一种热轧卷取张力的控制方法
摘要：
本发明涉及一种热轧卷取张力的控制方法，所述控制方法包括卷取机头部速度控制阶段、卷取机中部张力控制阶段和卷取机尾部张力控制阶段。所述张力控制方法，主要针对薄规格高温热轧带钢尾部在辊道上的起套问题，通过一种新的卷取机尾部张力转换方法，提高带钢尾部在辊道上运行的稳定性，减少由此产生的卷形不良和边部缺陷。
摘要（英）：

The invention relates to a control method of hot rolling coiling tension. The control method comprises head speed control step of a recoiling machine, middle tension control step of the recoiling machine, and tail tension control step of the recoiling machine. The tension control method mainly aims to solve the problem that the tail of thin hot rolled strip steel is easily to be crimped on a roller bed. According to the invention, a new tail tension transfer approach of the recoiling machine is adopted, thereby improving the operation stability of the tail of the strip steel on the roller bed, and reducing the bad coiling and edge fault.
