Application of laser measuring instrument in installation and maintenance of rolling mill

The main equipment of modern large-scale rolling mill is the rolling mill. The laser outer diameter measuring instrument determines the output and quality of products. With the progress and development of science and technology, the rolling mill has achieved continuous operation, and its product quality requires high precision. For example, the 2030mm Cold Rolling five stand continuous rolling mill is a continuous endless rolling mill with a speed of 1900m per minute. It is equipped with plate shape and CVC control technology, and the thickness tolerance of the rolled cold rolled sheet is required to be 5-10 μ M U.M or less. Accordingly, higher requirements are put forward for the installation accuracy of the rolling mill. The rolling mill equipment with high precision for continuous rolling is installed on the soft soil foundation. Although measures have been taken in the foundation design, the foundation is still in a state of unstable settlement, even large deflection, which directly affects the installation accuracy and progress of the rolling mill equipment. In order to install the rolling mill with high quality and high speed, the traditional installation process is reformed and a new installation process and corresponding new installation technology are established.
