The invention belongs to a steel oxidation treatment technology, and particularly discloses a method for measuring the thickness of a steel oxidation film. The method for measuring the thickness of the steel oxide film comprises the following steps: wiping and cleaning the surface, dripping a demolding liquid, dissolving the oxide film, wiping off residual liquid to form a round spot, wiping and cleaning with absolute ethyl alcohol, performing contact measurement on the inside and outside of the round spot by using a profiler probe, forming a contour pattern, measuring a height difference, and forming a test value of the thickness of the oxide film. By adopting the technical scheme, positioning and direct measurement are carried out on a steel part, the test piece is not damaged by cutting the sample, the test operation is simple, the efficiency is high, the oxidation film thickness measurement result is accurate and high in precision, the image is visual, and the problem that the steel oxidation film thickne
