摘要

根据浓差电池法的原理研制了以高温固体电解质为基础的铝中氢传感器

应用该传感器开发了铝液含氢量测定仪。利用该测氢仪对铝液进行实时测氢试验

同时与第一气泡法测氢仪进行测氢对比研究。结果发现

该测定仪能够连续、快速准确地测定铝液中的氢含量。

Abstract

Based on the principle of concentration difference cell method

a hydrogen sensor was developed on the basis of the high-temperature solid electrolyte

and a hydrogen analyzer for aluminum alloy melt was developed by application of the sensor.The hydrogen analyzer was used for real-time measurement of hydrogen content in aluminum melt

and at the same time a hydrogen analyzer based on the first bubble method was also used to measure the hydrogen content of aluminum melt.By comparison of the results from two hydrogen analyzers

the new hydrogen analyzer can measure accurately and quickly the hydrogen content of the aluminum melt.
