再谈浇注系统的补缩作用

Further Discussion on Feeding Action of Pouring System

从浇注位置、浇口尺寸、浇注时间几个侧面研究了浇注过程在大型铸铁件补缩中的能动作用；指出合理的设计浇注系统和浇注工艺，是实现大型铸铁件补缩的有效途径。

Active action of pouring process at feeding of large scale cast iron casting is studied from some factors of pouring position and time and the cross section size of pouring system.It's effcient way by rational design pouring system and foundry technology which can effectively solve the feedign problem of large scale cast iron casting.
