Problems solved by technology
[0008] The present invention is made to solve the above problems, and its object is to provide a method of manufacturing uncirculated grade precious metal products. In the conventional method, when using a rolling mill to apply the prepared ingot to the rolling process, in order to produce Precious metal plates with accurate thickness of different weights and dozens of rolls are set, so when manufacturing refined grade or uncirculated grade precious metal products, it is necessary to mix and use dozens of rolls, and in the case of insufficient rolls, use It takes a long time to calibrate the upper and lower gaps of the rolls, and the manufacturing cost of the manufacturing device is high

The present invention relates to a manufacturing method of uncirculated (UNC) precious metal products, and more particularly, the manufacturing method includes the following effects that when the prepared ingot is applied to the rolling process, one or two rolls can fully meet the surface standard of the non-circulating grade, so that the production cost is reduced, and the production can be more easily realized than before. The non-circulating grade precious metal products are suitable for manufacturing a small amount of precious metal products in the form of rods, coins, medals, copper coins and hole coins. When the annealing process of the noble metal product is carried out, the high-temperature annealing apparatus is not used, but is exposed to the flame of the oxygen welding lamp for 2 to 3 seconds to obtain an annealing effect similar to that of the annealing apparatus; water and surfactants in the cleaning process of the non-flowing grade noble metal products can reduce the production cost and improve the environmental problems; and the manufacturing method of the non-circulating grade precious metal product can also be applied to the production of a refined production of a refined grade noble metal product.
Description
technical field [0001] The present invention relates to a technology of a manufacturing method of uncirculated grade precious metal products. The conventional technology is to produce ingots corresponding to various weights when using a rolling mill (rolling mill) to apply the prepared ingot (ingot) to the rolling process. For precious metal plates with accurate thickness, dozens of rolls are set, so when manufacturing refined (proof) grade or uncirculated (UNC:uncirculated) grade precious metal products, dozens of rolls need to be mixed and used, and when the held rolls are insufficient In this case, it takes a long time to adjust the upper and lower gaps of the rolls, and the manufacturing cost of the manufacturing device is high. Unlike the past, when the technology of the present invention is used to manufacture uncirculated (UNC) grade precious metal products, when the prepared ingot is applied to the rolling process, only one or two rolls can fully meet the uncirculated ...
