利用View Cast软件对灰铁轴承衬体充型和凝同过程进行了分析,通过凝同过程金属分布模拟了缩孔(松)产生的位置.采用挂砂外冷铁配合冒口使用对原方案进行了优化,最终消除了铸件中的缩孔(松)缺陷.再次模拟结果表明,改进方案合理可行,实现了平稳逐层充型和顺序凝固,从而有效地改善了铸件质量.

The mold filling and solidification stages of gray cast-iron bearing liner was analyzed by V-CAST software.The position of the shrinkage was simulated by metal distribution of solidification stage.The chill block hanged sand and the riser were used to optimize the original casting process.Finally the shrinkage of the casting was eliminated.The re-simulated results reveal that the optimized casting process is feasible and carrys out gradually-layered steady filling and sequential solidification.And the quality of castings effectively improve.
