Abstract

In a recent decade,the titling gravity process is a very popular process for casting manufacturers,which is beneficial for the discharge of slag and gas from bottom to top during filling and sequential solidification of castings due to integrating the advantages of the bottom gating system and the top gating system.The double-barreled tank possesses a large and thin-wall structure with air-tightness requirement.Some casting defects,such as misrun and cold shut easily,occurred in the castings due to be difficult to form.Some defects in the double-barreled tank as slag and gas hole and the qualification rates of castings after machining and air-tightness testing are greatly improved by the titling gravity casting with optimized gating system and processing parameters.

摘要

可倾转式重力铸造集中了底注和顶注的优点

既有利于金属液充填型腔过程中渣气的排出

也有利于铸件的顺序凝固。汽车空调双管气室是大型薄壁类铸件

有气密性要求

成形困难

易产生浇不足、冷隔等铸造缺陷。利用可倾转重力铸造生产汽车空调双管气室

并通过对浇注系统和工艺参数的优化设计

能大大减少铸件内夹渣和气孔的缺陷

提高铸件机加工后和一次气密检验（无浸渗）的合格率。

Abstract

In a recent decade

the titling gravity process is a very popular process for casting manufacturers

which is beneficial for the discharge of slag and gas from bottom to top during filling and sequential solidification of castings due to integrating the advantages of the bottom gating system and the top gating system.The double-barreled tank possesses a large and thin-wall structure with air-tightness requirement.Some casting defects

such as misrun and cold shut easily

occurred in the castings due to be difficult to form.Some defects in the double-barreled tank as slag and gas hole and the qualification rates of castings after machining and air-tightness testing are greatly improved by the titling gravity casting with optimized gating system and processing parameters.
