摘要

在提出了镁熔体含氢量测定的数学模型的基础上

采用微型计算机及控制电路

开发出适合于炉前使用的镁合金熔液快速测氢系统。利用该装置

对AZ91镁合金熔液进行了含氢量的炉前快速检测试验研究。结果表明

AZ91镁合金熔液在气体保护熔炼条件下

每100g镁熔液含氢量在6

4cm3范围内

并随温度的增加而提高。

Abstract

We have developed a system suitable for rapidly measuring hydrogen content in magnesium alloy melt by using computer and controlled circuit based on a mathematical model for measurement of hydrogen content in magnesium alloy to measure hydrogen content in AZ91 magnesium alloy. The results show that hydrogen content in AZ91 magnesium alloy is 6

4 cm

per 100 g in the condition of gas protection

increasing with temperature increase.
