涡流集渣现象的研究与分析

Research and Analysis on Phenomenon of Vortex Collected Slag

研究了涡流集渣原理,应用高分辨率对流格式数值模拟计算铸件充型过程的涡流。对实际的铁型覆砂铸造195曲轴在连杆轴颈处的局部夹杂形成原因引用数值模拟结果进行解释,改进浇注系统,消除局部夹杂。

Through analyzing the theory of slag collected by vortex and modeling the eddy current of mold filling process using highresolution convection scheme,it is explained that the formation of local inclusion at the connecting rod neck of 195 crankshaft for actual coated sand ironmold casting.And thus the gating system is improved,and local inclusion is eliminated.
