ABSTRACT:
An apparatus for continuously measuring temperatures of molten metal including a thermocouple unit (A) and an immersion protection tube unit (B), wherein the thermocouple unit (A) comprises a thermocouple (1) having an end equipped with a temperature sensing element (8) and an opposite end connected to terminals (2), an insulator (9) of substantially one piece containing the thermocouple (1), a porcelain protection tube (6) of high airtightness containing the insulator (9), and a terminal box (3) having an extension sleeve (5) with which the upper part of the porcelain protection tube (6) is held and having a housing (20) which contains the terminals (2). The immersion protection tube unit (B) comprises an alumina-graphite protection tube (21), a holding sleeve (22) with a flange which is connected to the upper part of the alumina-graphite protection tube (21), and a connecting sleeve (26) connected with the holding sleeve (22). The porcelain protection tube is detachably inserted into the alumina-graphite protection tube (21) to allow easy removal of the thermocouple and alumina-graphite protection tube (21). Further, the alumina-graphite protection tube (21) is manufactured by a process of adding a resin type binder which has high carbonization yield to a compounding component formed of a mixture of graphite powder, a powder selected from and/or mixed with a powder of SiC derivatives, Si derivatives, ZrO.sub.2 --SiO.sub.2 derivatives, Al.sub.2 O.sub.3 --ZrO.sub.2 --SiO.sub.2 derivatives, and a powder of substantially granular and/or powdered alumina, and then subsequently kneading the mixture, forming it into a tube and sintering the formed tube.
