Description
Technical field
Soften the processing method of Silver Jewelry the present invention relates to processing method for accessory technical field, more particularly to reactance.
Background technology
Fine silver is commonly used for decoration material and by consumers but fine silver with its excellent performance and low price advantage
Its mechanical strength and hardness are decreased obviously this phenomenon referred to as nature after the normal temperature storage several months after cold deformation is processed
Age softening finds that the content that this softening degree depends on fine silver cold deformation and impurity is to prevent Silver Jewelry material through overtesting
The natural ageing and softening people of material have studied to be added copper, zirconium titanium, nickel and rare earth element to suppress the natrual ageing of silver-colored material in silver
Softening properties.
The content of the invention

The step of processing method of the anti-softening Silver Jewelry of the present invention, this method, includes：
Step S101, uses purity to use purity to close with Ag-la and Ag-Y alloy preparations rare earth silver for 99.90% silver
Gold；
Step S102, is cast with graphite crucible in Medium frequency induction circuit in melting under cryogenic vacuum in burner hearthCylindrical ingot.
Step S103, passes through 3~5 radial direction jumping-ups, upset diameter is by the cylindrical ingot obtained by step S102Obtain band processing silver ingot.
In a preferred embodiment, in the step S101 Ag-Y alloys comprising rare earth element 0.5~0.7% or
0.8~0.9%.
In a preferred embodiment, include in the step S103：Cylindrical ingot is annealed.
In a preferred embodiment, the annealing includes：Anneal first, the annealing temperature is 450 DEG C, 2.5h：
Stand 8~10h；Anneal again, the annealing temperature is 500 DEG C, 1~1.2h.
In a preferred embodiment, include in the step S103：Step S1031, by the cylinder after jumping-up
Shaped cast ingot is cold rolled to the sheet material that thickness is 4mm.
In a preferred embodiment, step S1031 includes：Sheet material is annealed again.
In a preferred embodiment, the annealing includes：Anneal first, the annealing temperature is 450 DEG C, 2.5h：
Stand 8~10h；Anneal again, the annealing temperature is 500 DEG C, 1~1.2h；Mill product size is 1.10mm.
In a preferred embodiment, after the step S103, in addition to step S104：Step S104, to plate
Material is quenched.
In a preferred embodiment, the quenching includes：Quench first, the hardening heat is 600 DEG C, 1h：It is quiet
Put 1~2h；Anneal again, the hardening heat is 500 DEG C, 1~1.2h..
In a preferred embodiment, Ag-Y alloys include rare earth element 0.3~0.35% in the step S101.
So as to which the beneficial effects of the present invention are the present invention in silver alloy by mixing addition trace rare-earth lanthanum and yttrium pair
The influence of silver-colored material microstructure and property.Simultaneously by repeatedly annealing, rare earth element is set preferably to be merged with ag material, so that,
Its amalgamation and plasticity are improved, so as to improve the overall performance of silver alloy.
