钢中氢的含量对钢的性能有很大影响,随着钢材质量不断提高,对氢的测定无论在分析精度上、还是分析速度上均提出更高、更快速的要求.为了开展炼钢过程的质量控制和标准化工作,根据钢中氢标样研制过程中获得的一些数据和资料,对钢中测定氢的国内现状与存在的问题,提出一些看法.一、测定方法概况钢中测定氢,一般将试样置于真空或惰性气氛中熔融,或在熔点温度下加热,氢以H_2形式抽出.加热炉常有:电阻炉、高频炉和脉冲炉.
The content of hydrogen in steel has a great influence on the performance of steel, with the continuous improvement of the quality of the steel, the determination of hydrogen both in the analysis of precision, or analysis of the speed of both higher and faster requirements.In order to carry out the steelmaking process Of the quality control and standardization work, according to some of the data obtained in the process of developing hydrogen standard sample in the steel and data, put forward some opinions on the domestic present situation and existing problems in the determination of hydrogen in steel.First, the determination method Overview Determination of hydrogen, The sample is usually placed in a vacuum or inert atmosphere melting, or heating at the melting temperature, hydrogen H_2 in the form of extraction. Reed furnace often: resistance furnace, high frequency furnace and pulse furnace.
