中文摘要：论述了辊锻工艺的基本原理及特点。采取辊锻工艺对拉杆锻件进行制坯并使用有限元模拟软件模拟整个过程，得到无飞边、毛刺的坯料，符合制坯要求；通过分析其金属流动情况及应力场、应变场分布，从而证明辊锻工艺是较好的制坯工艺。
英文摘要：The basic principal, process characteristic of roll forging was introduced. Using roll forging process，the rod blank was made, the entire process was simulated by finite element simulation software, and the no flash and burr blank was gotten, which was in accord with the need of the blank process; by analyzing the metal flow and the distribution of stress field, it proves that the rolling method is a better process.
