摘要

从Al2 O3 杂膜和液态金属结构分析入手

阐述了气体在铝杂 H2 系统中形核长大的全过程

提出“寄生机制”

并被试验和实践所证实 ;杂的存在是气体难以除净的关键限制因素

杂吸附着气

气寄生于杂

杂多气多

除气必排杂

排杂是除气的基础

Abstract

Based on the analysis of the molten metal structure and Al 2O 3 film. the whole process of nucleation and growth of gas （hydrogen） in aluminum inclusion hydrogen system were expounded and the mutual parasitic mechanism between inclusions and hydrogen in molten aluminum was proposed.The existence of inclusions was the key restrictive factor to be difficult for full gas removal. So inclusion removal from molten aluminum was the fundamental step of hydrogen removal.
