Problems solved by technology
The use of protective gas can prevent the liquid magnesium alloy from reacting with air without introducing other impurities; however, the protective gas will overflow from the crucible when using a traditional open or semi-closed crucible, resulting in protection failure, severe oxidation and combustion

The invention relates to a magnesium alloy protective gas melting device. The magnesium alloy protective gas melting device comprises a cover plate and a ventilation device. The cover plate comprises a limiting part and a ventilation part which are connected together in a hinged manner. The ventilation part is provided with the ventilation device, a charging port is formed in the middle of the ventilation part, and a charging cover is arranged on the charging port. The limiting part is provided with a limiting plate, and the limiting plate makes contact with a crucible so that the cover plate can be positioned. The cover plate capable of covering the crucible is arranged, protective gas is introduced into the crucible through the ventilation device, magnesium alloy is melted in the relatively sealed environment, and the protective gas is continuously introduced in the melting process. The requirement for continuous protection is achieved, and contamination of alloy liquid is effectively avoided.
Description
technical field [0001] The invention relates to a melting device, in particular to a protective gas melting device for magnesium alloy, which can realize the melting process of the magnesium alloy by using the protective gas. Background technique [0002] This invention originates from the current melting process of magnesium alloys. At present, open melting is generally used. If flame retardant measures are not used for open melting, the molten magnesium alloy will directly contact with air after heating and melting, and a violent oxidation reaction will occur, and the oxidation reaction will release A large amount of heat keeps the alloy burning. In order to prevent the severe oxidation and combustion of magnesium alloys, reduce the defects of oxidized slag inclusions in magnesium alloys and improve the quality of alloys, the traditional process generally uses flux to cover the surface of magnesium alloys, and the flux will inevitably enter the alloy during the smelting an...
