In order to increase the precision of the rolled steel products, the steel strip cold chain roll group adopts the structural form of four rolls.

More specifically, the steel strip cold chain roll group includes the steel strip upper roll one, the steel strip upper roll two, the steel strip lower roll one and the steel strip lower roll two, the steel strip upper roll one and the steel strip The specifications of the lower roll 1 are the same, the specifications of the upper roll 2 of the steel strip and the lower roll 2 of the steel strip are the same, and the upper roll 2 of the steel strip and the lower roll 2 of the steel strip directly roll the steel strip.

More specifically, the roll cores of the upper roll 1 of the steel strip, the roll cores of the upper roll 2 of the steel strip, the roll cores of the lower roll 2 of the steel strip, and the roll cores of the lower roll 1 of the steel strip are arranged section by section from left to right. distributed.

The beneficial effects of the utility model are: the continuous rolling device for rolling steel of the utility model has a reasonable structural design, and the rolled finished product can not only achieve the required shape, but also ensure its internal quality, and has a wide range of applications. And consumers have brought good economic benefits.
