ABSTRACT:
The invention discloses a method for measuring the temperature of a molten steel continuously, comprises the following steps: providing a tube that is made of double bushings, both of the inner and outer bushings being close at one end and open at another end; putting the close end of the tube into the molten steel in such a way that the ratio of the length of the tube under the surface of the molten steel to the inner diameter of the inner bushing is equal or greater than 15 and the ratio of said length to the outer diameter of the outer bushing is greater than 3; connecting the open end of the tube with an infrared detector; and calculating the temperature of the molten steel through evaluating the radiation emitted by the inner bushing at the end that was put under the molten steel by means of the detector. A tube to implement the method is also disclosed.
