摘　　要：文章重点分析了同一生产条件下同一发动机缸盖的不同关键位置的二次枝晶间距值,其结果表明,缸盖的金属型铸造工艺是符合发动机性能设计要求的,探讨了二次枝晶间距与铸造工艺、产品性能设计要求之间的关系。分析了整个缸盖毛坯铸件的凝固顺序,从而推断铸造工艺的合理性。This work focused on analyzing the secondary dendrite arm spacing of different key positions in one cylinder head under the same normal production process. The result shows that the semi-permanent gravity cast process of eylinder heads met the requirement of the product design. The relationship among the secondary dendrite arm spacing, foundry technology and the product design were discussed. Based on the studying of the solidification sequence in the whole cylinder head casting, the foundry technology and processes were reasonable.
