Problems solved by technology

This method has the disadvantages of high cost to varying degrees, flux inclusions in castings, and complicated equipment.
Therefore, the research, development and application of zinc-barium alloys are limited.
Therefore, in the industrial and national defense fields that are in urgent need of large-scale use of aluminum-barium alloys, there has always been a current situation that needs to be overcome, such as low output, cumbersome processes, and high costs.

Embodiment 1

[0018] A high temperature resistant Ba-Re-Te zinc alloy smelted at 450°C suitable for cold chamber die-casting. In terms of weight percentage, the chemical composition of the alloy is: Ba: 0.8wt.%, Re: 0.5wt.%; Te: 0.7wt.%, Ge: 2.5wt.%, V: 0.6wt.%, Pr: 0.3wt.% .%, the balance is zinc. The preparation method of the alloy: add the above-mentioned raw materials into the atmosphere-protected induction furnace, and use a silicon carbide crucible; induction heat to 450 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; put the alloy liquid in After standing at 450°C for 10 minutes, it is cast into the equipment at the same level as the hot top for semi-continuous casting into the required square and round ingots. The ingot moves down at a speed of 18m / min. The ingot can be used as casting raw material for pressure casting in the subsequent process to prepare zinc-barium alloy castings with complex shapes; the final hea...

Abstract

The invention discloses a high temperature-resistant Ba-Re-Te zinc alloy applied to cold chamber die casting and a processing process thereof. The alloy is prepared from the following components in percentage by weight: 0.4-1.2wt% of Ba, 0.4-0.8wt% of Re, 0.6-0.8wt% of Te, 2.0-4.0wt% of Ge, 0.5-0.8wt% of V, 0.2-0.4wt% of Pr and the balance of zinc. The zinc-barium alloy has excellent die-casting performance and can be used for producing long thin-walled parts; meanwhile, in the die casting process, the zinc-barium alloy can be casted by using cold chamber; the production efficiency is greatlyimproved; the energy consumption is reduced; the obtained products can be widely used in electric appliance manufacturing industry and radio industry.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc-barium alloy. Background technique [0002] In our country, zinc is one of the main metals that are focused on the development of non-ferrous metal industry. my country's zinc resource reserves are very rich, and it can also be exported in large quantities while meeting domestic demand. And replacing copper alloy and aluminum alloy with zinc alloy is of great significance in terms of saving energy, reducing material costs and rationally allocating domestic resources. With the continuous emergence of new die-casting technology, die-casting parts are no longer limited to the automobile industry and instrument industry, but gradually expanded to industries such as electronics industry and daily hardware. The main uses of zinc alloy castings in my country are toys (car models), daily hardware (handles, locks, sanitary ware), zippers, instrument parts and wear-resistant parts ...
