铝箔板形相对中凸度控制方法
摘要：
本发明涉及铝箔板形相对中凸度控制方法，属于板型中凸度控制方法技术领域。本发明铝箔板形相对中凸度控制方法，步骤：1、选料：在轧制成的铝箔板中选出板形好的两种不同宽度的铝箔板；2、查得上述两种不同宽度的铝箔板的热轧中凸度；3、计算板宽为X的铝箔板的热轧中凸度ΔX％；设铝箔板的板宽为X，则ΔX％＝ΔHc％+(ΔHb％-ΔHc％)*(X-I)/(L-I)；4、优化修正得到板宽为X的铝箔板的中凸度。本发明铝箔板形相对中凸度控制方法，控制方法简捷，板形精度高，根据两种不同宽度、理想板形的中凸度，即可得到板宽为X的铝箔板的中凸度。
摘要（英）：

The invention relates to a method for controlling profile shape relative convexity of an aluminum foil, which belongs to the technical field of methods for controlling the profile shape convexity. The method for controlling the profile shape relative convexity of the aluminum foil comprises the following steps of: 1, selecting materials, namely selecting two types of aluminum foil plates with good profile shapes and different widths from rolled aluminum foil plates; 2, checking the hot rolling convexity of the two types of the aluminum foil plates with different widths; 3, calculating the hot rolling convexity of deltaX% of the aluminum foil plate with the plate width of X, wherein if the plate width of the aluminum foil plate is X, the deltaX% is equal to deltaHc%+(deltaHb%-deltaHc%)*(X-1)/(L-1); and 4, performing optimization and modification to obtain the convexity of the aluminum foil plate with the plate width of X. The method for controlling the profile shape relative convexity of the aluminum foil has is simple and direct, has high profile shape accuracy, and can obtain the convexity of the aluminum foil plate with the plate width of X according to the convexity of two types of ideal profile shapes with different widths.
