摘要:

隨著生產技術的不斷進步以及對產品質量要求越來越高，用戶對壓延銅箔的表面質量和板形要求日益嚴格。針對壓延銅箔在X型六輥箔軋機軋制過程中出現的嚴重板形問題，以寬度630 mm、厚度18 μm的紫銅箔軋制過程為例，著重分析了加工道次、張力控制以及支撐輥輥型對雙肋浪、雙邊浪、中間浪等板形問題的影響，并提出了相應的解決方案。結果表明：① 在總加工率不變的情況下，減少加工道次，可以增加每道次產生的變形熱，有利于殘余應力的釋放，進而改善板形；② 適當的加大張力，并調節入口張力與出口張力相等，可以有效地對板形進行調節；③ 設置支撐輥總凸度值為0.3 mm以及磨削支撐輥二級輥型均可有效改善板形。

Abstract:

With the continuous improvement of production technology and higher requirement for product quality, users are increasingly strict about the quality of surface and plate shape of rolled copper foil. In view of the serious plate shape problems of rolled copper foil by X-type rolling mill, taking the rolling process of copper foil with width of 630 mm and thickness of 18 μm as an example, the influences of the rolling passes, the tension control and the backup roll profile on the plate shape problems of the double�瞨ib wave, the middle and double waves are analyzed emphatically, and the corresponding solution is put forward in the paper. The results showed that: ① under the condition of the same total processing rate, the plate shape problems can be effectively improved by reducing rolling passes, which can generate more deformation heat per rolling pass to release residual stress; ② the plate shape can be effectively regulated by appropriately increasing the tension, and adjusting the inlet tension and export tension equal; ③ setting the backup roll crown as 0.3 mm, and grinding secondary roller profile of backup roll can also be beneficial to plate shape.
