摘　　要：从当前龙式耙齿浇注过程存在的问题出发,以性能更佳的30CrNiMo+Cr-Ni钢作为铸件材料,通过设计两种不同的龙式耙齿浇注系统方案,对浇注时间、浇口设计和浇道设计等参数进行计算,结合Pro-CAST软件进行模型的建立与导入、模型的网格划分、模拟参数的设置、边界条件的设计、热物性参数的设置和应力参数等数值模拟优化,最终获得龙式耙齿浇注系统优化设计方案,可为当前龙式耙齿浇注过程提供参考。Based on the existing problems in the casting process of the dragon-type rake teeth,it was designed for taking 30CrNiMo+Cr Ni steel with better performance as the casting material,two different dragon type rake teeth gating system schemes,by calculating parameters such as pouring time,gate design,and runner design.The models were optimized numerical simulation with establishing and importing models,meshing models,setting simulation parameters,designing boundary conditions,setting thermal properties parameters,and optimizing stress parameters in Pro CAST software.Finally,the optimized design scheme of the dragon-type rake teeth gating system is obtained,which can provide reference for the current dragon-type rake teeth gating process.
