The application discloses a method for refining magnesium-aluminum alloy crystal grains by carbon inoculation, and belongs to the technical field of magnesium alloy material processing. The method comprises the following steps: heating magnesium-aluminum alloy to 680-800 DEG C under a protective atmosphere, melting the magnesium-aluminum alloy, adding carbon inoculant hexachloroethane (C2Cl6), the adding amount being 0.1%-1.5% of the mass of the melt, adding by means of bell jar pressing, and keeping the temperature at 680-800 DEG C for 5-60 minutes, so that carbon and aluminum in the melt react in situ to generate high-density and dispersedly-distributed Al4C3 particles, which serve as effective heterogeneous nucleation cores of alpha-Mg, thereby significantly refining the crystal grains. The application is also provided with a tail gas treatment system for absorbing harmful gases such as Cl2. The method has the advantages of remarkable refining effect, strong anti-recession property, low cost, and suitability for magnesium-aluminum alloys with different aluminum contents, and solves the problems of instability, easy failure or environmental pollution in the prior art.
