When the thin paper board 20 burns down after passing through the slag layer on the bath surface, the molten metal flows in from the reduced diameter hole 19 and fills the sampling vessel 15. When the paper tube comes into contact with the molten metal, it causes a splash to generate gas. However, at least in the vicinity of the reduced diameter hole 19, the generation of the splash is prevented by the non-splash materials 23 and 24.
Gas is not entrained in the molten metal flowing into the furnace.
During this time, the temperature of the molten metal is measured by the temperature measuring cartridge 25, and thereafter, when the probe body 11 is raised and pulled out of the molten metal bath, the molten metal collected by the sampling vessel 15 is solidified, and emission spectroscopy is performed as a solidified sample. Provided for analysis and other sample analyses.
