摘要

利用选择性激光烧结（SLS）技术烧制某重型发动机缸盖水套砂芯并对工艺过程进行了研究。该重型发动机缸盖水套砂芯内腔形状复杂

外形尺寸大

浇注温度高。通过选用70

40目宝珠砂

加入适当配比酚醛树脂的覆膜砂

采用合适的激光烧结工艺参数和后固化温度和时间

一次浇注成功合格的大型缸盖铸件。

Abstract

The process of using selective laser sintering（SLS）technology to burn the water jacket of a heavy engine cylinder was analyzed.Heavy engine cylinder head water jacket has a complex cavity shape

large size and high pouring temperature.By choosing 70

40 mesh ceramsites and the appropriate ratio of phenolic resin coated sand

with the appropriate laser sintering process parameters and the curing temperature as well as time

the large qualified cylinder head casting was produced sucessfully.
