    摘要： The invention relates to a method for preparing workpieces suitable for phosphatizing for chipless cold forming by acid pickling, rinsing, drying and treatment with acid reaction lubricants containing phosphate ions. According to said method the workpieces are rinsed before drying with a solution which contains lactic acid, has a pH below 3 and preferably a temperature of between 60 and 80° C. Preferred embodiments of the invention consist of rinsing the workpieces with a solution which in addition contains phosphoric acid, has a lactic acid concentration of between 1 and 50 g/l and a weight ratio of lactic acid to phosphoric acid of between 1:9 and 9:1.

    摘要： 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.
