Packaging steel strip strip longitudinal uneven thickness adjustment

Packaging steel strip steel vertical longitudinal uneven thickness of the adjustment of the uneven thickness of strip steel is one of the main defects of rolling. Listed in the longitudinal uneven thickness of the influence of many factors, the poor quality of billet and mill adjustment accuracy is not high due to the instability of rolling process and the tension fluctuation is one of the most important two factors. Practice shows that using poor quality of longitudinal ( Uneven thickness and mechanical performance) Volume is still in manual operation of rolling mill, it is difficult to produce the vertical thickness of products. When using single machine for production, if the speed is low, For example, 0. About 5 m/S) For artificial thickness, just regular test regular, adjust the technology is simple, when the rolling speed more than zero. More than 8 m/s, it is difficult to manually thickness, need to install thickness measurement system for testing and display and adjust. In the use of tandem mill during the production, because of the high speed ( In general to 2. 5 - 5. 0m/s） , in addition to must be installed gauging system, adjust the technology is also more complex. Therefore, only the tandem mill under the longitudinal uneven thickness adjustment technology are discussed.
