The invention discloses a method for restraining the coking and the carburization of a radiant tube of an ethylene cracking furnace, which comprises the following steps of: introducing petroleum hydrocarbon into the ethylene cracking furnace, and carrying out thermal cracking on the petroleum hydrocarbon by the radiant tube of the ethylene cracking furnace, wherein the inner surface of the radiant tube of the ethylene cracking furnace is provided with a layer of oxide film containing at least one of the following elements: Cr, Ni, Fe, Mn, La, Ce and Y, and the thickness of the metal oxide film is 0.1-20mu m. By the method disclosed by the invention, the coking and the carburization of the radiant tube of the ethylene cracking furnace can be remarkably restrained, and the transformation to the existing ethylene device is not needed; the inner surface of the radiant tube of the ethylene cracking furnace, which is provided with the metal oxide film, is replaced only when the radiant tube of the ethylene cracking furnace is needed to be replaced, and the effect is remarkable; and the sedimentation on the inner wall of the radiant tube of the ethylene cracking furnace can be reduced by over 60%.
