    • The invention relates to a method for regenerating reaction lubricant residues containing acid organic lubricants refused and processed during cold forming and multivalent metal ions and phosphate ions, wherein said reaction lubricant residues undergo the following procedural steps: a) precipitating metal ions from the metal organic compounds by adding phosphoric acid and/or acid phosphoric acid esters; b) dissolving water-soluble impurities by adding water; c) separating the solids from the lubricant components and from the aqueous phases that are incompatible with the oily lubricant components, and whereby d) acid phosphoric acid esters for adjusting the free acid at a value of less than 10 points and for adjusting a total acidity point value of less than 70 is adjusted at a free acid. total acidity ratio having a value in the range of 0.15 to 0.5. The separation indicated in step c) preferably occurs by means of a centrifuge at 2,000 to 3,000 g, especially at 8,000 to 15,000 g.
    • 本发明涉及一种用于再生含有在冷成型期间拒绝和加工的酸性有机润滑剂和多价金属离子和磷酸根离子的反应润滑剂残留物的方法,其中所述反应润滑剂残余物经历以下程序步骤:a)从金属有机化合物沉淀金属离子 通过加入磷酸和/或酸式磷酸酯; b)通过加水溶解水溶性杂质; c)将固体与润滑剂组分和与油性润滑剂组分不相容的水相分离,并且由此d)用于调节游离酸的值小于10分的酸性磷酸酯和用于调节总酸度 小于70的点值在游离酸下调节。 总酸度比的值在0.15〜0.5的范围内。 步骤c)中所示的分离优选通过2,000至3,000g,特别是8,000至15,000g的离心机进行。
