Although the slitting and rolling process has effectively improved production efficiency and greatly increased output, the size of each rolled piece after slitting may not be exactly the same due to factors such as steel temperature fluctuation, groove wear, h……

In the process of slitting and rolling production, K1 top outlet failure is more common and is the main fault point that restricts slitting production. It is mainly manifested as the front end of the steel material bending sharply, thus hitting the steel pile ……

1. Adjustment methods for the length, shortness and elbow of the center line difference.2. The angle of the K5 twist outlet and the spacing between the guide rollers.3. The specific ideas and mutual relationships of the adjustment of the east, middle and west ……

It is strictly forbidden to adjust the three-line difference by lifting the east-west crossbeam:a. Due to the substantial difference in process control between three-cutting and two-cutting, the adjustment of the lifting beam will cause the size of the centerl……
