Embodiment 1

[0024] Its prescription ratio of the magnesium alloy automobile wheel hub of the present invention is calculated by weight percentage: its manufacturing method adopts the following process steps:

[0025] The model of the magnesium alloy wheel hub of the present invention is: 0105-1350, diameter: 13 inches, width: 5 inches.

[0026] 1. Melting: Take 90% of the main raw material magnesium alloy ingot, preheat and dry it, drying temperature: 120-160°C, drying time: 1.5-2 hours; put the preheated magnesium alloy ingot into the crucible, heat up and melt, The temperature of molten magnesium is: 750-770°C. After melting for 30-40 minutes, turn on the protective gas, which is 25% N2+75% H2, to protect the magnesium alloy in the crucible, and add an intermediate alloy: aluminum agent (AI) : 9%, zinc agent (Zn): 0.5%, silicon agent (Si): 0.05%, iron agent (Fe): 0.002%, manganese agent (Mn): 0.444%, copper agent (Cu) : 0.002%, sodium agent (Ni): 0.002%; fully stir and mix evenly, and ...

Embodiment 2

[0036] Its formula ratio of magnesium alloy automobile wheel hub of the present invention is by weight percentage:

[0037] The model of the magnesium alloy wheel hub of the present invention is: 0102-1240, diameter: 12 inches, width: 4 inches.

[0038] The present invention gets main raw material magnesium alloy ingot: 89.5%, intermediate alloy gets: aluminum agent (AI) is: 9.5%, zinc agent (Zn) is: 0.5%, silicon agent (Si) is: 0.05%, iron agent ( Fe) is: 0.002%, manganese agent (Mn) is: 0.444%, copper agent (Cu) is: 0.002%, sodium agent (Ni) is: 0.002%; its manufacturing method adopts the process steps in embodiment one to make Magnesium alloy automobile wheel has beautiful appearance, light weight, high strength, good toughness, not easy to deform, and good corrosion resistance.

Embodiment 3

[0040] Its formula ratio of magnesium alloy automobile wheel hub of the present invention is by weight percentage:

[0041] The present invention gets main raw material magnesium alloy ingot: 90.5%, intermediate alloy gets: aluminum agent (AI) is: 8.3%, zinc agent (Zn) is: 0.5%, silicon agent (Si) is: 0.05%, iron agent ( Fe) is: 0.002%, manganese agent (Mn) is: 0.444%, copper agent (Cu) is: 0.002%, sodium agent (Ni) is: 0.002%; adopt the process step in embodiment one, two to make Magnesium alloy automobile wheels also meet the requirements of various indicators. Its model size can be formulated according to the needs of manufacturers.

Abstract

This invention relates to a kind of automobile hub of magnesium alloy and producing metho. It belongs to the die-casting technology of non-ferrous metal. The main raw material is magnesium alloy ingot. After preheating and drying, it is put in pot and melted under high temperature. Adding master alloy, mixing it fully. The following steps are refining and degassing, casting, heat treatment, machining, surface painting, drying, japanning. During the process, the degassing can reach standard easily. Magnesium liquid slag-removing is easy.

Description

technical field [0001] The invention relates to a magnesium alloy automobile wheel hub and a manufacturing method thereof, in particular to the hub processing of automobile wheel parts, and belongs to the technical field of smelting and die-casting of nonferrous metals. Background technique [0002] Magnesium alloy is currently the lightest metal structural material that can be used in industrial applications. Magnesium alloy not only has a small specific gravity (1.74g / cm 3 , which is only 64% of aluminum and 22% of steel), and has high strength and rigidity, so it has very attractive application prospects for various products that require lightweight. In particular, the urgent need for energy saving in the automotive industry, as well as the performance requirements of high-performance electronic products in terms of weight reduction and anti-interference, have a strong impetus to the promotion and application of magnesium alloys, resulting in an unprecedented development...
