The Reason for Storing Rolling Data While Unloaded Operation in Rolling-line
Rolling is an important processing method for metal materials which has attracted the attention of many experts in the industry. The rolling process is a complex production process which involves many parameters and is inherently uncertain. If the instability of the rolling process is not mastered in time, it will bring great economic losses to the enterprise. In order to improve the accuracy of the rolling process, many rolling plants have adopted the strategy of collecting and storing rolling data while unloaded operation in the rolling line so that they can study, analyze and promptly detect and adjust various conditions of the rolling process.
The rolling-line unloaded operation mainly relies on the work of the individual rollers, while controlling the speed and pressure to ensure that a certain rolling force is formed. The roller inverter drives the spindle and arranges the appropriate speed according to the program set in advance, making the roller couple periodically moves along the laying head guide rail, so as to obtain the longitudinal rolling force. The roller linear guide system absorbs displacement and serves as a power transmission shaft. Moreover, the rolling line is driven by the roller pair to achieve the output of the desired rolling force.
Unloaded operation of the rolling line is the main way to obtain rolling data. During this operation, the pressure, speed, force and etc rolling data are collected and stored through the line control and rolling process monitoring system to facilitate the study and analysis of the rolling process and improve the accuracy of the rolling process.
In addition, the cylinder displacement of the rolling line can be automatically adjusted according to the one-way compensation of the rolling data during unloaded operation, so as to improve the rolling force and quality of the product. During the rolling process, some parameters need to change with the change of the material being rolled, at this time, the compression parameters can be adjusted through the stored rolling data of the unloaded operation in time.
In view of the above, storing rolling data while unloaded operation in the rolling line is of great significance for improving the accuracy and quality of the rolling process. With the help of this data, it can not only reflect the changes of the rolling process in real time, but also improve the accuracy of the process procedure and reduce economic losses. The stored rolling data can also provide important reference and guidance for the rolling process design and control which can ensure the best operation effect of the production process and ensure the produce qualified products.
