Description

Technical field

[0001] The invention relates to the technical field of non-ferrous metal material processing, and mainly proposes a process method for making a cupronickel condenser tube by coil drawing. Background technique

[0002] The white copper condenser product is a copper-nickel alloy, which is called white copper because of its white color. Because of its good corrosion resistance and seawater resistance, and stable chemical composition, it is widely used in heat exchangers for thermal power and atomic power generation and marine condensers, water supply heaters, distillers, oil coolers, and distilled water devices. The market prospect is very broad, and the supply of products is in short supply.

[0003] The usual production process of the existing copper-nickel condensing tube adopts: melting and casting → sawing → extrusion → sawing → pickling → rolling → sawing to length → straight stretching (middle pass) → length → sawing → Eddy current flaw detection→anneal...
