Abstract

The invention discloses a production process of a non-ferrous metal alloy casting, which relates to the technical field of alloy casting processing, and comprises the following steps: (1) smelting into liquid, (2) impurity removal treatment, (3) mold treatment, (4) casting treatment, and (5) die-casting formation. According to the production process, the phenomenon that destructive stress concentration is generated in the casting can be avoided, the uniformity of all structures of the casting is guaranteed, and therefore the strength and other qualities of the casting are well guaranteed; and (3) the method disclosed by the invention is simple in overall process, easy to popularize and apply, low in overall production cost, low in energy consumption and high in percent of pass.

Description

technical field [0001] The invention relates to the technical field of alloy casting processing, more specifically, it relates to a production process of non-ferrous metal alloy castings. Background technique [0002] Casting of non-ferrous metal alloys is to fill the mold with molten metal to obtain castings of parts with various shapes. Non-ferrous metal alloy castings are more common in the manufacture of beams, gas turbine blades, pump bodies, pylons, wheel hubs and engine crankcase covers, and are also widely used in the manufacture of household appliances, such as sandwich clips, baking trays, etc. [0003] Traditional non-ferrous metal alloy parts have the advantages of saving metal, reducing costs, and reducing working hours. However, during the casting process, they are very prone to problems such as pores, bubbles, shrinkage, and cracks, resulting in rough surfaces and loose casting structures, which seriously affect The performance and service life of castings re...
