响

以某冷连轧机组的生产实践、质量攻关和科研成果为基础,探讨通过热轧温度制度改善热轧来料性能的可行性,控制目标曲线对机架间及轧机出口板形的影响,优化CVC设定提高机组板形的调控能力;并阐述合理分配机架负荷改善轧机出口板形的依据及技术措施.

Effect of Incoming Hot Rolled Slab and Cold Rolling Technology on Mill Exit Strip Shape

Based on the four year production practice, technical difficulty of product quality overcoming results and scientific research achievements for a certain cold rolling tandem mill, plans have been discussed to improve the property of incoming hot rolled slab through hot rolling temperature schedule change, to control the effect of objective curve on strip shape at the exit of each stand, and to increase the strip shape control capability through CVC roll setting optimization. The reasons and technical measures have also been fully discussed for improving mill exit strip shape by reasonable rolling load assignment for each stand.
