前言 铜合金含氢量的炉前快速测定,是保证获得高质量铜液的重要手段,它可迅速地确定铜液是否达到规定的含氢指标,有效地降低铸件或铸锭的缺陷。从而提高工效,降低成本,保证产品质量。 1972年美国Flinn等人吸收了第一气泡法的优点,成功地将铝合金的Strauble Pf-eiffer减压测氢法移植到铜合金中来,并在以后的几年中进行了进一步的研究和应用推广。 Preface Rapid determination of the hydrogen content of copper alloy furnace before the furnace is an important means to ensure high-quality copper liquid, it can quickly determine whether the copper liquid reaches the required hydrogen content indicators, effectively reduce the defects of castings or ingots. To improve ergonomics, reduce costs and ensure product quality. In 1972, Flinn et al. Of USA absorbed the advantages of the first bubble method and successfully transplanted the Strauble Pf-eiffer aluminum alloy to the copper alloy, and further studies were carried out in the following years.
