Book Description
The radically new methodology of in-situ laser-produced plasma (LPP) analysis of molten metals, as developed at Lehigh University, has been implemented into an LPP sensor-probe system, ready for deployment at steelmaking facilities. The system consists of an LPP sensor-probe head, which is immersed into the molten metal bath for the short duration of measurement, a control console, an umbilical cord connecting the above two units, and a support console providing coolants and pneumatic supports to the control console. The Department of Energy funding has supported Phase III-A and -B of the project in a joint sponsorship with AISI, CTU 5-2 Consortium, and Lehigh University. The objectives have been to: (1) implement the molten metal calibration protocol for the LPP analysis methodology; (2) implement the methodology in the form of a second-generation LPP sensor-probe system, which facilitates real-time process control by in-situ determination of elemental composition of molten steel alloys; (3) deploy such developmental systems in steelmaking facilities; (4) upgrade the systems to a third-generation design; and (5) effect technology transfer by selecting a manufacturer of commercial LPP sensor-probe systems. Four of the five objectives have been fully met. The deployment objective has been partially realized at present. The full LPP sensor-probe system has been put through trial immersion runs at a foundry, but its deployment at steelmaking facilities has progressed to a stage where various issues of financial and legal nature are being codified into a formal agreement between a host site and Lehigh University.

Pages : 42
Book Description
A new method of molten metal analysis, based on time- and space-resolved spectroscopy of a laser-produced plasma (LPP) plume of a molten metal surface, has been implemented in the form of a prototype LPP sensor-probe, allowing in-situ analysis in less than 1 minute. The research at Lehigh University has been structured in 3 phases: laboratory verification of concept, comparison of LPP method with conventional analysis of solid specimens and field trials of prototype sensor-probe in small-scale metal shops, and design/production/installation of two sensor-probes in metal production shops. Accomplishments in the first 2 phases are reported. 6 tabs, 3 figs.
