Spectral standard sample preparation method of carbide-reinforced wear-resistant alloy

The invention belongs to the technical field of spectrum standard samples, and provides a preparation method of a spectrum standard sample of a carbide-reinforced wear-resistant alloy, which comprises the following steps: adding an alloy raw material into a vacuum induction melting furnace, carrying out first melting on the alloy raw material to form a melt, adding a coating composed of carbide and rare earth elements into the melt, and carrying out second melting to obtain a second melt; continuously heating to carry out second smelting on the melt; the melt is poured into a mold cavity and cooled to the room temperature along with a furnace, a cast ingot is obtained, and a pulsed magnetic field and pulse current are applied to the melt in the melt solidification process; annealing, quenching and tempering the cast ingot in sequence to obtain a primary sample; trimming and polishing the primary sample, and screening out a defect-free excellent sample; and performing uniformity analysis, selecting an excellen
