Function of Uncoiling in Feeding

The function of uncoiling in feeding is to enable the steel strip to rotate smoothly under the action of the uncoiler and to feed the steel strip steadily into the next process. The steel strip for spiral seam double-sided submerged arc welded pipes is relatively thick, wide, and heavy, resulting in a slower uncoiling speed. Vertical and horizontal adjustments of the coil on the uncoiling stand can be achieved through hydraulic control. The uncoiler for the spiral seam double-sided submerged arc welded pipe mill consists of two side wall stands, which are made of welded wear-resistant steel plates. Each side wall stand is equipped with two hydraulic cylinders for horizontal and vertical adjustment of the coil, respectively.
