The invention belongs to the technical field of metal materials, and particularly relates to a high-strength nodular cast iron traveling wheel and a preparation process thereof, and the high-strength nodular cast iron traveling wheel comprises the following components in parts by weight: 3.7152% of C, 2.0466% of Si, 0.4329% of Mn, 0.0326% of P, 0.0062% of S, 0.4464% of Cu, 0.0611% of Ni, 0.0422% of Cr, 0.0376% of Mo, 0.0278% of Ti and the balance of Fe. The high-end nodular cast iron walking wheel is made of iron instead of steel, and cost is low. The performance is stable and the cost performance is high. And a new way for manufacturing the high-end nodular cast iron traveling wheel by replacing steel with iron is opened up. The nodular cast iron walking wheel produced through the nodular cast iron matrix and Cu microalloying and low-temperature normalizing composite strengthening process is high in strength, good in plasticity, stable in performance, 100% in product percent of pass and high in cost performance. And a new way for manufacturing high-end nodular iron castings by replacing steel with iron is opened up.
