| titleOfInvention | A kind of corrosion-resistant White Copper Tubes and preparation method thereof |
| abstract | The present invention relates to corronel field, particularly relate to a kind of ocean corrosion-resistant White Copper Tubes and preparation method thereof.By weight percentage, its chemical composition and content as follows: carbon C :≤0.03; Silicon Si:0.10 ~ 0.20; Manganese Mn:6.0 ~ 8.0; Sulphur S :≤0.005; Phosphorus P:0.15 ~ 0.20; Nickel: 22.0 ~ 24.0; Cobalt Co:2.0 ~ 4.0; Zinc Zn:2.0 ~ 4.0; Plumbous Pb:0.20 ~ 0.40; Iron Fe:3.0 ~ 4.0; Rare earth elements RE: 0.15 ~ 0.20; Arsenic As:0.005 ~ 0.010; Copper Cu: surplus.After adopting induction melting to obtain copper-nickel alloy pipe, dialogue copper tube billet carries out coil pipe and stretches and produce: founding → sawing → water seal extruding → tube rolling → disk stretchings → disk sword mould strips off the skin → and the stretching of disk stretchings → Shu Mage associating cold drawing bench stretching → vertical bar → anneal.It is limited that the present invention solves traditional cupronickel material lifetime, is difficult to adapt to the problems such as the coil pipe stretching mode of production because plasticity is low, its coil pipe stretched and is achieved. |
