Adopted by asynchronous rolling is a kind of unequal rolling speed when the composite rolling, working roll surface linear speed up and down, in order to reduce rolling force. Asynchronous rolling is a new rolling technology has many advantages. Asynchronous rolling can greatly reduce the rolling force, light weight of equipment, low power consumption, the mill small deformation, high precision products; reduced roll wear and intermediate annealing, reduce production costs; rolling pass, productivity high; mill rolling thickness. The two-roll mill is generally refers to the rolling mill rolls are horizontally arranged, the upper and lower two rollers are arranged in the same vertical plane, it’s simple structure, a wide range of uses. The subject of this study is host of small composite test mill design, completing the design of the host of the two-roll rolling mill and the corresponding measurement control sensor installation, and rolling mill part of the functional and structural aspects of improvement and innovation, to enable them to be efficient, stable accurate production of qualified products.
