Real-Time Chemical Composition Analysis Implementation

This technical report details the implementation of real-time chemical composition analysis of crucibles at a primary aluminum casthouse using liquid-phase laser induced breakdown spectroscopy (LP-LIBS). The report outlines how DTE has developed analyzers that assess the chemical composition of molten aluminum at various process points. It describes the automation of the sampling process, which reduces the risk of error associated with manual sampling and laboratory analysis. The report presents findings from a simulation model that tested different scenarios of implementing DTE’s solution, highlighting reductions in crucible cycle time and operator handling time. It also discusses the advantages of DTE’s analyzers, including their performance in harsh conditions and the ability to deliver real-time results, which enhance process control and operator safety. The report concludes with an overview of a contract signed between Nordural and DTE for the installation of additional analyzers, emphasizing the benefits of optimized process control and increased throughput.
