Embodiment Construction

[0011] An asynchronous rolling method for a metal plate comprises rolling with a rolling pair of rolls. When the metal plate is rolled, the upper and lower rolling rolls 1 and 2 in the rolling pair of rolls adopt different linear speeds. (It can be that the rotating speeds of the upper and lower rolling rolls are the same and the roll diameters are different, or the roll diameters of the upper and lower rolling rolls are the same and the rotating speeds are different). There is also a metal plate 3 in the figure.

Abstract

The invention discloses a metal plate asynchronous rolling method which adopts a rolling pair roller for rolling, and an upper rolling roller and a lower rolling roller of the rolling pair roller adopt different linear velocity when rolling metal plates. The invention has simple method, and rolled products have good metallurgical structure, fine and uniform crystal grains, strong intensity, favorable tightness and good quality.

Description

Technical field: [0001] The present invention relates to a metal sheet rolling method. Background technique: [0002] When the existing metal plate is rolled, upper and lower rollers with the same rotational speed and diameter are used for rolling. The rolled metal plate product has relatively large crystal grains and has defects in grain uniformity, compactness, strength and the like. Invention content: [0003] The object of the present invention is to provide a metal plate asynchronous rolling method with reasonable structure and good quality rolled products. [0004] Technical solution of the present invention is: [0005] An asynchronous rolling method for a metal plate, which includes rolling with a rolling pair of rolls, and is characterized in that: when the metal plate is rolled, the upper and lower rolling rolls in the rolling pair of rolls adopt different linear speeds. [0006] The speed of the upper and lower rolling rolls is the same, but the diameters of t...
