Hydrogen Analyser

Substantial improvements in the quality and reliability of aluminium alloy castings can be achieved if the hydrogen content of the melt is controlled. Aluminium alloys absorb hydrogen in the liquid state and unless it is removed, porosity will occur in the casting. Accordingly accurate measurement of hydrogen in the melt before casting is essential to ensure that degassing operations achieve the specified quality acceptance value. This measurement is provided on the foundry shop floor by the Hyscan hydrogen-in-aluminium analyser. The instrument is robust, mobile and easy to use and provides the operator with a quantitative measurement of hydrogen in the melt within five minutes of sampling. Apart from its use as a quality control tool, the instrument can be used for process investigation and for the evaluation of melt treatments. Financial benefits also accrue from lower scrap rates and reduced energy and labour costs. These savings often allow the retrieval of the capital cost of the instrument in less than one year. The Hyscan is manufactured by Severn Science (Instruments) Ltd, UK.
