摘要

本文提出了一种新的检测铝液中非金属夹杂物的原理及方法。检测原理方程已在冷态模拟试验中得到验证。用系统真空压力Pv和铝液非金属夹杂物浓度f

与时间的关系曲线可以用以分析夹杂物的含量;根据测试曲线的特点可以用以研究过滤机制;同时提供了确定检测参数和提高其检测精度的理论依据。

Abstract

A new principle and means of dynamic measuring of non-metallic inclusions in melten aluminium has been proposed and investigated by simulative techniques in this paper. A measuring principle has been established and verified quantitatively in simulative tests. The principle and means provides the basis for choosing the parameters and improving accurcy of assessment.
