Under nitrogen protection, the copper wire drawn is heated to 410 DEG C, insulation 45min, then keep nitrogen atmosphere to be cooled to room temperature, and cleaned by copper wire, coiling is put in storage.
4. oil strainer according to claim 1 corrosion-resistant copper wire and manufacturing process thereof, is characterized in that, comprises following technological process:
Adopt reflection smelting furnace to carry out melting, smelting temperature is 1100 DEG C, obtains liquid copper, and carries out salvaging filtration to the slag of copper surface flotation liquid in stove, chemical composition and the mass percent of the alloy billet selected are: Cr:6.24%, Ni:2.10%, C:0.03%, Mo:0.55%, Al:6.97%, V:0.52%, W:0.22%, Si:0.16%, Mn:0.79%, Nb:0.28%, Ti:1.13%, Ca:0.12%, Se:0.26%, Te:0.07%, all the other are Cu and inevitable impurity;
Then, furnace temperature is risen to 1210 DEG C, blowing argon gas stirs, and stirring velocity is 230r/min, and churning time is 25min, and argon flow amount is 190L/h;
Liquid copper is released by the copper outlet reflecting smelting furnace, through chute, by chute gate, enters in crystallization groove, adopt water coolant to cool simultaneously, make copper crystallize into copper ingot;
Copper ingot is heated to 760 DEG C, is forged into copper bar, be then cooled to 470 DEG C, nitrogen blowing, argon flow amount is 250 L/h, insulation 4h;
Copper bar is carried out wire drawing, first copper bar is drawn into the copper wire of Φ 1.2mm, then the copper wire of Φ 1.2mm is drawn into the copper wire of Φ 0.5mm, then Φ 0.5mm is drawn into the copper wire of Φ 0.2 mm, then the copper wire of Φ 0.2 mm is drawn into the copper wire of Φ 0.04mm;
Under nitrogen protection, the copper wire drawn is heated to 400 DEG C, insulation 50min, then keep nitrogen atmosphere to be cooled to room temperature, and cleaned by copper wire, coiling is put in storage.
