In large-scale ring rolling production, accurate blank cutting volume and reasonable process flow are very important to improve the processing quality, material utilization and production efficiency of largescale ring products, reduce energy consumption, production cost and labor intensity. In this paper, the technological process of large-scale ring rolling is systematically analyzed, including ingot cutting, ingot heating,ring blank making, ring blank reheating, ring rolling, ring heat treatment, ring machining and ring finished product detection. The calculation method of blank cutting volume of large-scale ring rolling production is established, and the calculation process includes volume calculation of rolling ring, volume calculation of ring blank, volume calculation of forging ring blank, volume calculation of forging blank and volume calculation of blank cutting. The research results of this paper improve the calculation accuracy of blank cutting volume and the actual production technology level of large-scale ring rolling.
