Problems solved by technology

Due to the very active properties of high-temperature magnesium liquid, strontium liquid and aluminum liquid, the above two methods prepare magnesium-aluminum-strontium alloy. During the non-vacuum molten liquid pouring process, hydrogen evolution reaction occurs between the metal liquid and the water vapor in the air to obtain magnesium-aluminum-strontium alloy. The volume has obvious expansion. After cutting and observing the section, the alloy contains a large number of pores, which affect the performance of the magnesium-aluminum-strontium alloy; generally, the pores can be effectively eliminated under vacuum preparation conditions, but this method not only increases the cost, but also improves Difficulty

Embodiment 1

[0024] figure 1 It is a step flow chart of a method for preparing a magnesium-aluminum-strontium alloy according to an embodiment of the present invention.

[0025] Reference figure 1 The method for preparing a magnesium-aluminum-strontium alloy according to an embodiment of the present invention includes the following steps.

[0026] In step 110, the metal aluminum block is placed in a corundum crucible in a melting furnace for melting, and argon is filled into the melting furnace to obtain an aluminum molten liquid.

[0027] Specifically, first heat the temperature of the smelting furnace to 720°C, and put the corundum crucible as a smelting mold into it and heat it for about 5 minutes, so that the temperature of the corundum crucible is consistent with that of the smelting furnace; then put the 154.33g aluminum block into the corundum crucible During the melting of the aluminum block, argon gas needs to be filled into the melting furnace to prevent the aluminum block from being ox...

Abstract

The invention discloses a magnesium aluminum strontium alloy preparation method. The magnesium aluminum strontium alloy preparation method comprises the steps that (A) metal aluminum is arranged a smelting die in a smelting furnace to be molten to obtain aluminum melt liquid, wherein the smelting furnace is filled with shielding gas; (B) molten magnesium strontium alloy is added into the aluminum melt liquid and is pressed into the aluminum melt liquid to be molten completely for preset smelting time so as to obtain molten magnesium aluminum strontium alloy; (C) a smelting protective agent is flatly laid at the bottom of a casting mold and the casting mold is filled with shielding gas; (D) the molten magnesium aluminum strontium alloy is poured into the casting mold and covered with the smelting protective agent, and magnesium aluminum strontium alloy is obtained after the molten magnesium aluminum strontium alloy is naturally cooled. The magnesium aluminum strontium alloy preparation method adopts the method for combining the smelting protective agent with shielding gas filling, and air holes formed during molten magnesium aluminum strontium alloy casting are eliminated in non-vacuum melting and casting states.

Description

Technical field [0001] The invention belongs to the field of alloy preparation, and specifically relates to a method for preparing a magnesium-aluminum-strontium alloy. Background technique [0002] As a new type of heat-resistant magnesium alloy, magnesium-aluminum-strontium alloy has relatively better heat resistance compared with other magnesium alloys. At the same time, magnesium-aluminum-strontium alloy also has good casting properties, corrosion resistance and heat resistance. The preparation method of magnesium-aluminum-strontium alloy is mainly by mixing method, which is obtained by mixing and smelting high-purity metal magnesium, aluminum and strontium at a certain temperature through argon protection. The method has complicated equipment, long process flow and strontium burning loss. Large, the burning rate is about 20% to 30%; Mg-Sr, Al-Sr and Mg-Al master alloys can also be mixed to obtain Mg-Al-Sr alloys. This method has short process flow and less strontium burn-out...
