Abstract
A kind of chill gold process of gold ultra-deep, includes the following steps：Gold material product is heated to 250 DEG C~350 DEG C by step (1)；Step (2), again by liquid nitrogen either vaporized liquid nitrogen by product fast cooling to subzero 185 DEG C~200 DEG C.The present invention is cooling material with liquid nitrogen, a kind of stiffened treatment process that gold material is carried out at low ambient temperatures, purpose is hardened to reach gold, the technique can be with stable prod size, Reducing distortion, surface abrasion resistance significantly increase, and do not destroy product appearance, it is environment friendly and pollution-free, on gold product purity without influence.The hardness of gold can be promoted between 80 DEG C~100 DEG C of Webster for 20 DEG C~30 DEG C from Webster.
Description
Technical field
The present invention relates to a kind of gold processing technology more particularly to a kind of chill gold process of gold ultra-deep.
Background technology
Gold jewelry is most commonly seen gold product, and the gold jewelry of high-purity is very popular, and people are always
The gold product pursued and like purity higher.But there are hardness is not high and what is be easily deformed lacks for the gold jewelry of high-purity
It falls into.In the prior art, producer uses adds the method for other compositions to solve gold jewelry hardness not in gold jewelry
The problem of foot, but this method reduces the purity of gold jewelry again, in this way, the situation to face a difficult selection.
Invention content
Based on this, it is necessary to be directed to deficiency in the prior art, provide a kind of chill gold process of gold ultra-deep.
A kind of chill gold process of gold ultra-deep, includes the following steps：
The finished product of gold material product either semi-finished product are heated to 250 DEG C~350 DEG C by step (1)；
Step (2), again by liquid nitrogen either vaporized liquid nitrogen by product fast cooling to subzero 185 DEG C~200 DEG C.
Further, in step (1), gold material product is heated to 280 DEG C~300 DEG C.
Further, in step (2), gold material product is cooled to 190 DEG C~195 DEG C.
Further, after completing step (2) processing, step (1), (2) is repeated, gold material product is processed again.
Further, in step (2), entire temperature-fall period continues 5min~30min.
The advantageous effect of the chill gold process of gold ultra-deep of the present invention is：It is cold that gold subzero treatment technology, which is with liquid nitrogen,
But material hardens purpose, the work to a kind of stiffened treatment process that gold material carries out at low ambient temperatures to reach gold
Skill can be with stable prod size, Reducing distortion, and surface abrasion resistance significantly increases, and does not destroy product appearance, environment friendly and pollution-free, to Huang
Golden product purity is without influence.The hardness of gold can be promoted between 80 DEG C~100 DEG C of Webster for 20 DEG C~30 DEG C from Webster.
Specific implementation mode
In order to make the object, technical solution and advantage of invention be more clearly understood, with reference to embodiments, invention is carried out
It is further described.It should be appreciated that specific embodiment described herein is not used to limit hair only to explain invention
It is bright.
The present invention provides a kind of chill gold process of gold ultra-deep, and for carrying out stiffened processing to gold, the gold ultra-deep is cold
Hard gold process includes the following steps：
Step (1), by the finished product of gold material product between either semi-finished product are heated to 250 DEG C~350 DEG C, preferably
Ground is heated to 280 DEG C~300 DEG C；
Step (2), again by liquid nitrogen either vaporized liquid nitrogen by product fast cooling to subzero 185 DEG C~200 DEG C, it is excellent
Selection of land is cooled to 190 DEG C~195 DEG C, by thermal expansion and contraction principle, product surface fast speed, high intensity is made to shrink, entire to cool down
Process continues 5min~30min.
In order to reach better processing effect, after completing step (2) processing, step (1), (2) are repeated, gold material is produced
Product are processed again.
The advantageous effect of the chill gold process of gold ultra-deep of the present invention is：It is cold that gold subzero treatment technology, which is with liquid nitrogen,
But material hardens purpose, the work to a kind of stiffened treatment process that gold material carries out at low ambient temperatures to reach gold
Skill can be with stable prod size, Reducing distortion, and surface abrasion resistance significantly increases, and does not destroy product appearance, environment friendly and pollution-free, to Huang
Golden product purity is without influence.The hardness of gold can be promoted between 80 DEG C~100 DEG C of Webster for 20 DEG C~30 DEG C from Webster.
The several embodiments invented above described embodiment only expresses, the description thereof is more specific and detailed, but not
It can therefore be construed as limiting the scope of the patent.It should be pointed out that for those of ordinary skill in the art,
Under the premise of not departing from inventive concept, various modifications and improvements can be made, these belong to the protection domain of invention.Cause
This, the protection domain of patent of invention should be determined by the appended claims.
