摘要

用EPS做模型

干砂造型在负压的状态下浇注ZG2 5

系统研究涂层厚度对气化模铸造碳钢件表面含碳量变化。结果表明

适当的涂层厚度

铸件表面含碳量不会变化

随着涂层厚度的增加

铸件表面出现脱碳区—增碳区—正常区

Abstract

Effects of coating layer thickness on the surface C content in ZG25 carbon steel casting in EPC by using EPS pattern

dry sand mould

and vacuum pouring were studied systematically. The results showed that surface C content has no change with proper coating layer thickness while with increasing in the coating layer thickness casting surface will appear in following sequence: decarburized zone carburized zone normal zone moreover

with decrease in decarbured zone and increase in carburized zone graduately.
