Abstract
A method for measuring the temperature of molten metal received in a vessel, which includes covering the tip portion of a probe which includes 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 said probe projects into said vessel, at a position below the allowable lowest level of the molten metal received in said vessel; and maintaining the level of the molten metal at or above the allowable lowest level, thereby always immersing said probe into the molten metal received in said vessel.
