The invention discloses a process for casting high-strength ductile iron walking wheels from resin sand, and relates to the technical field of resin sand casting. The process comprises the following steps: SS01, a hot spot of the rim and a hot spot of the wheel center need to be fed by an external feeding source; SS02, the resin sand is cast, and a casting head is placed at the wheel center; SS03,low-N resin with high furfuryl alcohol content and low urea content is selected; SS04, while the content of Si is reduced, a low rare earth 1-5 nodulizer is used, and a chilling block is adopted cooperatively; SS05, a casting system is larger than clay sand so as to avoid turbulent gas trapping and enhance gas exhaust and entrainment; SS06, high-strength ductile iron molten metal is smelted; SS07, a sand core is prepared; SS08, the wheel center of the walking wheels is fed; SS09, mechanical properties of walking wheel bodies are improved. The process has the advantages that pertinence is high, product quality is high, and product production cycle is shortened; the problems of casting defects and the like which are easily caused by casting of thick and large ductile iron parts from the resin sand are solved; the problems of broken graphite and bad spheroidization in casing of high-strength ductile iron parts from the resin sand are solved.
