The invention discloses a production method of aluminum alloy hot rolling gradient winding tension control. By setting winding tension of strips at different length stages, the winding tension is controlled differently in the same reel. Different ways for controlling the winding tension are achieved according to a specific gradient tension change slope. Hot-rolled coiled materials produced with the production method have good finished product performance and good surface quality, the strips are smoothly wound, adhesive damage generated due to excessive tension is avoided, and the phenomena ofquality abnormalities such as interlayer adhesive damage and the thickness difference caused by non-uniform cooling in the cooling process of the hot-rolled coils are avoided. 本发明公开了一种铝合金热轧梯度卷取张力控制的生产方法，通过设定带材不同长度阶段的卷取张力，实现同一卷中，卷取张力不同控制。按照特定的梯度张力变化斜率，达到不同的控制卷取张力的手段。按照本发明生产的热轧卷材，具有成品性能好，表面质量好，使带材卷取平整，且不因张力过大而产生粘伤，避免在热轧卷冷却过程中，因冷却不均造成层间粘伤及厚差等质量异常现象。
