TEMPERATURE MEASUREMENT AND SAMPLING APPARATUS FOR VACUUM REFINING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a temperature measurement and sampling apparatus for a vacuum refining furnace, which enables temperature measurement and sampling of molten metal in the vacuum refining furnace while reliably maintaining the vacuum state inside the vacuum vessel, as well as has improved durability.SOLUTION: A temperature measuring and sampling device 101 for a vacuum refining furnace is configured such that a probe 1 for temperature measurement and sampling of a molten stainless steel is inserted from an opening 54a provided to a vacuum vessel containing the molten stainless steel therein. The temperature measuring and sampling device 101 includes a sealed container 2 provided surrounding the opening 54a, a shielding lid 10 provided inside the sealed container 2 and capable of opening and closing the opening 54a, a sealing material 54b provided between the opening 54a and the shielding lid 10, and a partition valve 20 capable of opening or closing the inner pipeline 54c of a sampling pipe 54 between the opening 54a of the vacuum vessel and the inside of the vacuum vessel. The probe 1 can be inserted to the vacuum vessel from the inside of the sealed container 2 via the opening 54a.
