摘要
浇冒系统的设计是铸造工艺设计中很重要的内容．对球铁件浇注系统及冒口的设计原理及计算方法进行了深入的讨论．其中浇注系统的设计主要依据水力学中的伯努利方程，冒口的设计除了满足一般的补缩条件外，还特别考虑到球铁件的自补缩能力．其中涉及到的复杂铸件的体积计算，采用了组合形体法．同时，对浇冒系统的设计及模数计算均编制了相应的计算机程序，由此组成了一套实用的球铁件浇冒系统设计的 Ｃ Ａ Ｄ
The design of gating system and feeder is an important aspect in designins casting process.This paper makes a profound discussion on designing principle and calculation method for the gating system and the feeder of the nodular iron casting.The designing for gating system mainly depends on Benoli equaemendstion in hydraulics and besides meeting the normal feed demands,the designing for feeder especialy considers the self-feed capacity of the nodular iron.These also concern volume calculation of complex casting,which uses devision-composition method.In the meantime,the correspondent computer programs are programed for gating system and feeder designing as well as modulus calculation,which forms a set of applicable CAD software that can be used in gating system and feeder designing of the nodular iron casting.
