介绍了一种具有封闭型腔的大型铸件的实型铸造工艺。其主要方法是

先造好上、下两个铸型

然后开箱

再将封闭位置的EPS切掉、填砂、最后再合箱浇注。该工艺方法不但提高了铸件的外观品质

同时也提高了铸件的内在品质。

Production of heavy hollow ring castings by full mold casting was described.The processing procedure was as follows:firstly

top mold and bottom mold were made;secondly

opening the mold and cutting the EPS at closed position and then filling sand;finally

the liquid metal was poured.The surface and inherent quality of the heavy hollow ring were evidently improved by the new full mold casting.
