1 前言 离心式集渣包一般多用于重要的大中型铸件的生产,而在一般小型铸件的生产中应用较少,其原因在于离心式集渣包体积较大,它的应用会浪费金属液,降低铸件的工艺出品率。但若设计恰当,用得巧妙,它在一般厚壁小件的生产中同样能取得良好的效果。近年来,笔者曾在本厂小深孔磨床的前盖、后盖、M224磨床的盖、接盘、法兰盘以及台钻的导 1 Introduction Centrifugal slag dregs generally more used for the production of important large and medium-sized castings, but in the production of small general-purpose castings used less, the reason is that centrifugal bulk dregs larger volume, its application would waste liquid metal, Reduce the production rate of castings. However, if designed properly and ingeniously used, it can also achieve good results in the production of small, thick-wall parts in general. In recent years, I have in the factory small deep hole grinder front cover, back cover, M224 grinder cover, then plate, flange and bench guide
