On-line Quantitative Analyzing of Molten Alloy Ingredient in Industrial Vacuum Smelting Process Using Laser-Induced Breakdown Spectroscopy

Laser-induced breakdown spectroscopy is used to quantitative analyze molten alloy ingredient in a 2-ton vacuum induction melt furnace. Measurements relative standard deviation of the main elements is 2~10%, trace element (< 0.2%) is lower than 25%.
