| Abstract: |
| The rolling production of metal thin strips, especially the production of stainless steel and copper thin strips with high yield strength, due to the limitation of the minimum rolling thickness, multi roll mills with small working roll diameter are mostly used, and the 20 roll mill is the most common. Aiming at the problem that the actual tension of some 20 high rolling mills with long service time and low assembly accuracy has a large deviation from the set tension and is not accurate enough, this paper first designs the tension calibration device of the low precision 20 high rolling mill. Secondly, the calibration principle of the tension calibration device designed in this paper is described. Then, according to the calibration principle and specific implementation scheme, the actual tension tact of the strip steel is comprehensively determined, and the mapping relationship between the set tension tset and the actual tension tact of the 20 high mill is established, so as to improve the tension control accuracy of the 20 high mill and ensure the shape quality of the strip steel. |
