The "dynamic taper" online width adjustment technology is applied to different types of casting machines and different process requirements, meeting the following customization requirements:

1） Control the width adjustment time unchanged, whether it's adjusting 50mm or 200mm, the time required is constant, to realize the accurate control of the width adjustment process on only one billet (width adjustment billet, wedge billet).

2）Control the width adjustment amount per unit time to be constant, whether it's adjusting 50mm or 200mm, the movement amount per unit time of copper plate to be fixed, so as to achieve the consistency of copper plate movement under different width adjustment amounts.

3）According to the actual situation of the equipment, the width adjustment process can be controlled in stages to meet the requirements of matching the width adjustment operation status with the on-site equipment performance.

4）The width adjustment curve can be optimized and controlled flexibly according to the width adjustment amount and the width adjustment speed.

5）Targeted design for the judgment, control, and recovery of abnormal width adjustment events, achieving precise judgment and rapid processing, ensuring a smooth transition and the objective demand for the normal operation of subsequent production operations.
