针对传统的热轧带钢平整线一阶张力控制工艺存在带钢表面划伤和卷形错层的问题,开发了一种新型二阶张力控制工艺,其通过配置开卷机、矫直机、平整机、张力装置和卷取机等设备作为张力分段点,实施二阶递增张力控制策略,提高了带钢表面质量,以及板形和卷形质量。
In order to solve the problem that the traditional first-order tension control technology of the hot-rolled strip flattening line has the problem of the strip surface scratching and the rolling staggered layer, a new type of second-order tension control technology is developed. By uncoiler, straightener, The whole machine, tension device and coiler and other equipment as tension sub-point, the implementation of second-order incremental tension control strategy to improve the strip surface quality, as well as the plate and roll quality.
