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 line differences.
4. The use of K3 and K4 hole types, mainly focusing on the influence of the fullness and size of the K3 and K4 material types coming out of the three lines on the finished products, laying the foundation for further optimization of the K3 and K4 hole types.
5. Pay attention to the fullness and width of the K2 hole type rolling groove: the influence on the quality of the finished products; the influence on the 3# looper.
6. Pay attention to the use of the gap between the K3 outlet slitting wheels, the service life of the slitting wheels, and the use of the slitting knives.
7. Pay attention to the influence of the change of the 7# material type on the process control of each pass of the finishing rolling and the influence on the quality of the finished products.
8. Pay attention to the wear of the 8# and 9# machine hole types, and summarize the amount of steel over the 8# and 9# machine hole types.
9. Pay attention to the delay of the 3# looper to ensure that the cut steel can be smoothly bitten into the K2 rolling mill.
10. Pay attention to the corresponding relationship between the head and tail size of the finished product, material shape control, and the looper situation.
11. Pay attention to the current change of the motor, the dynamic speed drop of the motor, and the impact of the motor compensation time on the looper and the quality of the finished product.
