   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Fluid flow and heat transfer in industrial steel ladles during holding and teeming periods were simulated by using three mathematical numerical models and a physical hot-water model. Firstly, based on a finite-difference method, a one-dimensional heat conduction numerical model was established for predicting the heat loss fluxes through ladle wall, bottom and top slag layer.

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : In this thesis work, three mathematical models, each of which is suitable for simulating a particular process in the operation of steel ladles, have been developed. Firstly, by using a finite-difference mathematical method (FDM), a one-dimensional numerical model for calculating heat transfer through ladle wall, bottom and top slag layer was established.
