SAMPLE HOLE DETECTOR FOR PROBE ADHERED TO SUB-LANCE

摘要

PURPOSE: Provided is a sample hole detector for a probe adhered to a sub-lance which detects location of the sample hole in a non-contact way to set its direction so that it helps to reduce malfunction in detection. CONSTITUTION: The sample hole detector for the probe adhered to the sub-lance comprises the parts of: the probe(2) which is adhered to the sub-lance and precipitated in molten steel to detect molten steel sample and the temperature of molten steel; a mark part(12) which is aligned at the rear side of a support pipe(4) for the probe as the same location as the sample hole(3) of the probe; a drive tool which uses a fixed bracket to rotate the probe for detecting the mark part; and a neighboring sensor which is connected to the drive tool.
