Problems solved by technology

Although some amorphous jewelry can be prepared by using copper mold casting method and high pressure casting method, due to the use of metal molds, it is difficult to open the mold, the cost is high, and it is not easy to manufacture castings with complex structures of various shapes.
At present, there is no method to use amorphous alloys to produce various styles of amorphous alloy jewelry.

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific embodiments, but not limited to this embodiment.

[0020] The LaCeCoAl master alloy is coarsely crushed and loaded into a quartz nozzle. The alloy is melted by high-frequency induction heating and then spray-cast into a jewelry plaster mold. The specific steps are as follows:

[0021] 1. Put the LaCeCoAl master alloy into a quartz nozzle after coarse crushing, place the quartz nozzle in a high-frequency induction furnace, and connect the upper end of the nozzle to an inert gas conduit;

[0022] 2. Carry out high-frequency induction heating to the alloy to about 50°C higher than the melting temperature of the alloy, and keep it warm;

[0023] 3. Adjust the relative position of the quartz nozzle and the gypsum mold, insert the quartz nozzle into the injection port of the gypsum mold, and rotate relative to make the two fit tightly;

[0024] 4. Turn off the high-frequency induction power ...

Abstract

The invention relates to jewelry preparation technology, in particular to a method for preparing amorphous alloy jewelry and nozzle equipment specially used for the method for preparing amorphous alloy jewelry. First put the master alloy into the nozzle, heat until the alloy is melted and keep warm, fit the nozzle and the injection port of the jewelry plaster mold tightly, blow inert gas into the nozzle, and inject the molten alloy into the jewelry plaster mold; The nozzle used, the barrel-shaped body of the nozzle body is a barrel type, the nozzle at the end of the nozzle is a conical cone, the nozzle taper is 5-75°, and the difference between the taper of the injection port of the jewelry plaster mold is not more than 2°. The outer surface of the nozzle is frosted. The invention adopts cheap gypsum molds to prepare amorphous jewelry, has low price, simple process, high yield and high product surface quality, and is suitable for batch industrial production.

Description

technical field [0001] The invention relates to a jewelry manufacturing method, in particular to a manufacturing method of amorphous alloy jewelry and nozzle equipment specially used for the method. Background technique [0002] Amorphous alloy is a new type of metal material with a special structure. It has many excellent properties that the previous crystalline metal materials did not have. Its high wear resistance and corrosion resistance make it especially suitable as a preparation material for jewelry. [0003] At present, the preparation methods of bulk amorphous include water quenching method, copper mold casting method, high pressure casting method and so on. Among them, the water quenching method is to quench and cool the molten alloy to obtain an amorphous alloy. Due to the reason of the cooling medium, complex structures cannot be formed; the copper mold casting method and the high pressure casting method both use metal molds to cool, and can produce rods, plates,...
