摘要
介绍了轮轴铸造工艺设计与优化,以及在工艺设计和优化过程中采用ProCAST模拟软件对其进行模拟的结果。结果表明,铸件上部厚大部位热节大,原工艺浇注系统不利于铸件形成顺序凝固,补缩效果差,易形成缩孔、夹砂缺陷。通过改进浇道系统、芯子结构等工艺方法,减少了铸造缺陷,提高了产品合格率。
This paper introduces the casting process design and optimization of wheel axle steel castings and the process simulation results.The results show that there is a large hot spot in the thick part of the upper part of the casting,and the original pouring system is not conducive to the sequential solidification of the casting,which result in poor feeding effect,and make the defects of shrinkage and sand inclusion easy to form.By improving the pouring system and core structure etc,the casting defects are reduced and the qualified rate of the products is increased.
