Thickness control of hot-rolled aluminum alloy

1. During the production process of hot-rolled aluminum alloy it is necessary to ensure normal progress to prevent the breakage of the strip due to surface cracks.

2. Ensure that the products produced meet the requirements of the next process. The requirements of the subsequent process include that the size must meet the requirements. The size refers to the thickness width length or coil diameter.

In addition, the version must meet the requirements. The version refers to the convexity, wedge rate, and wave.

3. The surface quality meets the requirements and the performance meets the requirements. The performance refers to the longitudinal, transverse and high directions.

The thickness accuracy of aluminum sheet and aluminum strip is an important indicator in the production process of hot-rolled aluminum alloy. The thickness and deviation of aluminum sheet and aluminum strip are mainly achieved through the automatic thickness control system.

The automatic thickness control system uses the basic equation, the bounce equation and the roller equation.

Because there are many factors that affect the bounce of the gate and the shape of the roller, such as the process parameters, the gate parameters, and the chemical composition changes of the rolled piece, these can all affect.

The changes in process parameters and gate parameters will affect the front and rear tension compensation, acceleration compensation, and tail compensation.

The thickness and deviation of aluminum sheets and aluminum strips, the control means and technologies, especially the process model adapted to its equipment configuration, are very important, as they will affect the accuracy of pre-setting and regulation, thereby affecting the stability and uniformity of the thickness of the aluminum strips and aluminum coils over the entire length.
