Bending roll

The shape of strip was controlled by CVC roll,bending roll,roll shifting and mathematical model after 1422mm hot strip mill was reformed in Meishan Iron and Steel Corp.

介绍了梅山钢铁股份有限公司热轧板厂在对1422mm热连轧机的技术改造中,通过采用CVC辊型、弯辊和轧辊轴向横移等板形控制技术,以及板形设定模型来控制板形。

It is found that the pressure of bending roll is not adequate,and the hydraulic actuation device responds slowly.

通过对薄板厂 1#冷轧机厚度控制系统工作原理进行详细分析后发现 ,整个系统存在弯辊压力不足 ,液压执行 机构响应缓慢 ,工作辊高速运转时容易产生跳动以及轧机在不同速度段存在共振等现象 ,这些因素是影响 1#轧机不能有效产出厚度≤ 0 。

In view of the above,combining the actual production situation of the 1 422 rolling strip line of Meisteel,analyzes the effect factors of the hot-roll strip profile controlling,including the original roller allocating,the hot profile controlling for the roller,the matching application for the shifting roll and the bending roll,the rolling program editing and the fieldoperating adjusting.

据此,结合梅钢1 422 mm轧线的实际生产情况,对热轧带钢凸度控制的影响因素进行了分析,并分别从原始辊型配置,轧辊热凸度的控制,机组窜、弯辊的配合应用,轧制计划的编排及现场操作的调整等方面提出了相关见解。

A synthesis set model for roll bending force was built,which was taken the good shape of strip as the object and the relative margin uniform of every roll bending force as the constraint condition.

针对双机架冷轧机组的生产工艺特点,以及传统弯辊控制技术的不足,综合协调控制1#机架工作辊、1#机架中间辊、2#机架工作辊和2#机架中间辊4部分弯辊力,以成品板形质量最佳为优化目标函数,同时将各个部分弯辊力的相对余量均匀作为约束条件,确定出弯辊力综合设定模型,该模型可提高弯辊对板形的控制能力,延长弯辊缸的使用寿命。

model, by which the relation among HCW mill roll bending force Fw, working roll axial move S and strip profile has been set up.

应用分割模型影响函数法计算辊系的变形，建立了ＨＣＷ轧机弯辊力ＦＷ、工作辊轴向移动Ｓ与板带材横断面形状的关系的数学模型，结合武钢热轧厂Ｆ４～Ｆ７精轧机改造的实际情况，表明理论分析与生产实践基本一致，证明ＨＣＷ轧机能够自由轧制、提高产品质量和成材率，是现有四辊轧机改造的理想方案之一。
