摘　　要：基于ProCAST铸造工艺模拟软件,采用冒口生长算法,并结合贪吃蛇算法的快速优化过程,对板类铸件冒口设计进行了优化,并与传统的模数设计法进行了比较。模拟分析结果表明,不同厚度的板状件,经过5到6次计算,可获得最优解,同时冒口体积减小46%以上,工艺出品率普遍提高了20%左右,铸件体积V_C与冒口体积V_R之间的关系可表示为V_C=(2.4~2.6)V_R。针对40 mm板状件的浇注试验结果表明,优化设计的冒口能满足铸件不存在缩孔缺陷的铸造要求,冒口的体积为模数法的48%,工艺出品率可提高22%,同时凝固时间缩短了550 s。Based on ProCAST casting process simulation software, compared with the traditional riser module design method, the new method in this experiment is based on the algorithm of riser natural growth, combined with the rapid optimization of snake algorithm. Regarding to slab with 40 mm thickness, simulation results show that after 5 to 6 computations, the optimal solution can be obtained, and the riser volume is reduced by more than 46% and the process yield is increased by about 20%. The relationship between the volume of casting and riser can be expressed as VC =（2.4-2.6）VR. The casting experiment shows that with the optimization design of riser, the castings have no defects, the volume of riser is 48% of the volume of the module method, the process yield can be increased by 22%, while shortening the solidification time of 550 s.
