Abstract
A technique for preparing the anti-discoloring rose-gold jewellery includes such steps as heating gypsum mould to 650-680 deg.C, heating the raw rose-gold to 1050-1100 deg.C to become molten rose-gold, pouring it in said gypsum mould in vacuum environment, laying aside for 30-70 s, putting the mould in ordinary environment for 5-10 min, cooling in cold water, demoulding, and trimming.
Description
Technical field
The present invention relates to the processing method of rose gold jewellery, more particularly, relate to a kind of processing method of anti-variable color rose gold jewellery.
Background technology
The said rose gold of the present invention is a kind of metal alloy compositions that is used to produce jewellery, wherein contains gold (Au), silver (Ag), copper noble metals such as (Cu) usually.For example, in the 8K rose gold, gold content is 33%; At the 18K rose gold, gold content is 75%.
Owing to easy oxidations of metal such as silver contained in the rose gold, copper, so cause the easy variable color of rose gold.How delaying even prevent the rose gold variable color, is one technical barrier of jewellery production industry, and existing production method all fails to address this problem well.
Summary of the invention
At the above-mentioned defective of prior art, the present invention will solve the problem of the easy variable color of rose gold jewellery of adopting prior art production.
The technical solution adopted for the present invention to solve the technical problems is: a kind of processing method of anti-variable color rose gold jewellery is provided, comprising following steps:
(1) mold heated that is used to make jewellery is arrived 650-680 ℃;
(2) the rose gold raw material is heated to 1050-1100 ℃, forms the rose gold liquation;
(3) in the environment that vacuumizes, described rose gold liquation is poured in the described mould that heats, and placed 30-70 second;
(4) from the described environment that vacuumizes, take out the described mould that rose gold is housed, adjust at normal temperatures standing time, placed at normal temperatures 5-10 minute according to the size of foundry goods;
(5) the described mould that rose gold is housed is put into cooling water, carry out quench cooled and handle;
(6) take out the rose gold foundry goods from described mould, processing is treated to required Jewelry product.
In described step of the present invention (3), be preferably 40 seconds the standing time after described rose gold liquation poured in the described mould that heats.In described step of the present invention (5), employed cooling water is preferably normal-temperature water, and with the rose gold cooling processing in the described mould to normal temperature.
The mould that uses among the present invention is preferably gypsum mold.
Compared with prior art, the present invention adjusts technologies such as corresponding heating-up temperature, cool time according to the size of rose gold jewellery foundry goods, the more important thing is, the present invention goes into to have drawn the quench cooled process, with the cooling of quickening the rose gold jewellery and reduce oxidation, and experiment shows that the rose gold jewellery of producing by this method through long-term use the variable color situation do not take place.
Description of drawings
No accompanying drawing.
The specific embodiment
In a preferred embodiment of the present invention, as material, make the rose gold jewellery according to the following steps with the 8K rose gold.
(1) in heating furnace (model is: BT18G, specification is: 6KW, 380V weigh 140 kilograms) lining the gypsum mold that is used to make the rose gold jewellery is heated to 650 ℃.
(2) simultaneously, the 8K gold is heated to 1050 ℃, forms the rose gold liquation with medium-sized melting machine (model is: CXM-AI, specification is: AC380V, 50/60Hz, send out the cycle 40KHz that shakes, the type of cooling is a water-cooled).
(3) gypsum mold that will be heated to 650 ℃ is put into the suction vacuum machine, an enclosed environment is wherein arranged, be in the state (just approaching vacuum certainly but not the perfect vacuum) of being inhaled vacuum in process of production always, in this vacuum environment, the rose gold liquation that is heated to 1050 ℃ is poured in the gypsum mold, placed 30 seconds.
(4) take out the gypsum mold that rose gold has been housed from described vacuum environment, placed at normal temperatures 5 minutes.
(5) gypsum mold that rose gold will be housed is put into cooling water, carries out quench cooled and handles, and use therein cooling water is preferably normal-temperature water, and with the rose gold cooling processing in the gypsum mold to normal temperature.
(6) from gypsum mold, take out the rose gold foundry goods, and processes is treated to required Jewelry product routinely.
In the foregoing description, the rose gold gross weight that gypsum mold can hold is about 50 grams.At more jumbo gypsum mold, can be to heating-up temperature wherein, do corresponding the adjustment standing time etc.
In another embodiment of the present invention, when the rose gold gross weight that can hold when gypsum mold is the 150 gram left and right sides, in step (1), gypsum mold is heated to 665 ℃; In step (2), rose gold is heated to 1075 ℃; In step (3), after pouring into the rose gold liquation in the gypsum mold, placed 40 seconds; In step (4), placed at normal temperatures 7 minutes; In step (5) and (6), handle by same requirement.
In another embodiment of the present invention, when the rose gold gross weight that can hold when gypsum mold is the 220 gram left and right sides, in step (1), gypsum mold is heated to 680 ℃; In step (2), rose gold is heated to 1100 ℃; In step (3), after pouring into the rose gold liquation in the gypsum mold, placed 70 seconds; In step (4), placed at normal temperatures 10 minutes; In step (5) and (6), handle by same requirement.
By above-mentioned specific embodiment as can be seen, compared with prior art, the present invention adjusts technologies such as corresponding heating-up temperature, cool time according to the weight size of rose gold jewellery foundry goods, and the heating-up temperature of rose gold is brought up to 1050-1100 ℃ by traditional 980 ℃; The more important thing is that the present invention goes into to have drawn the quench cooled process, with the cooling of quickening the rose gold jewellery and reduce oxidation, and experiment shows that the rose gold jewellery of producing by this method through long-term use the variable color situation do not take place.
