摘　　要：通过设计正交试验,分析了抛丸清理过程中钢丸粒度、抛丸时间等因素对铸件表面粗糙度的影响。结果表明:抛丸时间对铸件表面粗糙度的影响最大,抛丸时间越长,铸件表面粗糙度越低;其次为钢丸粒度,直径较小的钢丸有利于降低表面粗糙度;而钢丸抛射速度的影响较小。根据试验结果,对抛丸工艺进行了优化和探索。The influences of steel shot size, shooting time, and other factors on the surface roughness of iron castings were studied through orthogonal experiments. The results show that shooting time is the most significant factor for surface roughness, longer shooting time producing a better surface quality;, smaller size of steel shot helps to get lower surface roughness, which is the second important factor; the velocity of steel shot contributes little to surface roughness. The shot blasting technology was optimized according to the experimental results.
