REPLACEMENT NAIL INSPECTING PROFILE OF MOLTEN METAL AND APPARATUS INSPECTING PROFILE OF MOLTEN METAL

摘要

The present invention, for a nail for measuring a molten metal profile for replacement and an apparatus for measuring a molten metal profile, which can measure a molten metal profile more accurately, provides a nail for measuring a molten metal profile for replacement which comprises: a load unit having an end and the other end wherein the other end is bound to the body unit of the apparatus for measuring a molten metal profile to be detachable; a first electrode unit bound to the load unit in at least the lengthwise direction of the load unit for moving by being linked to the load unit, where at least a part is deposited in the molten metal; and a second electrode unit bound to the load unit in at least the lengthwise direction of the load unit to be distanced from the first electrode unit for moving by being linked to the load unit, where at least a part is deposited in the molten metal. The first electrode unit and the second electrode unit have at least a part which can be exposed in the molten metal for receiving an electric signal through the body unit and measuring changes in the electrical characteristics of the molten metal according to the depth of deposition in the molten metal.
