SQH-1型炉前快速测氢仪是我国自行研制的用于熔融铝及铝合金的快速测氢装置.十多年来,该装置广泛地应用于铝冶炼、铝合金铸造及铝加工等行业.我厂自1979年以来一直用它测定铝及铝合金熔体中的氢含量.SQH-1型炉前快速测氢仪所分析的组分是以PPM计算的氢气.因此对仪器的精度要求十分严格.而仪器在使用过程中极易引起分析误差,降低分析精度.我厂在SQH-1型炉前快速测氢仪的使用过程中不断地研究探索,积累了一些提高精度、减少分析误差的经验和方法,采用测氢过滤器就是一个有效的方法.
SQH-1 Rapid Pre-furnace Hydrogen Meter is a rapid hydrogen test device developed by our country for molten aluminum and aluminum alloy. For more than ten years, this device has been widely used in aluminum smelting, aluminum alloy casting and aluminum processing industries . Our factory has been using it to measure the hydrogen content in aluminum and aluminum alloy melt since 1979. The component analyzed by SQQ-1 rapid prototyping furnace is hydrogen calculated by PPM, so the precision requirement Very strict.While the instrument in the use of the process can easily lead to analysis errors, reduce the accuracy of analysis.Our factory in the use of SQH-1-type rapid pre-furnace hydrogen instrument in the process of continuous research and exploration, has accumulated some to improve accuracy and reduce analysis error The experience and methods, the use of hydrogen filter is an effective method.
