Answers to Questions Regarding the Deviation Control Device in Rolling Mill Units

Recently, many customers have been inquiring about issues related to the deviation of mill units and seeking advice on how to control it. First, I would like to talk about the factors that may cause the deviation of steel strips. Factors such as equipment installation accuracy, steel strip shape, and the wear of transmission rollers can all lead to the deviation of steel strips. Deviation is easily prone to affect the quality of the rolled coil and damage the equipment. Therefore, controlling the deviation of mill units is of significant importance.

Next, let's briefly introduce four measures to reduce deviation:

During equipment installation, it is crucial to ensure that the installation workers pay attention to installation accuracy, strictly follow the parameter positions for installation, and avoid rollers colliding during the installation process, which could damage the surface shape.

Choose the correct and suitable arrangement of mill units and process parameters. The speed of the mill units and the tension of each unit have a significant impact on the deviation of the steel strip. Faster mill unit speeds lead to more severe deviation, while higher unit tensions can improve deviation.

Adjust the shape of the steel strip appropriately to enhance the quality of the rolled coil.

Install a deviation control device in the mill unit to narrow the range of steel strip deviation and control it within an appropriate range. In continuous operation, this control device plays a crucial role.

Finally, a reminder to all customers, the control of mill unit deviation is crucial in the rolling process, determining your efficiency and production output. Therefore, it is essential to pay attention to it during the production process.
