METHOD FOR MEASURING TEMPERATURE OF MOLTEN METAL RECEIVED IN VESSEL

摘要

A method for measuring the temperature of molten metal received in a vessel, which comprises: covering the tip portion of a probe comprising a thermocouple housed in an alumina protecting tube, from inside to outside with a ceramic fiber and a quartz glass; attaching the covered probe to the side wall of a vessel so that the tip portion of the probe projects into the vessel, at a position below the allowable lowest level of the molten metal received in the vessel; and maintaining the level of the molten metal at or above the allowable lowest level, thereby always immersing the probe into the molten metal received in the vessel.
