摘要

讨论含锶量、熔炼温度、保温时间、炉气湿度以及氧化程度等工艺因素对铝合金液吸氢量的影响规律

并给出了铝液中的含氢量与各工艺因素之间的定量关系

同时

通过对熔液表面氧化膜形态的微观观察

解释了铝液氧化导致铝液吸氢的机理。

Abstract

The influences of strontium content

melting temperature

holding time

moisture content in the furnace atmosphere and oxi dizability of the melts on the hydrogen pick-up in aluminium alloy melts are researched systematically and the quantitative relations among these fac-tores and the hydrogen content are also given in this treatise

then the hydrogen pick-up mechanism of aluminium melts by oxidation of the melts is explained through micro-observation of morphology of the protective oxide skin of the melts
