Degreasing commonly means of removing from the wire surface lubricants used during the previous processing of the wire, say grease, oil or stearates. There are different degreasing technologies; the choice depends on the nature of the “grease” to be removed and the requested degree of cleanliness. Some processes as, for example, electrolytic plating, requires a perfectly clean initial surface; therefor the degreasing of copper or steel wire upstream an electrolytic process (tinning, or nickel plating, or zincking) is done in an electrolytic bath (electrolytic degreasing). The ultrasonic degreasing is a well proven method of cleaning; for instance it is commonly used to prepare the wire to the hot dipping galvanizing. The continuous heat treatment of wire occurs commonly with the wire surface being rather clean; before entering the furnace the wire undergoes a degreasing in a water bath (degreasing in water). The water may be hot or cold, depending on the type of the next process. Annealing or inductive patenting, or patenting in a lead bath may require different degrees of cleanliness. Consequently, they requires different degrees of degreasing efficiency, or, in other words, different temperatures of the degreasing water.
