  2. 11. A Study on the Thermal State of Steelmaking Ladles

    Author : Björn Glaser; Du Sichen; Petrus Christiaan Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steelmaking ladle; refractory; thermal conductivity; transient hot wire method; slag; peheating;

    Abstract : In the present thesis a study on the thermal state of steelmaking ladles was undertaken. The transient hot wire method was verified for thermal conductivity measurements on metallurgical slags and applied to ladle slag measurements. Temperature measurements on ladles in an industrial environment were carried out. READ MORE
