Problems solved by technology
[0003] In the past and current magnesium alloy production, there are many deficiencies, such as poor equipment, low technological level, backward detection methods, serious environmental pollution, high labor intensity of workers, and many problems in production efficiency and alloy quality.
[0004] At present, the smelting method is commonly used to produce magnesium alloys. During the smelting process, oxidation and combustion of magnesium liquid often occur. In order to prevent the occurrence of oxidative combustion, a layer of flux sulfur powder is usually covered on the surface of the molten liquid to protect the magnesium alloy. Melt, sulfur powder will...

Embodiment Construction
[0104] The present invention will be further described below in conjunction with the accompanying drawings.
[0105] figure 1 , 4, 5, and 6, the implementation steps of the magnesium alloy preparation method are as follows:
[0106] Various equipment and valves for preparing magnesium alloys are placed in stop and closed positions, and are in the quasi-working state before preparation.
[0107] The crude magnesium is placed in the feeding car 17, and the raw material is sent to the conveying frame 19 through the conveying platform 18 for use in smelting.
[0108] Turn on the preheating furnace 1, and the preheating temperature of the crucible in the preheating furnace 1 is 400°-500°C. Put the flux into the bottom of the crucible, and then add the preheated coarse magnesium according to the proportioned weight, the preheating temperature is 120°-150°C, cover the lid 69, and keep it warm for a certain period of time.
[0109] After the crude magnesium is preheated, the crude ...

Abstract
The preparation method of magnesium alloy is characterized by that it adopts optimum metal element mixing ratio, respectively implements magnesium-refining process, molten magnesium alloying process and alloy liquor standing still and heat-insulating process, and also adopts the following measures of gas protection, negative pressure gas liquid guide, semi-continuously pouring, water circulation cooling, dust-removing cleaning and exhausting and spectral analysis so as to to raise purity of magnesium alloy and its quality.
Description
technical field [0001] The invention relates to a method for preparing a nonferrous metal magnesium alloy, which belongs to the technical field of production technology and preparation of nonferrous metal alloys. Background technique [0002] Among non-ferrous metal alloys, magnesium alloys have many characteristics in chemical composition, structure, and mechanical properties, such as small specific gravity, good rigidity, corrosion resistance, impact resistance, friction resistance, no deformation, non-toxic, non-magnetic, good shielding, and It has good thermal and electrical conductivity, is easy to process and shape, and is easy to recycle. The same volume of magnesium alloy is 36% lighter than aluminum alloy and 73% lighter than zinc alloy. It is widely used in aviation, aerospace, electronics, automobiles, computers, telecommunications and other fields. . [0003] In the past and current magnesium alloy production, there are many deficiencies, such as poor equipment,...
