Embodiment 1
[0027] A high-strength spring wire with high elastic modulus. Calculated by mass percentage, the chemical composition of the alloy wire is: C: 0.05%, Cr: 17.0%, Ni: 8.0%, Co: 6.0%, Mo: 3.0%, W : 3.5%, Nb: 2.0%, Al: 0.5%, Ti: 0.5%, Si: 0.3%, Mn: 0.3%, P: 0.01%, S: 0.01%, B: 0.005%, Ce: 0.05%, Zr : 0.01%, the balance is iron.
[0028] Mix pure iron, metal chromium and metal nickel into the bottom of the crucible, and metal molybdenum, metal niobium and metal tungsten are scattered in the upper part of the crucible. After mixing according to the proportion, vacuum induction and vacuum consumable smelting are carried out, followed by forging, and hot rolling to Φ6mm wire rod. In the cold drawing process, the deformation of the wire is controlled at 50% in the billet opening stage, 30% in the intermediate billet stage, and 40% in the finished product. The wire material needs to undergo intermediate continuous annealing before billet opening and cold drawing of the intermediate bi...

[0035] A high-strength spring wire with high elastic modulus. Calculated by mass percentage, the chemical composition of the alloy wire is: C: 0.03%, Cr: 12.0%, Ni: 5.0%, Co: 3.0%, Mo: 2.0%, W : 1.5%, Nb: 1.0%, Al: 0.3%, Ti: 0.3%, Si: 0.2%, Mn: 0.2%, P: 0.005%, S: 0.005%, B: 0.00: 3%, Ce: 0.02% , Zr: 0.008%, the balance is iron.
[0036]Mix pure iron, metal chromium and metal nickel into the bottom of the crucible, and metal molybdenum, metal niobium and metal tungsten are scattered in the upper part of the crucible. After mixing according to the proportion, vacuum induction and vacuum consumable smelting are carried out, followed by forging, and hot rolling to Φ15mm wire rod. In the cold drawing process, the deformation of the wire is controlled at 65% in the billet opening stage, 50% in the intermediate billet stage, and 100% in the finished product. The wire needs to be subjected to intermediate continuous annealing before billet opening and intermediate billet cold drawi...

[0038] A high-strength spring wire with high elastic modulus, calculated by mass percentage, the chemical composition of the alloy wire is: C: 0.01%, Cr: 15.2%, Ni: 7.2%, Co: 4.8%, Mo: 2.8%, W : 2.9%, Nb: 1.5%, Al: 0.4%, Ti: 0.4%, Si: 0.1%, Mn: 0.1%, P: 0.001%, S: 0.001%, B: 0.002%, Ce: 0.02%, Zr : 0.005%, the balance is iron.
[0039] Mix pure iron, metal chromium and metal nickel into the bottom of the crucible, and metal molybdenum, metal niobium and metal tungsten are scattered in the upper part of the crucible. After mixing according to the proportion, vacuum induction and vacuum consumable smelting are carried out, followed by forging, and hot rolling to Φ10mm wire rod. In the cold drawing process, the wire deformation is controlled at 55% in the billet opening stage, 40% in the intermediate billet stage, and 80% in the finished product. The wire needs to be subjected to intermediate continuous annealing before billet opening and intermediate billet cold drawing. The c...
