Description
Technical Field
The utility model relates to a precious metal smelting crucible, in particular to a high-purity quartz crucible for a vacuum smelting furnace.
Background
At present, although the shape and structure of precious metals, particularly gold smelting crucibles in the market are various, the crucibles are generally provided with a small discharge port, and for a vacuum smelting furnace, the crucibles with the structure need to use a special discharge nozzle due to a certain distance between the crucibles and a casting mold, otherwise, the melt cannot be guided into the casting mold in a vacuum cavity. Therefore, in order to meet the requirement of using a vacuum melting furnace to melt ingots under vacuum, a high-purity quartz crucible with a longer feeding nozzle suitable for the vacuum melting furnace is urgently needed to be designed, so that melt in the crucible can be smoothly poured into a casting mold, and the production of the ingots under vacuum is realized.
Disclosure of Invention
The utility model aims at providing a simple structure, preparation and maintenance cost are low, the operation is safe makes things convenient for high-purity quartz crucible for vacuum melting furnace of efficient for in the casting mould can be poured into smoothly to the fuse-element in the crucible, satisfy the requirement that uses vacuum melting furnace to smelt the ingot casting under the vacuum, realize ingot casting production under the vacuum.
In order to achieve the above purpose, the utility model relates to a high-purity quartz crucible for a vacuum melting furnace, which comprises a quartz crucible body and a feeding nozzle at the upper part of the quartz crucible body, wherein the quartz crucible body and the feeding nozzle are cast into a whole; the thickness of the wall of the quartz crucible body is 15mm, the thickness of the bottom of the quartz crucible body is 20mm, the inner diameter of the quartz crucible body is 70mm, the height of the quartz crucible body is 190mm, and the distance from the center of the crucible body to the tail end of the blanking nozzle is 100-150 mm so as to meet the casting requirement that the distance between the crucible and a casting mold is long; the distance between the tail end of the blanking nozzle and the upper edge of the crucible body is 10mm, and the distance between the starting end of the blanking nozzle and the upper edge of the crucible body is 15.72 mm; the tail end of the blanking nozzle is 20mm wide outside and 10mm wide inside, a taper angle formed between two inner side edges of the blanking nozzle is 6 degrees, and the radius of a transition fillet between the two inner side edges and the outer wall of the quartz crucible body is 10 mm.
The distance from the center of the crucible to the tail end of the blanking nozzle is 130 mm.
The high-purity quartz crucible for the vacuum melting furnace with the structure has the following technical characteristics and beneficial effects:
1. the smelting and casting process in the vacuum smelting furnace can be perfectly realized, and the method can be popularized in the all-gold smelting industry.
2. Simple structure, low manufacturing and maintenance cost, safe, convenient and efficient operation.
