Abstract

The invention belongs to the technical field of plate machining equipment, and particularly relates to an ultralarge-diameter-ratio asynchronous rolling mill and a plate rolling method. The ultralarge-diameter-ratio asynchronous rolling mill comprises a rolling mill rack, a press-down device, a balancing device, an upper roller system and an arc-shaped plate device. An arc-shaped plate and an upper roller are oppositely arranged, and the arc-shaped plate and the upper roller cooperate with each other to complete rolling of a plate strip. According to the ultralarge-diameter-ratio asynchronous rolling mill, ultralarge-reducing-ratio and different-speed rolling can be realized, a large bite angle is provided, and bite is facilitated; the external friction force borne by a rolled piece is reduced, and the plate strip forming quality is improved; and the reducing ratio and the different speed ratio can be adjusted within a wide range, and according to process conditions, the metal shear stress is improved, a twisting and rolling area is enlarged, metal deformation is promoted, rolling force is reduced, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of plate processing equipment, and in particular relates to an asynchronous rolling mill with a super large diameter ratio and a plate rolling method. Background technique [0002] A rolling mill is a machine that deforms metal materials through strong pressure to obtain the desired shape of the material. It can be used to make various profiles and blanks. In the actual production process, improving the quality of strip production, reducing production costs, and improving production efficiency are requirements for rolling mill design. Traditional rolling mills are mostly composed of two work rolls and multiple backup rolls. The rolled piece is controlled by two work rolls. The frictional force enters the rolling zone, where the two work rolls exert rolling force on the rolled piece, which makes the rolled piece plastically deformed to obtain the shape required for production. [0003] With the needs of act...
