一、前言 ZR-22BS-42型20辊冷轧机,是可逆式左右卷取带张力轧制的应力轧机。为轧制出优质硅钢片,使带材断面均匀、不出现折纹,必须对卷取机张力进行严格控制;在启动、制动、加速、减速及稳态轧制等过程中,均应保持张力的恒定。若张力有波动,不仅对带材本身的变形有直接影响,还间接影响轧辊的变形,辊形变动又直接影响板厚控制。张力波动、带材本身弹性变形波动,
I. Introduction ZR-22BS-42-type 20-roll cold rolling mill is reversible about the winding tension with tension rolling mill. For the rolling of high-quality silicon steel sheet, the strip cross-section uniform, no crease, the tension must be strictly controlled coiler; in the start, braking, acceleration, deceleration and steady-state rolling process should be maintained Stable tension. If the tension has fluctuations, not only has a direct impact on the deformation of the strip itself, but also indirectly affect the roll deformation, roll changes and directly affect the thickness control. Tension fluctuations, the strip itself elastic deformation fluctuations,
