DEVICE FOR CONTINUOUS MEASUREMENT OF MELTED STEEL TEMPERATURE IN INTERMEDIATE TUBING FITTING USING OPTICAL FIBER AND INFRARED RADIATION PYROMETER

摘要

A device for continuously measuring the temperature of molten steel in a tundish, using an optical fiber and an infrared pyrometer, designed to continuously measure the temperature of molten metal, as in the case of steel (1) in a tundish (2) in mechanized continuous casting, characterized by that by increasing the length of the ceramic tube (15) to reduce the instability of the temperature measurement with changes in the level of molten steel (1) inside the intermediate casting device (2), which is carried out using the inert gas outlet holes (16), and allows you to remove the quartz particles formed inside the ceramic tube (15) during the measurement, while the pressure control of the cooling inert gas is used to maintain the stability of the measurement; the ceramic tube (15) is held in the locating element (23) and is secured by means of hinged transom rods (17) secured with wing nuts or the like.
