The invention provides a method for measuring a zinc element in electroslag steel by ICP-OES. The method comprises the steps of S1, sampling; S2, waiting for detection; S3, preparing a series of standard solutions; S4, forming a series of standard solutions; S5, establishing a working curve; S6, calculating the content of related elements in the sample according to the working curve; S7, determining working parameters of the instrument; S8, drawing a working curve; and S9, determining the content of the zinc element in the sample solution. According to the method, the number of used samples in the detection process is small, damage to the surface of the steel ingot is minimized, few chemical reagents are used, the whole process from the steel ingot to detection is rapid and environmentally friendly, and the method is simple, convenient and easy to implement. The method disclosed by the invention is small in matrix effect, wide in linear range, low in detection limit, good in precision, less in chemical interf
