Abstract：

Based on Simufact simulation, a finite element model of two-step ring rolling for large complex irregular section ring was established, and the equivalent strain and temperature distribution laws of ring component in the two-step ring rolling process were analyzed. The results show that the distributions of equivalent plastic strain and temperature of ring is extremely uneven. The equivalent plastic strain of ring gradually decreases from the inner and outer surfaces to the middle region during the inner profile ring rolling process,

and the temperature of ring gradually increases from the surface of ring to the center region. The lowest temperature is 762.512 ℃.

However, in the process of outer step ring rolling, the equivalent plastic strain of ring gradually decreases from the four corners of end surface to the center of lower part for ring, and its temperature distribution is roughly the same as that of the inner profile rolling of ring, with the lowest temperature of 818.441 ℃. A large complex irregular section ring with good overall filling effect, stable rolling process and meeting the design requirements is obtained by two-step ring rolling, which confirms that the simulation results can provide theoretical basis for the actual production of the two-step ring rolling process for large complex irregular section ring.
