Eco Lubricants & Recycled Blanks in Spinning
环保旋压润滑与再生坯料应用

旋压润滑环保化方案：聚醚+硼酸酯水性润滑液（5–8% 浓度）替代氯化石蜡皂化液，摩擦系数 0.10–0.14，工件水洗即净、无油斑残留，对后续镀锡与做旧工序友好。再生铜板（1 号铜）作坯料时延展性略差，道次减薄率由 12–20% 下调至 8–15% 并增加一个道次。边角料回炉前须 400 °C 烧除表面润滑膜并分类存放，混入橡胶垫碎屑会污染整炉熔体。三项合计可把车间危险废物量削减约 60%。
Greener spinning lubrication: a polyether/borate water-based fluid (5–8% concentration) replaces chlorinated-paraffin soap — friction 0.10–0.14, parts rinse clean with water, no oil staining, and downstream tinning and patina work stays unaffected. With No.1 recycled-copper blanks, ductility dips slightly: drop pass reduction from 12–20% to 8–15% and add one pass. Before remelting offcuts, burn off lubricant film at 400 °C and sort strictly — rubber-pad crumbs contaminate a whole melt. Together these cut shop hazardous waste by roughly 60%.
