Copper Sheet Rolling Recipe
紫铜板辊压参数配方
标签：紫铜,辊距,辊速,润滑,减薄率
厚度 0.8 mm 紫铜板（T2），辊距设为 0.74–0.76 mm，辊速 4–6 m/min，单次压花减薄率控制在 5% 以内以避免开裂。辊面与板材均需涂薄层菜籽油作润滑，压后自然冷却。若纹理偏浅，将辊距下调 0.02 mm 复压一次。
For 0.8 mm T2 copper sheet, set roller gap 0.74–0.76 mm, speed 4–6 m/min, single-pass reduction under 5% to avoid cracking. Apply a thin film of rapeseed oil on both roller and sheet; cool naturally after rolling. If relief is shallow, lower the gap by 0.02 mm and re-roll once. ---
