耳冒口的推广应用

Ear-like Riser

一、概述耳冒口系根据铸铁件均衡凝固理论与有限补缩原则设计并推荐的新的冒口型式。它的特点是:冒口与铸件不是直接搭接。而是把冒口安放在铸件外延仲出的一个薄板上。这个薄板,形似一耳,故称耳冒口。耳冒口的引入位置。有利于不使铸件几何热节再过热,又有利于浇注后初始阶段的质量补缩。靠近热节。但不过热它;离开热节。

Ear-like Riser is one of new type feeding head, which possessed oF much characteristic feature such as shorter riser neck, thiner and wider of wall etc. So that this riser has had stronger shrinkage slag-off as well as degassing. This paper will be deseribed details of this rising head.
