Abstract
본 발명은 종래의 순금(24K)은 색상도 미려하고 재산가치가 높은 데도 실제로 제품화 하기에는 너무 강도(Hv 32)가 낮아 무르므로 순금장식재로 사용이 불가능하였으며 신선 및 압연공정을 거치면 어느 정도(Hv 80)의 상승효과를 기대할 수 있으나 그 강도로도 대형 제품 외에는 적합하지 않고 순금장식재로 사용하기 위해서는 강도 Hv 100이상이 되어야 만 하고 시간이 경과해도 그 강도가 저하되지 않아야 한다. 현재 국내에는 순금(24K)장식품은 거의 없는 상태이고 간혹 출시되는 제품도 일부 대형품에 불과하며 강도가 낮아 얇거나 가늘은 정밀한 장식제품의 생산은 불가능한 상태이며 일본에서 공지된 24K 경화금도 금함량 99.7%를 유지하고는 Hv 값이 100을 넘기기 어려워 엄밀한 의미로 순금(24K)이라고 보기는 어려웠던 문제점을 해결하기 위해 진공로나 일반 유도로에서 순금(24K)과 미량원소(Mg. Al. Si. Mn. Fe. Co. Ni. Cu. Pd. IN. Sn. Sb. Pb. Bi. Be. Ge. Ti.)중 1종 혹은 2종을 0.3% 이내에서 합금 용해한 후 질소가스를 주입 하므로써 Hv 100이상인 고강도와 순도 99.97% 이상인 순금(24K)장식재로 사용할 수 있도록 그 제조 방법을 발명한 것이다.According to the present invention, the conventional pure gold (24K) is beautiful in color and has a high property value, but it is not easy to use as a pure gold decoration material because the strength (Hv 32) is too low to be practically commercialized. The synergistic effect of) can be expected, but its strength is not suitable for other than large products, and its strength should be Hv 100 or higher to be used as pure gold decoration material and its strength should not decrease over time. Currently, there are few pure gold (24K) decorations in Korea, and the products that are sometimes released are only a few large items. Due to their low strength, it is not possible to produce thin or thin decorative products, and the 24K hard gold known in Japan is also prohibited. The pure gold (24K) and trace elements (Mg. Al. Si. Mn) in vacuum furnaces or general induction furnaces were solved to solve the problem that it was difficult to see pure gold (24K) in the strict sense because the Hv value was difficult to exceed 100 with 99.7%. One or two of Fe.Co.Ni.Cu.Pd.IN.Sn.Sb.Pb.Bi.Be.Ge.Ti. It is invented the manufacturing method to be used as a pure gold (24K) decoration material of high strength and purity of 99.97% or more.
Description
본 발명은 미량원소 및 질소(N₂. NH₃기타질소(N)원소제공원료)주입에 의한 고강도 순금(24K)장식재의 제조방법에 관한 것으로 순금을 진공로나 유도로에 용융시에 미량원소를 투입하고 질소가스를 주입하여 미려한 순도 99.95%를 유지하면서 원하는 고강도로 증진 시켜 순금장식재로 사용하도록 한 것이다.The present invention relates to a method for producing high strength pure gold (24K) decorative material by injection of trace elements and nitrogen (N₂. NH₃ other nitrogen (N) element park), and the fine element is injected when melting pure gold into a vacuum furnace or an induction furnace. Nitrogen gas is injected to maintain the beautiful purity of 99.95% while enhancing the desired high strength to be used as a pure gold decoration material.
종래의 순금(24K)은 색상도 미려하고 재산가치가 높은 데도 실제로 제품화 하기에는 너무 강도(Hv 32)가 낮아 무르므로 순금장식재로 사용이 불가능하였으며 신선 및 압연 공정을 거치면 어느 정도 강도(Hv 80)의 상승효과를 기대할 수는 있으나 그 강도로도 대형제품 외에는 적합하지 않고 순금장식재로 사용하기 위해서는 강도 Hv 100 이상이 되어야 만 하고 시간이 오래 경과해도 그 강도가 저하되지 않아야 한다. 현재 국내에는 순금(24K)장식품은 거의 없는 상태이고 간혹 출시되는 제품도 일부 대형품에 불과하며 강도가 낮아 얇거나 가늘은 정밀한 장식제품의 생산은 불가능한 상태이며 일본에서 공지된 24K 경화금도 금함향 99.7%를 유지하고는 Hv 값이 100 을 넘기기 어려워 엄밀한 의미로 순금(24K)이라고 보기는 어려웠던 것이다.Conventional pure gold (24K) has a beautiful color and high property value, but it is too low (Hv 32) to be commercialized, so it is not available as pure gold decoration material. A synergistic effect can be expected, but its strength is not suitable for other than large products and its strength should be at least Hv 100 in order to be used as a pure gold decoration, and its strength should not deteriorate over time. Currently, there are few pure gold (24K) ornaments in Korea, and the products that are sometimes released are only a few large items. Due to their low strength, it is impossible to produce thin or thin decorative products, and the 24K hard gold known in Japan is also prohibited. At 99.7%, it was difficult to see pure gold (24K) in the strict sense because the Hv value was hard to exceed 100.
