Embodiment 1

[0036] like figure 1 Shown, the preparation method of high-purity standard platinum ingot, carries out successively according to the following steps:

[0037] A, take raw material: high-purity platinum raw material is mainly high-purity platinum sponge powder, a small amount is high-purity platinum alloy scrap, raw material purity 99.96%; Take high-purity platinum raw material 1050 grams for subsequent use;

[0038] B. Atmospheric smelting: Add the high-purity platinum raw material weighed in step A into the quartz crucible of the intermediate frequency furnace, raise the temperature to 1850°C, and keep it warm for 30 minutes. The platinum smelting process is carried out in the atmosphere;

[0039] C. Casting: Use clamps to clamp out the quartz crucible that has reached the holding time in step B, and cast the molten platinum in a specially designed graphite mold. After the platinum solidifies, pour it out, and clamp the platinum ingot into cold water with clamps Cooling to o...

Embodiment 2

[0048] The preparation method of high-purity standard platinum ingot is carried out successively according to the following steps:

[0049] A, take raw material: high-purity platinum raw material is mainly high-purity platinum sponge powder, a small amount is high-purity platinum alloy scrap, raw material purity 99.97%; Take high-purity platinum raw material 1100 grams for subsequent use;

[0050] B. Atmospheric smelting: Add the high-purity platinum raw material weighed in step A into the quartz crucible of the intermediate frequency furnace, raise the temperature to 1950°C, and keep it warm for 25 minutes. The platinum smelting process is carried out in the atmosphere;

[0051] C. Casting: Use clamps to clamp out the quartz crucible that has reached the holding time in step B, and cast the molten platinum in a specially designed graphite mold. After the platinum solidifies, pour it out, and clamp the platinum ingot into cold water with clamps Cooling to obtain a rough billet...

Embodiment 3

[0060] The preparation method of high-purity standard platinum ingot is carried out successively according to the following steps:

[0061] A, Weigh raw material: high-purity platinum raw material is mainly high-purity platinum sponge powder, a small amount is high-purity platinum alloy scrap, raw material purity is greater than 99.99%; Take high-purity platinum raw material 1150 grams for subsequent use;

[0062] B. Atmospheric smelting: Add the high-purity platinum raw material weighed in step A into the quartz crucible of the intermediate frequency furnace, raise the temperature to 2000°C, and keep it warm for 20 minutes. The platinum smelting process is carried out in the atmosphere;

[0063] C. Casting: Use clamps to clamp out the quartz crucible that has reached the holding time in step B, and cast the molten platinum in a specially designed graphite mold. After the platinum solidifies, pour it out, and clamp the platinum ingot into cold water with clamps Cooling to obta...

Abstract

The invention relates to the technical field of preparation for standard platinum with high purity and in particular relates to a preparation method for standard platinum with high purity. The preparation method comprises the following steps of (A) weighing raw material, (B) melting in air, (C) casting, (D) forging, (E) shearing, (F) polishing, (G) cutting in a precise way, (H) marking and (I) cleaning. The production technology is simple and causes less loss; and the standard platinum with high purity has beautiful contour, and economic benefits can be improved.

Description

technical field [0001] The invention relates to the technical field of preparation of high-purity standard precious metal ingots, in particular to a preparation method of high-purity standard platinum ingots. Background technique [0002] Precious metals have 8 chemical elements, including gold, silver and platinum group metals (platinum, platinum, rhodium, iridium, ruthenium and osmium). Due to the unique physical and chemical properties of precious metals and the currency function of maintaining and increasing value, they are widely used in my country's national economic construction. In all walks of life, the high-purity precious metal raw materials provided by my country's precious metal exchanges are standard gold ingots, standard silver ingots, standard platinum ingots, standard platinum ingots and sponge rhodium powder, sponge iridium powder, Haijin ruthenium powder with a purity greater than 99.95%. and sponge osmium powder. my country is a country with a large amount...
