The invention relates to a preparation method of an aluminum-titanium-boron wire grain refiner. The preparation method is implemented by continuous cast rolling after smelting and specifically comprises the following steps: (1) melting: adding a pure aluminum ingot into a crucible furnace, melting into liquid aluminum, and heating; (2) alloying: sequentially adding potassium chloride, potassium fluotitanate and potassium fluotitanate into the liquid aluminum in the liquid aluminum heating process in the step (1), and heating while stirring until the reaction is complete, thereby obtaining liquid alloy aluminum; (3) stirring, degassing and deslagging: transferring the liquid alloy aluminum prepared in the step (2) into an industrial-frequency core-free holding furnace, and stirring and degassing; and (4) continuous cast rolling: transferring the deslagged liquid aluminum into a mold, carrying out rubber filtration, crystallizing the wheel die cavity, carrying out continuous rolling by a continuous rolling machine, and taking up to obtain the aluminum-titanium-boron wire. The preparation method avoids the phenomenon of blistering or loosening since the liquid aluminum is oxidized or absorbs gas, and enhances the elongation percentage of the aluminum-titanium-boron wire.