본 발명은 상기와 같은 문제점을 해결하기 위해 진공로나 일반 유도로에서 순금(24K)과 미량원소(Mg. Al. Si. Mn. Fe. Co. Ni. Cu. Pd. IN. Sn. Sb. Pb. Bi. Be. Ge. Ti.)중 1종 혹은 2종을 0.3% 이내에서 합금 용해한 후 질소를 주입하므로써 Hv 100 이상인 고강도와 순도 99.97% 이상인 순금(24K)장식재로 사용할 수 있도록 그 제조 방법을 발명한 것으로 실시예에 따라 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention provides a pure gold (24K) and a trace element (Mg.Al.Si.Mn.Fe.Co.Ni.Cu.Pd.IN.Sn.Sb.Pb) in a vacuum furnace or a general induction furnace. By dissolving one or two of Bi.Be.Ge.Ti.) within 0.3% of alloy, and then injecting nitrogen, the manufacturing method can be used for high strength of Hv 100 or more and pure gold (24K) decoration with purity of 99.97% or more. When described in detail according to the embodiment according to the invention as follows.
실시예Example
진공로나 유도로에서 순금(24K)과 미량원소(Mg. Al. Si. Mn. Fe. Co. Ni. Cu. Pd. IN. Sn. Sb. Pb. Bi. Be. Ge. Ti.)중 1종 혹은 2종을 0.3% 이내에서 합금 용해한 후 질소(N₂. NH₃기타질소(N)원소제공원료)를 10분 정도 합금원소로 주입하여 제조하는 것이다.1 of pure gold (24K) and trace elements (Mg. Al. Si. Mn. Fe. Co. Ni. Cu. Pd. IN. Sn. Sb. Pb. Bi. Be. Ge. Ti.) In a vacuum or induction furnace It is prepared by dissolving the species or two species within 0.3%, and then injecting nitrogen (N₂, NH₃ other nitrogen material park material) into the alloy element for about 10 minutes.
이와 같은 실시예를 거처 제조되는 순금(24K)장식재를 직경 20mm ∼ 길이 10mm의 원주상의 덩어리(ingot)로 주로한 후 중간 부분을 취하여 덩어리 조직의 경도를 측정(마이크로 비이커스 경도계 하중 100g)하고 원주상의 덩어리(ingot)를 신선기로 직경 Ø 3.3mm ∼ 0.19mm 와이어와 같은 방법으로 두께 1mm ∼ 0.17mm의 판재로 가공하여 얻어진 와이어나 판재중에서 두께 및 직경이 0.5mm인 제품을 취하여 경도측정(마이크로 비이커스 경도계 하중 100g)하였으나 동일하였으며 상기에 취한 견본을 6개월 이상 방치한 후에 다시 경도를 측정했으나 아무런 변화가 발생하지 않았다.The pure gold (24K) decorative material manufactured according to this embodiment was mainly made into a columnar ingot of 20 mm in diameter to 10 mm in length, and then the middle part was taken to measure the hardness of the agglomerate structure (microbeaker hardness tester 100 g). Hardness measurement was performed by taking a product with a thickness and a diameter of 0.5 mm from a wire or sheet obtained by processing a cylindrical ingot with a drawing machine with a diameter of Ø 3.3 mm to 0.19 mm in the same way as a wire with a diameter of Ø 3.3 mm to 0.19 mm. Micro Vickers hardness tester 100g) was the same, the hardness was measured again after leaving the sample taken for 6 months or more, but no change occurred.
이와 같은 본 발명의 순금(24K)장식재는 Hv 100 이상의 고강도가 유지 되면서 순금 99.97%의 순도와 미려한 색상에 아무런 영향을 주지 않으므로 금장식재로 이용도가 넓은 효과가 있다.Such pure gold (24K) decorative material of the present invention, while maintaining the high strength of Hv 100 or more has no effect on the purity and beautiful color of pure gold 99.97% has a wide range of applications as a gold decorative material.
