Aluminum alloy casting technology

Abstract

The invention belongs to the technical field of aluminum alloys, and particularly relates to an aluminum alloy casting technology. A hot melting device comprises a supporting frame and a hot melting box, wherein a center line position on the inner wall of the hot melting box is fixedly connected with a rotation rod; air through holes which are evenly distributed are arranged in the cavity of the rotation rod; the hot melting box is rotatably connected with the supporting frame through the rotation rod; the right side end surface of the supporting frame is fixedly connected with a motor; the outer surface of the rotation rod is fixedly connected with rotation wheels which are evenly distributed; the outer surface of the hot melting box is fixedly connected with guide rails which are evenlydistributed; and the bottom end surface of the supporting frame is fixedly connected with supporting grooves which are evenly distributed. The aluminum alloy casting technology is mainly used for solving the problems in the prior art that in an aluminum alloy manufacture process, argon and sodium salt introduced by certain manufacturers in an argon and sodium salt adding process is added after rawmaterials are subjected to hot melting, so that aluminum alloy raw materials and argon are in insufficient contact, the characteristics of magnesium in the raw materials are not completely stable, sothat magnesium is likely to be oxidized and meanwhile the sodium salt and the raw materials are not insufficiently mixed.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloys, in particular to an aluminum alloy casting process. Background technique [0002] Domestic research on low-pressure casting began in the 1950s. Since it was formally applied to industrial production, its development speed is extremely rapid. At present, domestic automobile and tractor manufacturers have formed specialized low-pressure casting workshops, and this process has also been widely used in shipbuilding, electrical machinery, instrumentation, light industry and national defense industries, and has developed from the earliest production of simple parts to the production of complex parts. In the 1960s, foundry workers in my country's shipbuilding industry system applied this process to casting copper alloy castings with a higher melting point to produce marine rudders, copper sleeves, valve bodies and small propellers. In the 1970s, the low-pressure casting process was used to pro...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the present invention proposes an aluminum alloy casting process. The present invention is mainly used to solve the problem that the tensile strength of the currently produced aluminum alloy is relatively poor, so that it is prone to deformation. In the prior art, the aluminum alloy During the production process, when some manufacturers add argon and sodium salts, the argon and sodium salts are often added after the raw materials are melted, resulting in insufficient contact between the aluminum alloy raw materials and argon. The characteristics of the magnesium in the raw material are not completely stable, which causes the problem that the magnesium is easily oxidized, and the mixing of the sodium salt and the raw material is insufficient.
