Cold rolling reel is an indispensable and core piece of equipment supporting the full operation of the cold rolling strip steel production line in the modern steel processing industry. It is widely matched with various key production processes and units, including pickling and rolling on-line units, reversing rolling mills, continuous annealing lines, and strip steel finishing lines, which cover the whole process of cold rolling strip steel pretreatment, rolling, heat treatment and post-processing. As a key auxiliary equipment connecting each production link, it undertakes the crucial material transmission and winding tasks throughout the cold rolling production process.
The core working principle of the cold rolling reel is to complete the automatic uncoiling and coiling operations of raw strip steel under normal temperature production conditions. In the initial stage of production, it stably uncoils the original steel coil to provide continuous strip steel materials for subsequent rolling and processing procedures. After the strip steel completes rolling, annealing, finishing and other process treatments, the reel will neatly coil the processed strip steel into finished steel coils for convenient storage, transportation and secondary processing.
In addition to basic coiling and uncoiling functions, precise tension control technology is applied throughout its entire working process. This accurate tension regulation can effectively avoid common production defects such as strip steel wrinkling, stretching, deviation and surface scratches caused by unstable stress. It ensures the flatness, thickness uniformity and surface quality of the finished cold rolling strip steel, and greatly improves the stability, continuity and finished product qualification rate of the entire cold rolling production line.
